The explanation is that if the shell is unable to expand a wildcard, it just leaves it unexpanded, and since there were no files that matched the "*.java" in the directory where I executed the above commands, the "*.java" was passed unexpanded to "find". To see the effect of this, try a command such as "echo *.c" first in a directory that contains at least one file that matches the wildcard and then in a directory that doesn't. Well, *I* was glad to clear that up. -- blm From bmassing@Athena.CS.Trinity.Edu Thu Feb 12 19:53:53 2004 Received: from Athena.CS.Trinity.Edu (athena.cs.trinity.edu [131.194.131.185]) by Sol.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i1D1rrqf008396 for ; Thu, 12 Feb 2004 19:53:53 -0600 Received: from Athena.CS.Trinity.Edu (localhost.localdomain [127.0.0.1]) by Athena.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i1D1rnpS003323 for ; Thu, 12 Feb 2004 19:53:49 -0600 Received: (from bmassing@localhost) by Athena.CS.Trinity.Edu (8.12.8/8.12.8/Submit) id i1D1rnfU003321 for cs3190unix-list@mail.cs.trinity.edu; Thu, 12 Feb 2004 19:53:49 -0600 Date: Thu, 12 Feb 2004 19:53:49 -0600 From: Berna Massingill To: cs3190unix-list@sol.cs.trinity.edu Message-ID: <20040213015349.GA3293@cs.trinity.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Subject: [CS3194-list] homework 3 on Web X-BeenThere: cs3190unix-list@mail.cs.trinity.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: Mailing list for CSCI 3190 (Unix Power Tools) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 13 Feb 2004 01:53:53 -0000 I've posted Homework 3 (linked from the ``lecture topics and assignments'' page), due Monday.

And a couple of general hints and tips, in response to comments from students: If you don't like reading things online, you can always print out the parts of a document you want to read. (It wouldn't be environmentally conscientious to print out the whole of some of the documents I'm assigning readings in, but you should be able to print selected pages. If you're having trouble, feel free to ask for tips/help.) If you find yourself spending more hours on the homework than you care to and getting frustrated, please don't hesitate to ask for help.

Here's a bit of a follow-up. Asked to clarify what he's doing, Dr. Eggen writes: >> you have two windows open, and you want to quickly grab some text >> from one window and paste it into the other. on the left is the text >> you wish to grab. on the right is a vim session in input mode. you >> sweep (left) mouse through the text on the left, you go to the right >> window and paste with middle mouse. the text with autoindent goes >> scattering across the window and ... well, not good. >> i simply unalias vi (to get old vi) and in .exrc set noautoindent. >> that works but deprives me of some of the features of vim that i >> like. A semi-solution to the problem is to unset autoindent before doing the paste. Before going into insert mode to paste, ":set noai". Then do the paste. The indentation should be pretty much like whatever you grabbed from the other window. Then ":set ai" to turn autoindent back on. An alternative is ":set paste" before pasting and ":set nopaste" after. This resets autoindent and some other options (":help paste" to read more). For editing code, though, I like vim's "automatic code indentation" feature (":help C-indenting" for possibly more than you wanted to know). With this feature on, vim figures out how much to indent each line based on the programming language it thinks you're writing (C for .c files, Java for .java files, etc.). Here are the options I use to get behavior I like (4-space "tab stops", all indenting done with spaces): set nocompatible filetype on filetype indent on set textwidth=80 set softtabstop=4 set expandtab set cindent shiftwidth=4 set ruler set backspace=2 set formatoptions=tcql syntax on Put these lines in a file, say .vimrc-code, and then start vim by typing "vim -u .vimrc-code filenametoedit". If you want these options always, just name the file .vimrc in your home directory and start vim in the normal way. With this setup, you just type as if you were starting each line at the left margin (don't try to indent/unindent), and vim indents it in a way that's usually reasonable. If you don't like a particular line, you can go back and change it manually. This doesn't really solve the problem with pasting, but it does provide a reasonable recovery: To "reformat" a line that has been messed up, you put the cursor on the line and type "==" (two equals signs). You can reformat whole sections too. The easiest way is to select the section with the "visual mode" feature and then type a single equals sign. Hope this helps someone. -- blm From bmassing@Athena.CS.Trinity.Edu Wed Mar 31 19:30:41 2004 Received: from Athena.CS.Trinity.Edu (athena.cs.trinity.edu [131.194.131.185]) by Sol.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i311Ufqf005172 for ; Wed, 31 Mar 2004 19:30:41 -0600 Received: from Athena.CS.Trinity.Edu (localhost.localdomain [127.0.0.1]) by Athena.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i311UapS005390 for ; Wed, 31 Mar 2004 19:30:36 -0600 Received: (from bmassing@localhost) by Athena.CS.Trinity.Edu (8.12.8/8.12.8/Submit) id i311UaYF005388 for cs3190unix-list@mail.cs.trinity.edu; Wed, 31 Mar 2004 19:30:36 -0600 Date: Wed, 31 Mar 2004 19:30:36 -0600 From: Berna Massingill To: cs3190unix-list@sol.cs.trinity.edu Message-ID: <20040401013036.GA5261@cs.trinity.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Subject: [CS3190unix-list] cs3190 -- syllabus changes as discussed Monday X-BeenThere: cs3190unix-list@mail.cs.trinity.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: Mailing list for CSCI 3190 (Unix Power Tools) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 01 Apr 2004 01:30:41 -0000 I've updated the syllabus online to reflect what we decided Monday in class. To recap: In the syllabus I said everyone would be required to do some sort of project in addition to the required homeworks. This will no longer be required, and total points for homework will be about 100 (rather than the 200 estimated in the syllabus). Anyone who wants to earn extra points, however, has the option of doing a project. The amount of extra credit will be determined by the project's scope (maximum of 10 points for something comparable to one homework, etc., up to a maximum of 30 points) and quality. If this sounds interesting to you, come talk to me about project ideas. Obvious possibilities are programming projects implemented using shell scripts and/or makefiles. The due date will be no earlier than the last day of classes (April 30). Your final average will be computed as the sum of attendance points (maximum 50), homework points (maximum about 100), and project points, divided by the maximum points for attendance and homework. As stated in the syllabus, 90% is at least an A-, 80% at least a B-, etc. There is some possibility that the actual dividing lines between letter grades will be lower, but for this course I suspect this is unlikely, since the median midterm letter grade was an A- without a "curve". Questions? Please ask! -- blm From bmassing@Athena.CS.Trinity.Edu Fri Apr 23 21:58:23 2004 Received: from Athena.CS.Trinity.Edu (athena.cs.trinity.edu [131.194.131.185]) by Sol.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O2wMqf002416 for ; Fri, 23 Apr 2004 21:58:23 -0500 Received: from Athena.CS.Trinity.Edu (localhost.localdomain [127.0.0.1]) by Athena.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O2wMCG011922 for ; Fri, 23 Apr 2004 21:58:22 -0500 Received: (from bmassing@localhost) by Athena.CS.Trinity.Edu (8.12.8/8.12.8/Submit) id i3O2wMOS011920 for cs3190unix-list@mail.cs.trinity.edu; Fri, 23 Apr 2004 21:58:22 -0500 Date: Fri, 23 Apr 2004 21:58:22 -0500 From: Berna Massingill To: cs3190unix-list@sol.cs.trinity.edu Message-ID: <20040424025822.GA10981@cs.trinity.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Subject: [CS3190unix-list] cs3190 -- homework solutions X-BeenThere: cs3190unix-list@mail.cs.trinity.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: Mailing list for CSCI 3190 (Unix Power Tools) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 24 Apr 2004 02:58:23 -0000 As you probably know from earlier mail, I've graded homework 4 and sent grades/comments by e-mail. (So, if you think you turned something in but didn't get a grade, let me know ASAP.) I've also looked at what everyone turned in for homework 5 (the one that asks you to work through the vim or emacs tutorial). Everyone turned in something plausible, so everyone got full credit. I put together a "sample solution" consisting of things people said they had learned and might find useful and linked it from the class "lectures and assignments" page. Time permitting, it's something to look at. I've also posted sample solutions for homeworks 6 and 7 and am working on getting them graded. -- blm From bmassing@Athena.CS.Trinity.Edu Fri Apr 23 22:03:39 2004 Received: from Athena.CS.Trinity.Edu (athena.cs.trinity.edu [131.194.131.185]) by Sol.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O33dqf002678 for ; Fri, 23 Apr 2004 22:03:39 -0500 Received: from Athena.CS.Trinity.Edu (localhost.localdomain [127.0.0.1]) by Athena.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O33dCG012020 for ; Fri, 23 Apr 2004 22:03:39 -0500 Received: (from bmassing@localhost) by Athena.CS.Trinity.Edu (8.12.8/8.12.8/Submit) id i3O33dt1012018 for cs3190unix-list@mail.cs.trinity.edu; Fri, 23 Apr 2004 22:03:39 -0500 Date: Fri, 23 Apr 2004 22:03:39 -0500 From: Berna Massingill To: cs3190unix-list@sol.cs.trinity.edu Message-ID: <20040424030339.GA11943@cs.trinity.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Subject: [CS3190unix-list] "anything else from the command line?" minute essay X-BeenThere: cs3190unix-list@mail.cs.trinity.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: Mailing list for CSCI 3190 (Unix Power Tools) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 24 Apr 2004 03:03:39 -0000 Remember the minute essay question "anything else you want to do from the command line?"

The lab machines are set up so that regular (non-root) users can do this for diskettes and CDs. To access a diskette, put it in the drive and type "mount /mnt/floppy". You then have access to the diskette through directory /mnt/floppy. (E.g., "ls /mnt/floppy" will list the files/directories.) When you're done, cd out of the /mnt/floppy directory and type "umount /mnt/floppy". To access a CD, follow the same procedure but with directory /mnt/cdrom. The names /mnt/floppy and /mnt/cdrom are defined in /etc/fstab. (So they might be different on someone else's system, but you can look in /etc/fstab to see what names to use.) -- blm From bmassing@Athena.CS.Trinity.Edu Fri Apr 23 22:22:17 2004 Received: from Athena.CS.Trinity.Edu (athena.cs.trinity.edu [131.194.131.185]) by Sol.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O3MHqf003196 for ; Fri, 23 Apr 2004 22:22:17 -0500 Received: from Athena.CS.Trinity.Edu (localhost.localdomain [127.0.0.1]) by Athena.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O3MHCG012299 for ; Fri, 23 Apr 2004 22:22:17 -0500 Received: (from bmassing@localhost) by Athena.CS.Trinity.Edu (8.12.8/8.12.8/Submit) id i3O3MHg8012297 for cs3190unix-list@mail.cs.trinity.edu; Fri, 23 Apr 2004 22:22:17 -0500 Date: Fri, 23 Apr 2004 22:22:16 -0500 From: Berna Massingill To: cs3190unix-list@sol.cs.trinity.edu Message-ID: <20040424032216.GA12165@cs.trinity.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Subject: [CS3190unix-list] ftp X-BeenThere: cs3190unix-list@mail.cs.trinity.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: Mailing list for CSCI 3190 (Unix Power Tools) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 24 Apr 2004 03:22:17 -0000 Someone else asked about command-line ftp clients. The preferred one is probably sftp, which uses ssh to encrypt what's being sent. "sftp host" or "sftp user@host" will get it started; type "help" at that point to see what options you have, or read the man page. (Some useful commands: "get" to get a file from the remote host, "put" to send a file to the remote host.) If that doesn't work, you can use ftp ("ftp host", and it prompts for your username), but it transmits everything in clear text, including your password, so it's considered to be less secure. -- blm From bmassing@Xena00.CS.Trinity.Edu Fri Apr 23 23:16:42 2004 Received: from Xena00.CS.Trinity.Edu (xena00.cs.trinity.edu [131.194.131.90]) by Sol.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O4Ggqf004671 for ; Fri, 23 Apr 2004 23:16:42 -0500 Received: from Xena00.CS.Trinity.Edu (localhost.localdomain [127.0.0.1]) by Xena00.CS.Trinity.Edu (8.12.8/8.12.8) with ESMTP id i3O4GgCg006141 for ; Fri, 23 Apr 2004 23:16:42 -0500 Received: (from bmassing@localhost) by Xena00.CS.Trinity.Edu (8.12.8/8.12.8/Submit) id i3O4Gg5L006139 for cs3190unix-list@mail.cs.trinity.edu; Fri, 23 Apr 2004 23:16:42 -0500 Date: Fri, 23 Apr 2004 23:16:42 -0500 From: Berna Massingill To: cs3190unix-list@sol.cs.trinity.edu Message-ID: <20040424041642.GA5800@cs.trinity.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Subject: [CS3190unix-list] games X-BeenThere: cs3190unix-list@mail.cs.trinity.edu X-Mailman-Version: 2.1.1 Precedence: list List-Id: Mailing list for CSCI 3190 (Unix Power Tools) List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 24 Apr 2004 04:16:43 -0000 Someone else asked about games. You can (probably) launch any graphics-type game, if you can find its path name. But the question got me thinking about old-time text-mode games .... The standard RH 9 distribution doesn't really include any of them, but I found a collection of them out on the Web and installed them. You'll find them in /users/cs3190u/games/games. You can read the corresponding man pages with, e.g., "man -M /users/cs3190u/games/man hangman". Not everything works -- for security reasons, I didn't enable global score files -- but you can get an idea of what such games are like. Some that seem reasonable playable are boggle, hangman, robots, and tetris-bsd. Commands rain and fortune aren't exactly games but are entertaining. As they say -- "for what it's worth." -- blm P.S.
