02/15/2011 - The ImageMagick suite is capable of all types of conversion. Using it is simple: convert originalfile.format newfile.newformat convert automatically determines the original filetype from the file itself and chooses the output format based on the file extension you provide for the newfile. For example, convert file.ps file.gif will convert the file from postscript to GIF. see the convert(1) man page for more information on the formats it supports. Read more
02/15/2011 - That functionality is typically provided by the GNU Readline Library, which is used by many applications such as shells (bash, tcsh, zsh), mailreaders (mutt) and many others. However, some applications are not readline-aware but fear not, there is a way to make them behave like they are! We have installed the program rlwrap which provides readline functionality to any text input program. Read more

02/15/2011 - New UNIX groups, for the most part, are only created for "official" department purposes (students working together in a class created at the request of the professor, for example). If you have a reason to need a group, Email help@cs.utexas.edu, giving the name of the group you want, the login names of the people who need to be in it, and the purpose of the group. The group, if approved, will be created within one or two business days. Read more

02/15/2011 - First, you should try recovering the file from snapshots yourself; to learn how view the documentation on recovering files from snapshots. If that fails, email help@cs.utexas.edu and ask them to restore your files. Include the following information: When did you delete the file(s)? When did you create the file(s)? ("Not recently" is enough) When did you last change the file(s), before the day you deleted it/them? Read more
02/15/2011 - Please don't use "find /", as it's very slow and a real drain on the network. Use locate by typing locate [string], where [string] is the name of the file you want to find, or part of the name. It's more appropriate to use find to find something in a fairly small area, such as your home directory or a /projects directory, neither of which are searched by locate. The basic find syntax is 'find [path to search] [expression to search for]'; please read the man page for find, for more detailed information. Read more
02/15/2011 - The "public" software is anything installed in the /p or /public directory (typically, actual programs are in /p/bin). This software is installed by non-staff (students, researchers, or professors) and is not monitored, installed or maintained by the staff; if you're having trouble with a particular program, contact the person who installed that package (as shown by ls -l) directly, or email public@cs.utexas.edu, which is a mailing list of all people who maintain programs in /public.
