Check These Out

Execute MySQL query send results from stdout to CSV
You can, of course, tell MySQL to output results to a file and dictate how to terminate lines, etc. But sometimes you don't have access to the file system MySQL is running on, complicating outputting your results to a CSV, necessitating either annoying hacks or this simple command :D

Check syntax of all Perl modules or scripts underneath the current directory
Finds all *.p[ml]-files and runs a perl -c on them, checking whether Perl thinks they are syntactically correct

quickest (i blv) way to get the current program name minus the path (BASH)
Useful in shell scripts when you're trying to get the shell script name without the full path - and easier than awking or cutting. Bash pattern matching and variable manip is fun.

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

List bash functions defined in .bash_profile or .bashrc

Make a statistic about the lines of code
use find to grep all .c files from the target directory, cat them into one stream, then piped to wc to count the lines

another tweet function
This version of tweet() doesn't require you to put quotes around the body of your tweet... it also prompts you for password. It will still barf on a '!' character.

List only hidden files
You can omit the -d to see what's inside directories. In that case, you may want -a to see dotfiles inside those directories. (Otherwise you don't need -a since you're explicitly looking at them.)

convert a latex source file (.tex) into opendocument (.odt ) format
require the tex4ht package . You can open the file with openoffice , I use it much for correct my spelling and grammar .

Hiding password while reading it from keyboard
Allow to read password in a script without showing the password inserted by the user
