Check your unread Gmail from the command line
Just an alternative with more advanced formating for readability purpose. It now uses colors (too much for me but it's a kind of proof-of-concept), and adjust columns.

See why a program can't seem to access a file
Sometimes a program refuses to read a file and you're not sure why. You may have display_errors turned off for PHP or something. In this example, fopen('/var/www/test/foo.txt') was called but doesn't have read access to foo.txt. Strace can tell you what went wrong. E.g., if php doesn't have read access to the file, strace will say "EACCESS (Permission denied)". Or, if the file path you gave doesn't exist, strace will say "ENOENT (No such file or directory)", etc. This works for any program you can run from the command-line, e.g., strace python myapp.py -e open,access... Note: the above command uses php-cli, not mod_php, which is a different SAPI with diff configs, etc.

Customize time format of 'ls -l'
the --time-style argument to 'ls' takes several possible modifiers: full-iso, long-iso, iso, locale, +FORMAT. The +FORMAT modifier uses the same syntax as date +FORMAT. --time-style=+"%Y-%m-%d %H:%M:%S" strikes a happy medium between accuracy and verbosity: $ ls -lart --time-style=long-iso doesn't show time down to the nearest second, $ ls -lart --time-style=full-iso displays time to 10E-9 second resolution, but with no significant digits past the full seconds, also showing the timezone: $ -rw-r--r-- 1 bchittenden bchittenden 0 2011-02-10 12:07:55.000000000 -0500 bar

find files containing text
-l outputs only the file names -i ignores the case -r descends into subdirectories
