This attempts to load a Perl Module (-M flag) and use version 9999, since no module has a version this high, Perl exits either a) telling you the version of the module installed or b) tells you it can't find the module.

Shows the ?rendering? for each of the 256 colours in both the bold and normal variant. Using seq is helpful to get even lines, passing $((COLUMNS*2)) to column sort-of-handles the nonprintable characters.

Shows the path if the module is installed or exit quietly (to simply avoid the 'No documentation found' msg).

Actually this is a shorter version that fits the 255 chars limit of this resource. The full version shows status in the right top corner:

Unlike other alternatives, this command only relies on bash builtins and should also work on windows platforms with the bash executable.

Sparseness corresponds to the number 128 and can be adjusted. To print all possible digits instead of only 0 and 1 replace RANDOM%2 by RANDOM%10 or RANDOM%16 to add letters [A-F].

Monitoring a log file with 'tail -f' is handy, but for emacs users monitoring the file with emacs is even better, because you can use all your familiar key bindings for copying regions, etc.

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system.

Maybe there's an easier way to set a timeout in the ssh options...

Generate a 18 character password from character set a-zA-Z0-9 from /dev/urandom, pipe the output to Python which prints the password on standard out and in crypt sha512 form.

This will check if a user is logged in using ssh and will log out the user automatically after the specified time in seconds without data retrieval on the server side.

Will work with bash and zsh so put it into your sourced shell file on the server side.

Be aware that users can change this themselves as it's just a envoronment variable.

Put this in your zshrc, source it, then run 'pkill -usr1 zsh' to source it in all open terminals. Also works with bash. More info: http://www.reddit.com/r/commandline/comments/12g76v/how_to_automatically_source_zshrc_in_all_open/
