Do a git commit using a random message.

Synchronize date and time with a server over ssh
using -u is better for standardizing date output and timezones, for servers in different timezones.

tar and bz2 a set of folders as individual files
This version will work if "*screenflow" returns any results with weird characters, and will actually compress the tarballs.

Command line calculator
This function defines a command line calculator that handles everything pythons math module can handle, e.g. trigonometric functions, sqrt, log, erf, ... (see http://docs.python.org/library/math.html). It even knows about the constants pi and e.

Insert the last argument of the previous command
for example if you did a: $ ls -la /bin/ls then $ ls !$ is equivalent to doing a $ ls /bin/ls

In place line numbering
Add permanent line numbers to a file without creating a temp file. The rm command deletes file10 while the nl command works on the open file descriptor of file10 which it outputs into a new file again named file10. The new file10 will now be numbered in the same directory with the same file name and content as before, but it will in fact be a new file, using (ls -i) to show its inode number will prove this.

Locate config files of the program
Locate config files of the program. May not be used for interactive programs like vim.
