Backup all mysql databases to individual files on a remote server
It grabs all the database names granted for the $MYSQLUSER and gzip them to a remote host via SSH.

Diff two directories by finding and comparing the md5 checksums of their contents.
Compute the md5 checksums for the contents of two mirrored directories, then sort and diff the results. If everything matches, nothing is returned. Otherwise, any checksums which do not match, or which exist in one tree but not the other, are returned. As you might imagine, the output is useful only if no errors are found, because only the checksums, not filenames, are returned. I hope to address this, or that someone else will!

Trick find -exec option to execute alias
An alias cannot be executed as command in a find -exec line. This form will trick the command line and let you do the job.

Vim: Switch from Horizontal split to Vertical split
This allows to switch from horizontal to vertical split, putting the current buffer on the right side of the vertical split. To put it on the right use ^W-H. In a similar way, to switch from Vertical to Horizontal, do ^W-J (for bottom) and ^W-K (for top), but you vimers all guessed that one already :P

Shuffle mp3 files in current folder and play them.
* grep -i leaves only mp3 files (case insentitive) * sort -R randomizes list (may use GNU 'shuf' instead). * the sed command will add double quotes around each filename (needed if odd characters are present)
