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.

Backup a file with a date-time stamp
$ buf myfile.txt This is useful when you are making small but frequent changes to a file. It keeps things organised and clear for another administrator to see what changed and at what time. An overview of changes can be deduced using a simple: $ ls -ltr

Far from my favorite, but works in sh and with an old sed that doesn't support '-E'

Check SSH public and private keys matching
Tested in bash4

get you public ip address

Delete all but the latest 5 files
yes 6 (tail from 6th line)

find .txt files inside a directory and replace every occurrance of a word inside them via sed

Watch and cat the last file to enter a directory
Great for watching things like Maildir's or any other queue directory.
