Remove a range of lines from a file

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

A nice way to show git commit history, with easy to read revision numbers instead of the default hash

check open ports without netstat or lsof

Who invoked me? / Get parent command
Get the name of the parent command. This might be helpful, if you need to react on that information. E. g. a script called directly via ssh has got sshd as parent, manually invoked the parent process will probably be bash

Selecting a random file/folder of a folder
Also looks in subfolders

Prepend section dates to individual entries in a summary log file
Searches for dates on lines by themselves. Uses that date to prepend all rows that contain SEARCHSTRING with the date, until it reaches another line with a date by itself. This fixed an issue with a specific log export where there would be a date, followed by all of the entries for that date.

Benchmark SQL Query
Benchmark a SQL query against MySQL Server. The example runs the query 10 times, and you get the average runtime in the output. To ensure that the query does not get cached, use `RESET QUERY CACHE;` on top in the query file.

dmesg with colored human-readable dates
Use sed to color the output of a human-readable dmesg output

Play radio stream with mplayer
Above command will play Virgin Radio Dubai
