ShellUtils

Some random shell scripts written to make my life bit easier.

push & pop

Shows a numbered list of saved directories and cd to the selected directory. Push will remember the current directory and pop[1] will cd to the selected directory. Create two aliases as follows :

alias pop='. ~/bin/pop.sh'

alias push='~/bin/push.sh'

[1] In order to cd, the pop script will have to be executed in the current shell.

pushPop.rc : push & pop on steroids

Add these shell functions to .bashrc or .profile. pop N will cd to the Nth directory in the list.

mpdLyrics.sh

Create the lyrics file for mpd from the current song's id3 tags.

backupScript.sh

Backup data using rsync. The directories to backup and the destinations are read from a control file.

Control File

The control file fields are separated by pipes (|). Lines starting with # characters are ignored.

The modified/deleted files are moved to the directory pointed by the CTRL|CTRL|backupdir entry.

CTRL|backupdir|/destinationFolder/deletions/

A Sample Control file:
