A collection of shell scripts (commands) to memorize a directory, change to another directory, and go back to the memorized one.
The commands are:
back # Go back to the memorized directory
cdm NEWDIR # Memorize current directory and change to NEWDIR
dirm [DIR] # Memorize the given DIR directory. If no directory is given then the current directory is memorized. Then you can change directory with traditional cd rather than cdm
ldirm # List memorized directory
showdirm # Show (Echo) memorized directory
up # Go one directory up (pretty much like cd .. )
upm # Memorize current directory and go one directory up
