Custom .profile / .bashrc config

/ Published in: Bash

Creates aliases 'save' & 'show' for the subsequent creation of on-the-fly aliases to frequently used directories.

You can save a directory using an abbreviation of your choosing. Eg. 'save foo'

Highlighted TextExpand

# The following aliases (save & show) are for saving frequently used directories
# You can save a directory using an abbreviation of your choosing. Eg. save ms
# You can subsequently move to one of the saved directories by using cd with
# the abbreviation you choose:
#   % cd ms  
# (Note that no '$' is necessary with 'cd'.)
#
# You can also use in other operations:
#   % cp file1 file2 file3 $acme
# (Here the $ is necessary since (unlike 'cd') the 'cp' command does not
# automatically look for shell variables.)

}
source ~/.dirs  # Initialization for the above 'save' facility: source the .sdirs file
shopt -s cdable_vars # set the bash option so that no '$' is required when using the above facility
