Week 71 - Bash Shell Customisation (2 February 2004)
by
Adrian Mayo - Senior Editor for Mac OS X Unix
Monday - Shell Options
Use command 'shopt' to set shell options.
To set:
$ shopt -s <option>
To unset:
$ shopt -u <option>
To list:
$ shopt
Some useful options are illustrated below.
(1) Use 'cdspell' to correct minor typo's in filenames given to 'cd':
$ cd Dekstop
bash: cd: Dekstop: No such file or directory
Now set shell option 'cdspell':
$ shopt -s cdspell
$ cd Dekstop
Desktop
(2) Create short aliases for long directory names:
$ shopt -s cdable_vars
$ cal="/Users/saruman/Sites/calendar"
$ cd cal
/Users/saruman/Sites/calendar
Note: don't use the '~' alias in 'cdable' variables.
