Editing: getopt-example.bash
#!/bin/bash # A small example script for using the getopt(1) program. # This script will only work with bash(1). # A similar script using the tcsh(1) language can be found # as getopt-example.tcsh. # Example input and output (from the bash prompt): # # ./getopt-example.bash -a par1 'another arg' --c-long 'wow!*\?' -cmore -b " very long " # Option a # Option c, no argument # Option c, argument 'more' # Option b, argument ' very long ' # Remaining arguments: # --> 'par1' # --> 'another arg' # --> 'wow!*\?' # Note that we use "$@" to let each command-line parameter expand to a # separate word. The quotes around "$@" are essential! # We need TEMP as the 'eval set --' would nuke the return value of getopt. TEMP=$(getopt -o 'ab:c::' --long 'a-long,b-long:,c-long::' -n 'example.bash' -- "$@") if [ $? -ne 0 ]; then echo 'Terminating...' >&2 exit 1 fi # Note the quotes around "$TEMP": they are essential! eval set -- "$TEMP" unset TEMP while true; do case "$1" in '-a'|'--a-long') echo 'Option a' shift continue ;; '-b'|'--b-long') echo "Option b, argument '$2'" shift 2 continue ;; '-c'|'--c-long') # c has an optional argument.
