3 # A small example program for using the new getopt(1) program.
4 # This program will only work with bash(1)
5 # An similar program using the tcsh(1) script language can be found
6 # as parse.tcsh
7
8 # Example input and output (from the bash prompt):
9 # ./parse.bash -a par1 'another arg' --c-long 'wow!*\?' -cmore -b " very long "
10 # Option a
11 # Option c, no argument
12 # Option c, argument `more'
13 # Option b, argument ` very long '
14 # Remaining arguments:
15 # --> `par1'
16 # --> `another arg'
17 # --> `wow!*\?'
18
19 # Note that we use `"$@"' to let each command-line parameter expand to a
20 # separate word. The quotes around `$@' are essential!
21 # We need TEMP as the `eval set --' would nuke the return value of getopt.
22 TEMP=`getopt -o ab:c:: --long a-long,b-long:,c-long:: \
23 -n 'example.bash' -- "$@"`
