The elgetopt program
elgetopt performs getopt-style parsing on the
arguments to an execline script.
elgetopt [ -D default ] optstring prog...
- elgetopt expects to find a valid number n of
arguments in the # environment variable, and n+1
environment variables 0, 1, ..., n.
It exits 100 if it is not the case.
- elgetopt pushes
environment variables starting with ELGETOPT_. To get the
previous values back, use
- elgetopt looks into 1, 2... for options,
as specified by optstring, which is a standard getopt
- If the -c switch is recognized, elgetopt
sets the ELGETOPT_c environment variable. The value
of that variable is the argument to the -c switch if
it has one, and 1 (or default if given) otherwise.
- After setting all recognized options, elgetopt makes
new #, 1, 2... "positional parameters" with
- elgetopt then execs into prog....
- -D default : use default as the
value for the ELGETOPT_c environment variable if there is
no argument to the -c switch. Default is 1. The
value is the same for all the options defined by elgetopt.
- GNU-style options are not supported.
