Using Eval with Getopt
suggest changeWhile eval may not be needed for a pop
like function, it is however required whenever you use getopt
:
Consider the following function that accepts -h
as an option:
f()
{
local __me__="${FUNCNAME[0]}"
local argv="$(getopt -o 'h' -n $__me__ -- "$@")"
eval set -- "$argv"
while :; do
case "$1" in
-h)
echo "LOLOLOLOL"
return 0
;;
--)
shift
break
;;
done
echo "$@"
}
Without eval
set -- "$argv"
generates -h --
instead of the desired (-h --)
and subsequently enters an infinite loop because -h --
doesn’t match --
or -h
.
Found a mistake? Have a question or improvement idea?
Let me know.
