Hi,
On line 53 in the script, getopt is used with -u:
-u, --unquoted
Do not quote the output. Note that whitespace and special
(shell-dependent) characters can cause havoc in this mode (like
they do with other getopt(1) implementations).
This havoc is basically what Shellcheck is warning about.
Unfortunately it's not simply a matter of quoting the variable, since the
underlying problem is the way getopt is used.
Instead of -u, you can use -s bash, and then eval instead of word split:
args=$(getopt -o hd:w:c:P: --long help,domain:,warning:,critical:,path: -s
bash -n "$PROGRAM" -- "$@")
...
eval "set -- $args"
This way, no havoc is caused, and no shellcheck errors are reported.
Regards,
Vidar
This is a Nagios plugin to check the expiration date of a domain name.
It uses the "whois" command, which usually comes as a "whois" package.
Debian/Ubuntu: apt-get install whois
