tlsc: bug in command line processing

[GReagle]

This causes an error:

~$ tcpclient jabber.org 5223 tlsc sj -d /home/greagle/sj -u taiga -s jabber.org
tlsc: invalid option -- 'd'
tlsc [-hCH] [-c cert_file] [-f ca_file] [-p ca_path] program [args...]

but this works:

tcpclient jabber.org 5223 tlsc sj -- -d /home/greagle/sj -u taiga -s jabber.org

This causes an error too:

~$ tcpclient jabber.org 5222 sj -d /home/greagle/sj -u taiga -s jabber.org
tlsc: invalid option -- 'd'
tlsc [-hCH] [-c cert_file] [-f ca_file] [-p ca_path] program [args...]

but adding '--' doesn't help:

~$ tcpclient jabber.org 5222 sj -- -d /home/greagle/sj -u taiga -s jabber.org
usage: sj OPTIONS
OPTIONS:
        -u <user>
        -s <server>
        -r <resource>
        -d <directory>
        -D

Using the SJ_ environment variables circumvents this problem, but tlsc should work properly.

The problem seems to be a gnu-extension in getopt(3). Set the environment variable POSIXLY_CORRECT to force gnu-getopt to behave like POSIX-getopt. This should fix that issue.

Thank you younix. Setting POSIXLY_CORRECT does fix the problem. For reference, this GNU behavior is documented at https://www.gnu.org/software/libc/manual/html_node/Using-Getopt.html

It's me, "Jan". You are welcome :-)
