The following trivial example program uses getopt() to handle two program options: -n, with no associated value; and -t val, which expects an associated value.
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>

main(int argc, char *argv[])

int flags, opt;

The list would not be updated for now. Don't write comments.

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

A quick attempt to automate opening up a tmux session with Irssi and its nicklist.pl running.
#!/usr/bin/env bash
# This should work whether you are already in a TMUX session or not...
# Irssi directory is assumed to be in the user's home dir
if [ -z "$TMUX" ]
then
tmux new-session -d -s ircuser
tmux split-window -tircuser -h -l20
tmux send-keys -tircuser "tmux send-keys -t0 \"irssi\" C-m; \
tmux send-keys -t0 \"/set nicklist_height \$(stty size | cut -f1 -d' ' -)\" C-m; \
