Start background process from .bashrc

Question

I realize that this might be a stupid issue but I can\'t solve it for hours even if digged stackoverflow site and google throughly.

Here is the base code in .bashrc

Answer 1

using bash (disown and &>/dev/null)
you need to run the app in the bg (gkrellm &) and then disown it

if ps -C gkrellm -o user | grep "$LOGNAME" &>/dev/null 
then echo "gkrellm is already running"
else gkrellm & disown
fi

if you want to be more portable and use posix sh
you will need to use nohup (part of coreutils and POSIX)
and also background it (nohup cmd &)
you'd also use .profile instead of .bashrc

if ps -C gkrellm -o user | grep "$LOGNAME" 2>/dev/null 1>&2
then echo "gkrellm is already running"
else nohup gkrellm &
fi

other approaches would include - as @Pontus answered - using tools like dtach, screen or tmux, where the command is executed in a detached environment.

by Pontus:
it would make more sense to use your window manager's autostart features

indeed :) as afaik gkrellm is a GUI app, it's better to autostart it, either using .xinitrc (if your login manager supports it), or your window manager's autostart facilities.
