Questions tagged [nohup]

The nohup standard utility and the nohup builtin from shells like csh, which cause the SIGHUP signal to be ignored

If you're using the tag, and are specifically using the GNU/coreutils implementation (the default on desktop and server Linux distros), also add or , since the GNU implementation also redirects the output of the command from a non-readable file, which results in behaviour not specified by the POSIX standard. If your question is about running processes in background, also add or , and any other relevant tags; do NOT use as an umbrella term for long-running jobs which should survive a logout or similar.
