## Name nohup - Invoke a utility that will ignore SIGHUPs ## Synopsis ```sh $ nohup [args...] ``` ## Description `nohup` will invoke `utility` given an optional list of `args`, where at the time of the invocation it will ignore the SIGHUP signal. If the standard output is a tty, `utility` will append its standard output to the end of the file **nohup.out** in the current directory. If **nohup.out** fails to be created or opened for appending, `utility`'s standard output will instead be appended to the end of the file **$HOME/nohup.out**. If this also fails, `utility` won't be invoked. **nohup.out**'s permission bits are set to S_IRUSR | S_IWUSR when it is created. If standard error is a tty, one out of the following will occur: 1. If the standard output is open but not a tty, `utility` will redirect its standard error to its standard output. 2. If the standard output is a tty or is closed, standard error shall be appended to the end of **nohup.out** as described above. ## Arguments * `utility`: Utility to be invoked * `args`: Arguments to pass to `utility` ## Exit Status * 126 - `utility` was found but could not be invoked. * 127 - Either `utility` could not be found or an error occurred in `nohup`.
