SYNOPSIS
daemon [-cf] [-p pidfile] command arguments ...
DESCRIPTION
The daemon utility detaches itself from the controlling terminal and executes the program specified by its arguments. The options are as follows: | -c | Change the current working directory to the root ("/"). | | -f | Redirect standard input, standard output and standard error to /dev/null. | | -p file | | | Write the ID of the created process into the file. Note, that the file will be created shortly before the process is actually executed, and will remain after the process exits (although it will be removed if the execution fails). | |
EXIT STATUS
The daemon utility exits 1 if an error is returned by the daemon(3) library routine, 2 if the pidfile is requested, but cannot be opened, otherwise 0.
DIAGNOSTICS
If the command cannot be executed, an error message is displayed on standard error unless the -f flag is specified.
