to be ignored,
then executes
utility
along with any arguments.
If the standard output is a terminal, the standard output is
appended to the file
nohup.out
in the current directory.
If standard error is a terminal, it is directed to the same place
as the standard output.
If the output file
nohup.out
cannot be created in the current directory,
nohup
attempts to create the file in the user's home directory.
If the file
nohup.out
cannot be created,
either in the current directory or the user's home directory,
nohup
will exit without invoking
utility,
with an exit value as described below.
Otherwise, the exit status of nohup will be that of utility.
