nohup - invoke a utility immune to hangups
nohup  utility [arguments]
The nohup utility invokes utility with its arguments and at this time sets the signal SIGHUP to be ignored. 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.
Some shells may provide a builtin nohup command which is similar or identical to this utility. Consult the builtin(1) manual page.
The following variables are utilized by nohup:
| HOME || If the output file nohup.out cannot be created in the current directory, the nohup utility uses the directory named by HOME to create the file. |
| PATH || Used to locate the requested utility if the name contains no / characters. |
The nohup utility exits with one of the following values:
| 126 || The utility was found, but could not be invoked. |
| 127 || The utility could not be found or an error occurred in nohup. |
Otherwise, the exit status of nohup will be that of utility.
