it removes the directory entry for it. if no processes have it open and no other directory entries point to it (hard links), it releases the space.
Summary. All processes that are run using the nohup command will ignore the SIGHUP signal even upon exiting the shell. Once a job is started or executed using the nohup command, stdin will not be available to the user. By default, the nohup. out is used as the default file for stdout and stderr.
nohup. out file will be in location of your present working directory ,pwd. (the directory from where you executed command).
If you want to redirect the output of nohup command to file, just add it at the end of command after > redirection operator. Here is an example. In this case, the output of shell script will be sent to /home/ubuntu/data. txt file.
nohup some_command &> nohup2.out &
and voila.
Older syntax for Bash version < 4:
nohup some_command > nohup2.out 2>&1 &
For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with
nohup some_command > nohup2.out&
and it works just as I want it to. Leaving this here in case someone else is in the same situation. Running Bash 4.3.8 for reference.
Above methods will remove your output file data whenever you run above nohup command.
To Append output in user defined file you can use >>
in nohup command.
nohup your_command >> filename.out &
This command will append all output in your file without removing old data.
As the file handlers points to i-nodes (which are stored independently from file names) on Linux/Unix systems You can rename the default nohup.out
to any other filename any time after starting nohup something&
. So also one could do the following:
$ nohup something&
$ mv nohup.out nohup2.out
$ nohup something2&
Now something
adds lines to nohup2.out
and something2
to nohup.out
.
my start.sh file:
#/bin/bash
nohup forever -c php artisan your:command >>storage/logs/yourcommand.log 2>&1 &
There is one important thing only. FIRST COMMAND MUST BE "nohup", second command must be "forever" and "-c" parameter is forever's param, "2>&1 &" area is for "nohup". After running this line then you can logout from your terminal, relogin and run "forever restartall" voilaa... You can restart and you can be sure that if script halts then forever will restart it.
