如何“ nohup”命令并记录“ time”的输出

Question

I want to time a long running script, and log the output of the time command to a log file, like so:

(time php mylongcommand.php) &> dump

This works, but what if I want to nohup the command so I can check the logs later. The following code does not work:

nohup (time php mylongcommand.php) &>dump &

Any suggestions?

Answer 1

(time php mylongcommand.php) &> dump < /dev/null &

Should also do the trick. By redirecting input from /dev/null and using & to put the process into the background, the same effect is obtained as if you used nohup . You should be able to exit your shell session without any stopped jobs error, and the process will continue to run.

Answer 2

卸下支架：

nohup time php mylongcommand.php &> dump &
