Nohup - UNIX for Dummies Questions & Answers

miwinter · #1 07-21-2006

Hi,

Using nohup it sends output automatically to $HOME/nohup.out - how do I direct this output to another named file instead, so I can run several scripts in the background at once, directing their outputs into individual log files?

Cheers

Check if the user running the nohup command has permissions to write in the pwd.

Quote:

If nohup.out is not writable in the current directory, out-put is redirected to $HOME/nohup.out.

By default, the file will be created in the current directory.

Sorry... I'm wanting to state a named file to direct it to, so I can run several at once. I don't mind if they end up in $HOME, I just need to change nohup.out to be something I choose, so I can run several at once and then it won't end up all garbled in together.

I checked the man page of nohup. Here's what it says:

HTML Code:

nohup.out
           the output file of the  nohup  execution  if  standard
           output  is  a terminal and if the current directory is
           writable.

$HOME/nohup.out
           the output file of the  nohup  execution  if  standard
           output  is  a terminal and if the current directory is
           not writable.

This means that to not have the nohup.out file, you have to redirect the stdout to some file.
Try running the nohup command as:

Code:

# nohup command > /path/to/nohup_logfile 2>&1 &

This will create the nohup log in the mentioned logfile.
