Hi,

This is nothing critical, I just dont like to keep the terminal window open in X.

I tried the command \"sh run_client &\" but it doesn\'t seem to have the effect. When I close the terminal window in X or log off from the tty that I started the process, the client exits. Is there another way to do this?

Thanks,

hako

Hi,

you can try this:

cd BOINC_DIR;
nohup ./BOINC_BIN >/dev/null 2>&1 &

nohup ./BOINC_BIN >/dev/null 2>&1 &

Thanks,
This worked excellently. May I ask two questions though?

  • I read about nohup command but could not understand the argument you used. Would you be so kind to explain what \">/dev/null 2>&1\" argument does?
  • Is there a way that I can start the client this way with liest processor priority (nice +19)?


Thanks again in advance.

>/dev/null sends all the output that would normally be shown on the terminal screen to a linux version of \'nowhere\'.

The ampersands release the terminal from the job (works with any command so you can carry on using the terminal after the job has run). Not sure about the 2>&1.

Not sure about the 2>&1.


\"2>&1\" expression redirects standard error to standard output, and since the latter has already been redirected to nothing (/dev/null) with the previous statement (>/dev/null), that makes both standard output and error redirected into nothingness :) (and your terminal screen free of any messages). The same thing can be accomplished with a single expression (they can both be redirected into nothingness): &>/dev/null
If you wanna know more:
\"man bash\"
\"REDIRECTION\" paragraph
