Do not setup SIGHUP signal handler if we are in the batch mode
|
||
|
|
|
||
|
|
Top enables a signal handler for the SIGHUP signal (loss of terminal). While
|
||
|
|
this makes sense for top's default interactive mode, it doesn't make any sense
|
||
|
|
for batch mode. If you run top in nohup just to collect data over time and
|
||
|
|
disconnect top finishes which is not what one would expect.
