Usage: ` basename $0` < -a | -A |-p <program name to filter output> >
|
|
|
|
|
|
Shows swap-usage either for all programs (-a/-A) or filtered for
|
|
a given program name (-p program_name).
|

|
|
|
|
Options:
|
|
|
|
-A
|
|
Show swap-usage for all running processes, even if no swap
|
|
is in use. Not realy useul, but gives a short overview about
|
|
running processes.
|
|
-a
|
|
Show swap-usage for all running processes that have swap space allocated.
|
|
|
|
-p <programm_name>
|
|
Show swap-usage for all processes of the given program name.
