Subject: [PATCH 45/89] ps: Provide an option to display no header line
|
||
|
|
|
||
|
|
One might often find it useful to redirect/or filter the output
|
||
|
|
generated by the 'ps' command. This simple patch provides an option
|
||
|
|
(i.e. '-H') to display no header line so it does not need to be
|
||
|
|
considered e.g.
|
||
|
|
|
||
|
|
crash> ps -u -H | head -5
