[vdr] Re: vdr Restarting Tool (cron Job + Perl)

[Carsten Koch <Carsten.Koch@icem.de>]

I wonder why this is such a big deal and why perl is required.
On my machine, the following one-liner (from the tcsh prompt)
works:

if ( `ps -e | fgrep vdr | wc -l` > = 6 ) echo vdr running.


One could even extend that and use it to determine if vdr is
busy recording or cutting something:

if ( `ps -e | fgrep vdr | wc -l` > = 7 ) echo vdr busy.


So, for your current problem, I guess all you need is a

if ( `ps -e | fgrep vdr | wc -l` < 6 ) "command that restarts vdr on your machine"
