Re: [LAU] another scripting question

Hi Dave,

the command would be:

ps -A | grep jackd

If the output is null, there's no jackd process running. Else, there is
some information-output about a jackd process

24131 ? 00:00:00 jackd

Assign the command to a variable and use an if-statement with something
like...

if $myvariable="" ...

that should do the job....
