Re: How to detect whether a process is running, on Linux, in the manner of 'pidof'?

[Nicholas Joll <nicholasjoll@...>]

Dear all (though here I do think I should not reply to the whole list, 
but an earlier respondent told me that I should, so . .)

    I thank respondents Jeff Pohlmeyer and Marco Ricci.

    Marco Ricci suggested that what I am after is difficult to achieve 
and that probably I should stick to invoking the Linux utility 'pidof'.

    Jeff Pohlmeyer thought that he had a way that I could 
achieve my 
goal in pure lua. Yet, I can't get his code to work. (Here I should 
mention that my lua skills are poor. I have learnt only enough lua to 
implement some system monitoring stuff in it, for Linux - as in the 
present case - and for Windows.) I get the error

   bad argument #2 to 'glob' (no more than 1 argument expected, got 2)

and when I give the function in question a sole argument the function 
seems not to detect as running a process that _is_ running. Perhaps I 
should take Jeff Pohlmeyer's advice after all!

Yours

Nicholas
