Re: grep: -i option not working i cronjobs

[J. W.Andersen, Falster System Teknik]

Julian -

I took a look at the sources, and sad to say, I have to admit my 
inabillity to find out how the program
really works - undoubtedly it has been written by some very bright 
people, and I obviously do not
belong in that category - at least not anymore, and, compared to my own 
earlier C productions, I find
it rather sparsely commented, so I think, it will be in everybodys best 
interrest, that I keep
my dirty fingers out of it - I can probably only make things 
considerably worse.

The good news is, that I found a workaround: Use fgrep instead, that 
seems to work with exactly the
same options - also in cronjobs. Maybe you can use that info in your 
grep troubleshooting, at least on
a comparative basis. However, I could kick myself, that I did not try 
that days ago.

Thanks again for your time and good work with GNU.

Joe.-
