Hi,
I wrote a ksh program on Unix.
One thing I don't understand: some users run it with different results.
I suspect it's either "cat" or "grep" command.

Basically, with one group of user, the 'cat' or 'grep' command is not getting the data I need and that changed the result.

Is the above the real reason and what should I do with it?

Thanks for your help!

Hi,
I just found out that the ksh program would run sometimes correctly but not all the times for the some users.
Does this mean anything to anybody?

Thanks!

Not much to go on here. Try nailing down the path:

export PATH=/usr/bin:/usr/local/bin

or whatever.
