Calling awk from csh

I am trying to call awk from a csh script using

awk '{print $1, -$2, $3}' $fvmod.vel > $fvmod.xzv

and getting awk: Command not found.

Running

awk '{print $1, -$2, $3}' $fvmod.vel > $fvmod.xzv

on the command line with the actual filenames works

Did you change $PATH variable during execution of that script?

Yeah, forgot I did that.

Thanks
