Earlier I asked about testing if a file exists csh scripts and I was
convinced to use sh for programming. One problem I have is with
substitution of a commands output and testing the resulting value in the sh
syntax. E.g.
I want to process files that start with someprefix a period followed by two
digits (just for an example). I couldn't get this to work in the sh syntax.
in csh:
if (`cat $file | egrep 'someprefix\.[0-9][0-9]$' | wc -c` > 13) then
in sh:
?
