What I need is a program or routine in [...] If you can find the source to the Unix 'egrep' command, that might be what you are looking for. Here is something I snipped out of the man page for grep on our system: "DESCRIPTION Commands of the grep family search the input files (standard input default) for lines matching a pattern. Normally, each line found is copied to the standard output. Grep patterns are limited regular expressions in the style of ex(1); it uses a compact nondeterministic algorithm. Egrep patterns are full regular expressions; it uses a fast deterministic ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ algorithm that sometimes needs exponential space. Fgrep patterns are fixed strings. The following options are recognized." _. --Steve ._||__ DISCLAIMER: All opinions are my own.
