ISO UNIX Tutoring in Regular Expressions

Hello all- New to this forum, and relatively new to using grep at the Terminal command line to work with regular expressions. I've got a background in mathematics and some programming experience, so it's not been too difficult to learn the basics of searching through word lists for particular types of matches.

Now I've got a trickier piece of code that I don't know how to write, and I'm struggling to teach myself with the available online resources. I could greatly benefit from a few hours of in-person tutoring from an expert. Is this the appropriate place on this forum to post a call for a suitable tutor in my area?

I live in Queens, New York City. I imagine one afternoon might be enough to have my main questions answered and get me going on my own from there. Open to cash payment or to bartering for skills or artwork (I'm an artist).

Please be in touch if you are interested or know someone who might be. And of course if there is a better place on the forum to post this, I'd appreciate being directed that way.

All best-
Dominick T.

NAME
grep - search a file for lines containing a given pattern SYNOPSIS
grep [-elnsv] pattern [file] ... OPTIONS
-e -e pattern is the same as pattern -c Print a count of lines matched -i Ignore case -l Print file names, no lines -n Print line numbers -s Status only, no printed output -v Select lines that do not match EXAMPLES
grep mouse file # Find lines in file containing mouse grep [0-9] file # Print lines containing a digit DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1 occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is returned. SEE ALSO
cgrep(1), fgrep(1), sed(1), awk(9). GREP(1)
