For the Perl script posted by Aia, these files are in a directory structure of 40 different directories. I don't know perl well enough to set up the looping to troll through all of that and test the script. It seems as if I would have to run my script and then call your script and pass $FILE_LIST along with the file with the patterns to remove. Is that right?

Don't know how you get your `wanted' files to process upon. I made it to accept any succession of paths, individually or glob. The only requirement is to pass it first a file containing the patterns to search.
I have run into a problem with one of my patterns, spiro[2,3-dihydrobenzothiazole-2,1'-cyclohexane]
The script doesn't like this because of the unmatched single quote. I have been putting all the patterns in single quotes to deal with special characters. I don't think I can escape this single quote because the strings are single quoted already.
You don't have to escape single quotes inside double quotes and you don't have to escape double quotes inside single quotes.
Choosing whether to use single quotes or double quotes depends on what the strings you're quoting contain.
If you want parameter expansion, command substitution, or arithmetic expansion in your strings, or if you have single quotes in your strings; use double quotes. If your strings contain single quotes or contain dollar signs that could appear to the shell to be parameter expansions, command substitutions, or arithmetic expansions that you want to appear as literal (unexpanded, unsubstituted) character sequences; use single quotes. If your strings don't contain any quotes or dollar signs, single quoting may be slightly faster because the shell doesn't have to look for dollar signs as it evaluates the string.
If you have single quotes and double quotes in your strings, if you want to expand or substitute some, but not all, parameter expansions, command substitutions, and arithmetic expansions; concatenate various types of quoted strings. For instance if you want the string "'" you can use:
Code:
'"'"'"'"'
and to expand one variable and leave another unexpanded:
