My apologies, I didn't realise you were talking about the invalid escape
sequence. Thanks for letting me know about the fact that it's deprecated, I'll
definitely be keeping that in mind going forward.
In a bash shell with the find command available, run the following command:
find . -type f -exec ls {} \;
You should see a list of files.
If you run this:
find . -type f -exec ls {} ;
You should see an error message from find:
"find: missing argument to `-exec'"
If I pass the first example in this message to shlex, I get no indication that
the user attempted escaped the semi-colon in their input.
