Like many in this community, I maintain my notes in text files. I am looking for command line tools that I can use to index and search them.
Are there existing tools that do that? My google skills are are not producing good results.
Thanks

There is a GUI, but it has a perfectly serviceable command-line interface as well. For example, this command lists all files with the exact phrase 'moved permanently':
recoll -t -l '"moved permanently"'
recoll -t -l "ext:py dir:Dropbox/ Import Logging"
And while it's not it's primary purpose, Lucene comes with some CLI programs[2]. They are there mainly as a demo, but if you feel like writing some code you might be able to adapt that to your needs.
If I can piggyback on your question, my notes are in Word files and I sure wish I could grep those. I bet none of the answers at https://superuser.com/questions/70343/grep-in-microsoft-word work any more because Microsoft will keep changing the file format.
Full text search [1] is different from regular expression search.
