macOS How do I extract all words which use a certain character from a text file ?

Most text editors have a "find" function where you can search for anything containing any number of letters.

Assuming you are in the correct directory containing the file, the file is called file.txt and you want the list of words in output.txt then this will do it (without correcting for caps/non-caps). We are searching for c. If you want to search for $ you might well have to escape it

What is the special character? $ or something else?

Thank you so much, you saved me good amount of searching. I finally had to replace the special character to do the task quicker. I tried to escape it with single and double quotes but it didn't work.

$ is a special character in regular expressions (end of line). I generally escape it like this \[\$]. The backslashes are probably overkill.

I don't know if 'special character' is the right expression, I just wanted to extract those.

What character are you wanting to extract the words containing?

Convert each word to a line, and use sed: http://unix.stackexchange.com/quest...between-sed-on-mac-osx-and-other-standard-sed
