I log into a lot of client production servers and do not have the luxury of installing my favorite GUI tools, such as UltraEdit, which (among other things) easily allows me to search within files. On these servers I am limited to what is already installed. Just today I was forced to search an entire website on a client server for a file that that might contain the string “bill”.
So I turned to my trusty DOS skills and utilized the little-known findstr command. I typed in my command, piped the output to a text file, and viola! I had my results and quickly found the file I was looking for.
FINDSTR /S /N /I /C:”bill” * > find.txt
I was looking for a literal string (/C:) “bill” in all files (*) in all sub directories (/S), without case-sensitivity (/I), outputting the line number the match was found in (/N) and outputting it all to a file instead of the console (> find.txt).
FINDSTR is really quite useful if you have no other tools available to you.
