Hello,

Is it possible to "compress" the contents of a text file? I have a log file with a lot of recurring computer names. I would like to know if I can shorten that list so each recurring name turns into just one name.

For instance, here are the contents of my file:

I would like to shorten the file to look like this:

Is this possible?

Thanks for any input!

you might to try this:

Code: Select all

@echo off

type nul>new_source.log
for /f "tokens=* delims=" %%a in (source.log) do (
findstr "%%a" "new_source.log">nul || echo %%a>>new_source.log
)
