Question How would I do 2 search & replaces in 1 Perl statement?
Hi All,

The below code successfully tails the logfile.log file and colors every word "ERROR" in RED, thanks to the Perl statement below.

However, would anyone know how to append 1 additional search/replace to the Perl statement below, to color the word "SUCCESS" in GREEN (using ANSI \e[42;1m) ? I'd like to do this without piping to a 2nd perl statement, if possible.

Code:
  tail -f /var/log/logfile.log | perl -pe 's/ERROR/\e[41;1m$&\e[0m/g'

Thank you so much!

(btw- DGPickett, thanks for your help in the other thread...I simplified the code over here to make this question easier to read)

I think this should work for you:
Code:
tail -f /var/log/logfile.log | perl -pe 's/ERROR/\e[41;1m$&\e[0m/g;s/SUCCESS/\e[42;1m$&\e[0m/g'

Hi Bartus,

Wow. A semi-colon was all I needed. My gosh, I could streamline/improve so much of my past script knowing that now. Thank you so much for not only helping me out here, but in giving me a tip that will last as long as I'm scripting!

Thank you!
