function atomuitail(){
tail -f $1 | awk '
/MEMC/ {print "\033[32m" $0 "\033[39m"}
/DEBUG/ {print "\033[32m" $0 "\033[39m"}
/ERROR/ {print "\033[31m" $0 "\033[39m"}
/error_message/ {print "\033[31m" $0 "\033[39m"}
'
}
Add above function to your .bashrc / .bash_profile. Easy to mark errors. Saves a bit time to search for errors(Without Grep). Below attached a screenshot of my terminal. Hope it helps.
