shell script + match MAJOR and CRITICAL strings from log file

Question

I need to match lines that have MAJOR and CRITICAL strings

that comes after the word ERROR:< any integer number >

please advice how to do that with one awk or sed command?

  more HW_Log.txt CHK_HW             ERROR:0  INFO         self_monitor     Verifying HW machine 
 CHK_HW             ERROR:1  MAJOR        self_monitor     Verifying HW machine 
 CHK_HW             ERROR:1  CRITICAL     self_monitor     Verifying HW machine

Answer

This can be done using grep like:

$ grep "ERROR:[0-9]*  (CRITICAL|MAJOR)" /path/to/file
