i have a filename access and i tail the file to grep "MOD" or "DEL" with the below command. tail -f access | egrep -i '(MOD|DEL)' But how can I grep with 'and' condition? I tried below command. tail -f access | egrep -i '(MOD&DEL)', but nothing is returned

In reply to OT: what is grep command for and condition by anakin30
