hi zaxxon,
thanks for hint using "fgrep -f 1.txt 2.txt" it saves me so much time. just now the original script by using grep took me 10mins, now just 2,3 seconds.
:eek: amazing

"grep -F(upper case)"; cannot get the result.

assume 1.txt has 33k lines, 2.txt has 20k lines (each line has many many fields)
if "grep -f 1.txt 2.txt", it took me 5 mins to get the result, but if "fgrep -f 1.txt 2.txt", it took just a second...

:eek::
the script by using grep need more than 5 mins, but fgrep takes just 1 second :eek:: still cannot believe fgrep is so fast than grep.

ha~~~ :eek: so simple!!!
Thanks
