So, if one line contains both 'word1' and 'word2' and you grep for both the words, you want the same line printed twice each on a new line?

grep for words in file
Hi

No, if two words are on the same line, they can be shown on the same line, but grep finds one word on a line, it should show on a new line.
The ideia is after find the words, use mailx to mail the lines found, but on my outlook I am getting everything in one line....

regards

If your input files is having a valid and contains newline character after each line, you getting probably getting the new line at destination.
It might be the client ( outlook ) or the encoding system which doesn't display it properly.


About your problem, how do you want to grep for the patterns (is it OR or AND between the patterns)?

Also, tell us the OS version on which you are working. and post the sample data and required output.

Hi

Tarun Agrawal

Your suggestion is working fine, but what do I change to show me the last 20 lines only.

The O.S. is hp-ux, the file is /var/adm/syslog/syslog.log
