help with grep and mailx
I have a huge file that I want to grep for the following:

the word "SEVERE" and today's month and date (Nov 16)

I then want to send the results of this grep to someone using mailx, as an atachment.

My question is how can I do this in one single line?


Thanks in advance.

Can you explain the syntax? I tried this and it didn't work, so I'm trying to breakdown each command to be clear what it does.

Thanks

---> testfile is the 'HUGE' file u are mentioning abt ;

----> date | cut -d" " -f 2,3 gives Nov 16

---> grep "SEVERE" is grepping for the out put from prevoius pipe.



---> uuencode and mailx are used to send the file as attachement.

Please let me know what is err u are getting ;

Following is more efficient than previous :


grep -e "$(a=`date | cut -d" " -f 2,3`)|SEVERE" testfile | tee file1 | uuencode file1 file1 | mailx X@Y.com

sry for the previous one ...; it may not work ;


this will work :

grep "$(a=`date | cut -d" " -f 2,3`)" testfile | grep "SEVERE" | tee file1 | uuencode file1 file1 | mailx X@Y.com

Use $(command) or the old `command` but $(a=`command`) is crazy. What do you expect that to do?
