Wed Jul 9 16:45:01 IST 2008
Mem Used 744
hddMounted Used Avail
/apps 2.2G 31G


now i need to have the time (16:45) and Mem used (744) tobe extracted and display in timely order

can anyone help me?

cat Jul090000 |grep 'Mem Used' |awk '{print $3}' gives me 744 how to add 16;45 along with this?

Use the same technique to extract "16:45" and put it in a variable. Then use that variable in combination with the other command.

really good AWK tutorial here:
http://www.grymoire.com/Unix/Awk.html

but i have multiple files like this,

To do the same thing on multiple files, you would simply put your script in a structure such as this:

Suppose your script is "wordsmasher", and you have all your files in one directory:

for file in ls; do
wordsmasher $file
<<other commands>>
done

Thanks for your help

You could grab the time like this:

head -1 <yourfilename>|awk '{print $4}'
