Hi All,
I need to do develop a script in ksh to do the following.
Go to a particular directory (say /opt/alpha)
List files (using ls -ralt)
List the last updated file (ls -ralt|tail -1)
Assign the updated time (only hour) to a variable. (myvar)
eg:
owner group 512 10:22 test_file.log
$myvar should be 10

Appreciate your advise.
Thanks ,
Nish.

Pipe your results through
| sed -e 's/:/ /' | awk '{ print $4 }'
myvar=`ls -ralt | tail -1 | sed -e 's/:/ /' | awk '{ print $4 }'`

Or just for fun, you could do it all with only ls and awk:
integer myvar=$(ls -ltr | awk '{timestamp=$8} END {split (timestamp,timevalues,":"); print timevalues[2]}')
