Effective Commands To Get Time/Size in Bash

Hello All,
Is there an effective approach in Bash to get size of the file and time stamp(including year) on the file. I have below please comment.

SIZE=`/usr/bin/du -sh "${LOCATION}"/"${DATAFILE}" | awk '{print $1}'`
BSIZE=`/usr/bin/du -b "${LOCATION}"/"${DATAFILE}" | awk '{print $1}'`
TIME=`ls --full-time "${LOCATION}"/"${DATAFILE}" | awk '{print $6" "$7}'`


Thank you.

Do you have the stat command installed?

du (sum up the data blocks) takes longer than ls (calls stat() once)
The following does two stat():
Code:
SIZE=`ls -lh "$LOCATION/$DATAFILE" | awk '{print $5}'`
eval `
ls -l "$LOCATION/$DATAFILE" | awk '{print "TIME=\""$6" "$7"\"", "BSIZE="$5}'
`

Hello,
May i know what do you mean "Calls stat once"?
when i did "man stat" it says display file or file system status.
But didn't understand how ls calls stat() once.

Thank you.
