If a file named /abc/xyz/joesfile there only your file size will be there. Else it is none there.
To make more efficient then,
[[ -f /abc/xyz/joesfile ]] && filesize=$(ls -s /abc/xyz/joesfile | awk `{print $1}`)
It will give the size when the file /abc/xyz/joesfile must be there. Else it will not assign file size there.
