/usr/bin/time -f'%e' [ -e /mnt/mynfs/somefile ] That will return the "real time" in seconds. I'm using the absolute path '/usr/bin/time' because time is also a Bash built- in; you'll need to install the "time" package if not already so. It might happen that due to caching `[ -e /mnt/mynfs/somefile ]` returns fast even if the NFS mount point is clogged, reading a file might be better: /usr/bin/time -f'%e' cat /mnt/mynfs/somefile > /dev/null Cheers. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
