Often when running a slow command that writes to a file, I will do
something like
mkisofs -o foo.iso foo & 2>/dev/null
while ls -hl foo.iso; do sleep 1m; done
This generates output like so:
-rw-rw-r-- 1 twb users 1.0G 2007-09-08 20:04 foo.iso
-rw-rw-r-- 1 twb users 1.0G 2007-09-08 20:05 foo.iso
-rw-rw-r-- 1 twb users 1.1G 2007-09-08 20:06 foo.iso
-rw-rw-r-- 1 twb users 1.1G 2007-09-08 20:07 foo.iso
-rw-rw-r-- 1 twb users 1.2G 2007-09-08 20:08 foo.iso
-rw-rw-r-- 1 twb users 1.2G 2007-09-08 20:09 foo.iso
This is useful because I can see look at the recent output *history*
and infer that mkisofs is operating at about 50MB/min.
I guess watch could be made to support such a use case fairly easily
by adding a switch (e.g. --no-clear) to suppress clearing the screen
after each run.
