But thanks all the same... =A0

# rewatch, v. 0.01
#
# Usage: rewatch <n> <cmdline> [process-to-watch]
# =A0 n: seconds between repetitions
# =A0 cmdline: command-line to repeat
# =A0 process-to-watch: process for which "ps aux" info is to be displa=
yed
#
# Purpose: repeat and, optionally, watch and record the "ps aux" info o=
f
# that or any other process
#
# Bkgd: original purpose was to be able to input a command-line (in sin=
gle
# quotes) along with an interval in seconds for its repetion and print =
a
# list of its stdouts labelled by the times they were printed until <Ct=
rl-c>
# is hit, and be able to capture all the output to stdout or a file.
#
# initial use was for watching and recording load averages as programs =
were
# loaded, eg, "re_watch 2 'cat /proc/loadavg' konqueror"
#
# Future: unknown
#
# Known Bugs: no input validation or user feedback for input errors
#
# Of course, bash operators will have to be properly quoted or escaped =
or
# not... -- which i still don't clearly understand
