ezmlm-tstdig(1)ezmlm-tstdig(1)NAMEezmlm-tstdig - Tests if a digest should be created
SYNOPSISezmlm-tstdig [ -k kbytes ] [ -m msg ] [ -t time ] dir
ezmlm-tstdig reads files in the list directory dir and determines if
any of the criteria specified by the options are met. If they are, or
if all options specified are 0, ezmlm-tstdig exits with success (0).
Otherwise, ezmlm-tstdig exits (99), or in case of errors, (100) for
permanent and (111) for temporary errors.
The normal use of ezmlm-tstdig is to place it in a script so that
ezmlm-get(1) is executed if ezmlm-tstdig exits 0, but skipped other‐
wise.
ezmlm-tstdig uses LOCAL to adapt its behavior so that it can be used
from the command line, a script, or from within dir/editor, or dir/man‐
ager. If invoked from dir/editor, the ezmlm-tstdig line should end in
'|| exit 99'. When used here, ezmlm-tstdig if digest generation crite‐
ria are met tests a timestamp in dir/tstdig. If dir/tstdig is more
than 1 hour old or a digest has been successfully created since
dir/tstdig was written, ezmlm-tstdig will set the timestamp to the cur‐
rent time and exit 0. Otherwise it will exit 99. This is to guard
against initiating duplicate digests when messages arrive while digest‐
ing is in progress.
OPTIONS-k Success if more than kbytes of message body has accumulated
since the latest digest. Defaults to the value in dir/digsize
if it exists or 64 otherwise.
-m Success if more than msg messages have accumulated since the
latest digest. Defaults to the value in dir/digcount if it
exists or 30 otherwise.
-t Success if more than time hours have passed since the latest
digest. Defaults to the value in dir/digtime if it exists or 48
otherwise.
USAGE
This is an example script for ezmlm-tstdig usage.
#!/bin/sh
#usage: script dir diglist@host
#digest if > 64 kbytes message bodies,
# > 30 messages, or
# > 48 hours since last digest.
# ezmlm bin path - modify for your setup
EZPATH='/usr/local/bin/ezmlm'
EZTST="${EZPATH}/ezmlm-tstdig"
EZGET="${EZPATH}/ezmlm-get"
${EZTST} -k64 -m30 -t48 "$1" || exit 0
${EZGET} -t "'$2'" "'$1'" < /dev/null
# improve by testing exit status
BUGS
Obviously, ezmlm-tstdig should be integrated into the digesting program
so that dir/tstdig will not be not necessary. This may be done in the
next version.
