Well, you asked for comments.
/bin/sh makes it a shell script, not a bash script.
The 1-line version (commands seperated by ; ) comes handy if you need to
get several commands into one line, e.g. for
- creating an alias
- repeating an operation by stepping through bash history
- cron jobs (but know *which* shell is run by cron demon !)
- wrappers (higher languages that make a system("cmd1 ; cmd2 ;...") call
- anything else I forgot
I don't understand your cat vs. echo discussion? --and how that plays
with the maildir system (which I don't use --I'm 'on' mbox). But in
general, cat prints the 'items' in one sequence to stdout whereas echo
lists them (more like 'ls' but with some differences. --just go and play
with both). So if the 'item' is a sub-directory, and not a file cat
presents you with binary garbage, not the files inside the directory.
To avoid a 'useless cat award' from Joseph you want to check if dspam only
reads from stdin or if it has an option to take file names instead.
I don't know, but as one blogger said:
"The documentation for dspam is almost non-existant."
My 0.02 euros -- I bet when the veterans wake up you'll get more
substantial feedback :-) ...................hORST

Subject: [Eug-lug] spam maintenance scripts
I want to:
- Get all mail reported as spam and feed it to dspam to learn as spam
- Get all mail reported as ham and feed it to dspam to learn as ham
- Purge my known spam folder of spam older than 7 days
I've been doing this manually about once every couple weeks. I figured it
was time to write some scripts to do this nightly.
Here's a bash script I came up with. Before I set this loose I thought I'd
ask if the syntax here looks correct. I replaced the cat $i lines with echo
$i and things looked ok, but I'm used to seeing these on the command line
with semicolons between each part... eg:
for i in * ; do cat $i | dspam ... ; done
Thanks for any comments. :)

#!/bin/sh
SPAMDIR="/home/rob/.maildir/.zReport-Spam/cur"
HAMDIR="/home/rob/.maildir/.zReport-Ham/cur"
# Learn Spam
for i in $SPAMDIR/*
do
cat $i | dspam --user rob --class=spam --source=error
done
# Learn Ham
for i in $HAMDIR/*
do
cat $i | dspam --user rob --class=innocent --source=corpus
done
# Purge SPAM folder of messages older than 1 week
find ~/.maildir/.SPAM/cur -mtime +7 -exec rm {} \;
