I said "as a starter", not "for starters", but anyway, you are problably
right. The syntax for the expiration date in the files was just "use the
number that can be found in the same line as the 'expires' string". To
actually implement the syntax in Jim's original mail you use
1> #!/bin/bash
2> # echos all names of files that have expired
2a> #removes all files that reach their remove-date
3> now=$(date +'%Y%m%d%H%M')

9> [ "$removes" -a "$removes" -lt "$now" ] && rm -f "$i" && break

1'> done | uniq
This will find all occurences of Expires:<date>; and Remove:<date>;
rules and act accrdingly, except when an expires tag is given on a line
that precedes the line with the remove tag and both are older than $now.
In this case the filename is printed (indicating expiration), but the
corresponding file has been deleted.
You could split the script into one that removes files and one that
prints expired files. Or you could hack l.1' to become
1'> done | uniq | while read; do [ -f "$REPLY" ] && echo "$REPLY"; done
which is IMO ugly, but Unixish :-)
