There is. It would involve ${#var}, which returns the number of chars in
string $var, possibly ${var:n:l}, which returns a substring starting at
position n (zero-based), length l, and ${var#pattern}, which tests if $var
begins with pattern and if so deletes the match and returns the rest
(single hash for shortest match, double for longest) or ${var%pattern},
(same thing for the end).
Untested/unfinished(?) quick hack solution (I took your bait =8^):
echo "-- "
quote=${quotes[$RANDOM_NUMBER]}
# set wrapat as desired
wrapat=72
length=${#quote}
while [ $length -gt $wrapat ]; do
# raw split, not on space
line=${quote:0:$wrapat}
# delete last space +
line=${line% *}
echo $line
# subtract line from input quote
quote=${quote#$line}
# recalculate length
length=${#quote}
done
echo $quote
echo "Homepage - www.wever.org"
echo "Sesam Search Engine - www.sesam.no"
As I said, that's untested, but even if I bugged it, the code should be
clear enough with the comments and close enough to working to hack into
shape yourself, now that I gave you a start.
Note that you have two post-quote lines, so if the quote is long enough to
wrap into more than two lines, you'll violate max sig length netiquette
and get a warning from pan. You could try doubling up the post-quote
lines as I did (tho it isn't needed with the sig I use for this list/group)
with my pre-quote lines to shorten the non-quote sig to a single line,
thus allowing three lines wrapped quotes. The lines total only 58 chars if
I counted correctly, so you have a bit of flexibility in spacing or other
separation, while still keeping the combined line <72-80 chars.
