Interesting...

How much do you want for your stash of quotes :)

 That one, as it said in the message, was from Eric Scott Raymond. I
like collecting pithy, funny, or profound quotes. I currently have...
let's see... 437 of them. I have a little script that randomly picks one
for each message. Actually, it's interesting in a Unix sense how I do
it.

 Most Unix email and news programs will read a 'signature' from a file
called ".signature" in your home directory, if it exists. I don't have a
file there, I have a "fifo". On Unix, you can have a 'named pipe', or
'fifo' (First In First Out) that programs can read from and write to.

 When a program reads my ".signature", they don't get the contents of a
file, they get whatever a program at the other end of the fifo feeds to
them. I have a script called "fifosig.sh" that does the selecting,
picking a random signature and squirting it through the fifo to whatever
program reads from the other end.

--------fifosig.sh--------
#!/bin/bash
while true
do
 # The low-order bits of a PRNG are often not terribly random,  # but
this is good enough.
 SIGGY=$((RANDOM % `ls -1 ~/News/sigs/msig* | wc -l`))  cat
~/News/sigs/msig$SIGGY > ~/.signature 2> /dev/null  sleep 1 # Some
applications need this 'rest'...
done
--------------------------

 So, I get randomly-selected quotes by default. Sometimes, when I have a
particularly apt quote I remember from my collection, I overwrite it by
hand, but usually I let chance rule.

 Sincerely,
