Procmail: "Error while writing to..." bash script
My .procmailrc pipes certain messages to a bash script that just certain
sound files based on the arguments passed. The script doesn't read
I noticed lots of "Error while writing to..." in the procmaillog, and
the manpage says this means can't write to file or pipe terminated
So, I added a "cat - > /dev/null" line to the script and the errors
stopped. I have two questions:
(1) Can I count on procmail always writing at least one byte to my stdin
so the script won't hang?
(2) Can you think of a more elegant solution to "throw away" all of
stdin without hanging if its empty?
