I want to do something like the following:
#! /bin/sh
cat <<END
I,ve got
a lovely
bunch of coconuts
END
| grep coconuts
The above doesn't work so how can I do it?

Well the last line has no connection to the rest of the script so I am not suprised. I assume you tried putting it on the same line as "END" and saw that there was no effect either. The answer is to put it on the "cat" line like this: cat | grep coconuts << END -- D'Arcy J.M. Cain (darcy@druid) | D'Arcy Cain Consulting | I support gun control.

The pipe symbol (not necessarily the command, but the symbol) must be on the current command line. The current command line is "cat ...". Either of the following will work: cat <<END | grep coconuts ... END or cat <<-END | ... END grep coconuts Note, in the second example, I also used the "-" notation of the here document to allow the document to be indented by tabs. This has no effect on the pipeline and could be omitted. It is a readability issue. Jon -- Jon LaBadie {att, princeton, bcr, attmail!auxnj}!jonlab!jon

Another approach is to use functions in your shell:
(This example works in KSH also)
#!/bin/sh
# create a function to pipe to, if you want
write_it () {
bold=`tput bold`
while read words
do
echo "${bold}${words}"
done
}
#Place the here document inside a function. The results of the function
#can be piped to any process which reads from stdin.
here_cat () {
cat << BYE
This is
the test
of the use
of a HERE
document
in the SH
BYE
}
# Invoke the "here function" and pipe its output to something.
here_cat | write_it

[asks how to pipe a here document to a complicated command.]
Actually, the solution was given in one of the original answers,
but it was among several other solutions so it may have been missed.
#! /bin/sh
# If sh sees a pipe it knows the command is continued
