hi,

how do we make a user-defined function in bourne shells to be able to
take it's input(s) from either it's argument list or a heredoc?

For example,

func1() {
printf '%s\n' "$@"
return 0
}

func1 "$var1" 'arg2' # works fine when arguments provided
# by means of shell variables or hardcoded strings

# but this doesnt work
func1 << EOF
this is some heredoc
usage: FOOBAR tmpdir tmpfile codename
EOF

Regards,
Rakesh

if [ "$#" -eq 0 ]; then
cat
else
printf '%s\n' "$@"
fi

}
