45.26 Quoted hereis Document Terminators: sh vs. csh

At the times you need to quote your hereis document ( 8.18 ) terminators there's an annoying problem: sh and csh demand different conventions. If you are using sh , you must not quote the terminator. For example,

#! /bin/sh cat << 'eof' Hi there. eof

If you are using csh , however, you must quote the terminator. The script:

#! /bin/csh cat << \eof Hi.  You might expect this to be the only line, but it's not. eof 'e'of \eof

prints three lines, not one.
