Re: [tlug] Bourne / bash problem

Here's an interesting work-around that I found.  (Credit to Anon7843, http://unix.derkeiler.com/Newsgroups/comp.unix.solaris/2005-07/0928.html)

$ cat cmts.sh 
#!/bin/bash
echo \
"word1 `echo # comment line 1...> /dev/null` \
word2  `echo # comment line 2... > /dev/null` \
word3  `echo # comment line 3... > /dev/null` \
word4  `echo # comment line 4... > /dev/null` "

$ ./cmts.sh 
word1  word2   word3   word4

Do you think there would be a way to include comments in such a situation?

According to my "Portable Shell Programming" book. These situations will not work with comments:

echo "This will not work."   \<space>
echo "This will not work."   \ # Comment
echo "This will not work."   # Comment   \

The above mentioned book is based around the borne shell (sh) but I don't think that bash changed any rules around comments.
