"dog" is also a command - it's an improved version of "cat", similar to
how "less"[*] is an improved version of "more" - albeit that it's not
installed by default on most systems. ;-)

[*] There's also an improved version of "less" *and* "more",
called "most". :p Gotta love those GNU hackers. ;-)

Time to renew my C skills - "mostly" an advanced version of "some". (skips
every 5th line on average) :-)

I'll leave it to the newsgroup to debate "less" versus "fewer"...

for years i've been using a sleazy local script, dog,
to strips '#' comments out of text data files:

$ cd /usr/local/bin
$ cat dog
#!/usr/bin/sed -f
/^[ ]*#/d
/^[ ]*$/d
s/[ ][ ]*#.*//
$ dog dog
/^[ ]*#/d
/^[ ]*$/d
s/[ ][ ]*#.*//
$

You might improve that script by changing the operation order:
eat comments, eat trailing whitespace, eat empty lines?

Thanks, Grant - as always, good Clue from you :*)
I'll update my local script package accordingly.

I'm not much a fan of sed (prefering awk) and didn't write that,
but it works okay, mostly, so I just use it.
