Never do it in 'awk' if 'sed' can handle it;
Never use 'sed' when 'tr' can do the job;
Never invoke 'tr' when 'cat' is sufficient;
Avoid using 'cat' whenever possible.

Which I think should be updated to:

Quote:

Never write it in 'C' if 'Perl' is enough;
Never drag out 'Perl' if you can do it in 'awk';
Never do it in 'awk' if 'sed' can handle it;
Never use 'sed' when 'tr' can do the job;
Never invoke 'tr' when 'cat' is sufficient;
Avoid using 'cat' whenever possible.

Shows why I regularly re-read the man pages for the basics: less, grep, cat, etc. , etc. , etc.

BTW, did you know that you can put "#<name_of_command>" as a URL directly into Konqueror's Address/Location dialog box & get the man page in HTML format?

Glad you like my revision.

I have been looking for the right words to capture flavor of the original, this time I think I either got it or came very close. At least close enough to make it public.

Of course then there are Python & Ruby to work in or combine into a high-level scripting class w/ Perl. . . .

It's been 21 months, but I just realized the humor in this:

Let me explain:
Sometimes for clarity I like to break a long pipeline up & put each "joint" of "pipe" on a separate line. This allows the reader to follow the logic step by step. When I do this, I frequently cat the target file into the pipeline, rather than making it the object of the 1st "real" command.

Since this involves using cat w/ only one argument, does this make me a cat abuser?
