My snipplet for an if/then/else in shell scripts looks like this:
if true
then :
else :
fi
The colons make that code syntactically complete, w/o the colons you run into a syntax error. The colon is the “null op” of (Bourne) shell scripting.
And the colons usually remain there for the remainder of the life of that code.
Have you noticed, that the youngsters, that talk about snipplets nowadays seriously think, they invented them? True, I guess, they created the term. Just the term.
You do know the result of this:
a=A; echo $a
a=A; b=B; echo $a.$b
a=A; b=B; echo ${a}.${b}
case $var in
x*)
echo var starts with x
;;
*)
echo var starts with something else
;;
esac
case “$var” in
x*)
echo var starts with x
;;
*)
echo var starts with something else
;;
esac
You do know the result of this:
a=A; echo $a
But are you just as sure here?
a=A; b=B; echo $a.$b
a=A; b=B; echo ${a}.${b}
Enclosing variable names in curly braces is quite often a good idea.

One of these milksops told me “the other day”, that wouldn’t be true, and I couldn’t prove him wrong then. It hurts having trusted yet another shameless lie.
MoinMoin offers a web GUI, but not for Google Chrome.
Both are very nice wiki systems with pretty comfortable markdown.
Credos written as profiles.
I have the DocBook XSL book in front of me (opened at “Chapter 31. Website“), asking myself and the world (irc://irc.freenode.net#docbook) silly questions, like the ones, you can find as my recent articles on this blog.
I want to change a couple of pretty raw vanilla DocBook web sites to pretty raw but neat vanilla DocBook Website web sites during the next couple of hours. There is other work to complete pretty soon, so I rather complete this thing now.
I am using docbook-website-2.6.0/example from Sourceforge (look around here!! ((FIXME))) (of course as example-JH-0, so I can always diff to the origin).
Their Makefile-example.txt is now my Makefile, I just had to adapt DOCBOOK_WEBSITE and XSLT:
…
Try this:
$ make clean
$ make realclean
$ make depends
$ make
…
Update / 2010-07-14:
I have made pretty good progress during the last couple of days.
I converted a couple of plain DocBook web-sites (HTML!!) to DocBook Website, and I rather sense some satisfaction there. You can find those web-sites right here in the right column listed as my most exciting web-sites. Sorry for the bragging, but the Website guys did a rather good job, so even me cannot spoil that a lot.
Right, and a web-designer mate of mine will show up on Friday, and we are going to discuss the replacement logos for all the NDW-logos around there. And a very big “thank you!!!” here to Norman for all his good work!!!
I found it at SourceForge.
I really love editing XML in Emacs’s nxml-mode. I did mention that at my DocBook Wiki home page already.
