Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Merge PDFs with Ghostscript wrapped in a function

This is an expansion on a previous entry, which I've wrapped in a function and placed in my profile. The "$@" is a positional parameter, much like "$*", but the parameters are passed on intact, without interpretation or expansion; so you can simply call the function like this:

mergepdf *

This will output a merged PDF of all PDFs in the current directory. Alternatively, you can simply list them like so:

mergepdf 00.pdf 01.pdf 02.pdf ...

N.B. Passing a wildcard will merge all PDFs in the current directory in name order, e.g. 00.pdf 01.pdf aa.pdf ab.pdf

Alternatives

There are 6 alternatives - vote for the best!
