UNIX sort by multiple columns

Sometimes the "obvious" stuff isn't so obvious (at least to me...)

I had a text file with multiple columns of numbers. I wanted to sort it by the first column, then the second, then the third. It wasn't immediately obvious to me how to do it. The man page for 'sort' of course does not mention that you can specify the '-k' option multiple times, and I didn't have the GNU 'info' utility installed:

sort -k1n -k2n -k3n file

command-line edit foswiki topics

We use foswiki at SDO for our "Local Operating Procedures" (LOPs). These many consist of numbered steps, with some metadata attached.

I recently was tasked to add a document number to the metadata. Easy, except with hundreds of documents, I didn't want to do this manually.

Each Wiki topic is a text document. The text document also stores the metadata (like the document number). Of course, since it's text it is easy to edit and script the edit with perl.

However, each topic text file also has an associated RCS file for versioning information. If you just edit the text file, the web page itself looks fine, but you can't see the change you made in the page's history (unless you make another change using the web interface).

But it turns out to be very easy to record your direct text file edits in RCS. Simply do

rcs -l TextFileName.txt
## now make your changes using whatever method (manual, scripted, etc.), then:
ci -mnone -t-none -wusername -u TextFileName.txt

That's it! Now the edits you made from your terminal are visible in the topic's history.
