I had no idea about the command 'tops', which performs batch search and replace operations on text files. It seems much more accessible to me than other similar tools.

A new cross-platform text editor. Though it is still in alpha with a few inevitable rough edges, this seems to have a lot going for it. In many ways, it combines the best features of Vim with those of Textmate. The 'Goto Anything' feature, and the way selections are handled are particularly nice. I'm on a Vim jag at moment, but I'll be watching this with interest.

A good introduction to some useful features of awk. I don't use Unix tools like this nearly as much as I could/should.

A simple but useful service to save and share bits of text online. No sign-up or logging in involved, though you can choose to password protect your snippet.

This looks like an amazing utility, giving very comprehensive conversion of text from/to a myriad of different formats.
