Plurrrr

These are my stupid unix tricks. I hope that they are useful to you.

If you’ve spent any amount of time at a Unix command line you’ve probably already seen xargs. In case you haven’t, xargs is a command used to execute commands based on arguments from standard input.

If you need to parse a language, or document, from Python there are fundamentally three ways to solve the problem:

• use an existing library supporting that specific language: for example a library to parse XML
• building your own custom parser by hand
• a tool or library to generate a parser: for example ANTLR, that you can use to build parsers for any language
