Introduction[edit] Awk reads from a file or from its standard http://stackoverflow.com/questions/8474276/awk-syntax-error-whats-causing-it input, and outputs to its standard output. You will generally want to redirect that into a file, but that is not done in these examples just because it takes up space. awk does not get along with non-text files, like executables and FrameMaker files. If you need to edit those, use a binary editor like hexl-mode in emacs.

Awk operates on one record at a time. A record consists of fields, which by default are separated by any number of spaces or tabs. Field number 1 is accessed with $1, field 2 with $2, and so forth. $0 refers t
