Ed
This programming language may be used to instruct a computer to perform a task.

See Also:	Ed on the HOPL

Listed below are all of the tasks on Rosetta Code which have been solved using Ed.

This is the command language used by wp:ed_(software), the line oriented text editor.

Implementations are GNU Ed, Plan 9 Ed, BSD ed, and original UNIX ed. Ed is also a precursor to a whole family of other text editors and command languages. Including Sed, ex, vi, vim, sam, and others.

Ed scripts are usually ran as (on the example of GNU Ed)

cat script.ed | ed -lEGs file.in

Or, more portably, with Basic Regular Expressions on BSD, Mac, and GNU Ed.

cat script.ed | ed -s file.in

There's a convention of starting every ed script with capital H on a line of its own, to toggle more verbose error messages on. And optionally end the script with capital Q to force-quit without saving the changes to file.
