2.10. sed

Sed it the streaming editor. It makes it easy for example to replace specially marked texts inside a source code file. The Ethereal build process uses this to stamp version strings into various places.

2.10.1. UNIX: sed

Sed is available for most of the UNIX-like platforms and as the sed package from the Cygwin setup.

If sed isn't already installed and also not available as a package for your platform, you can get it at: http://directory.fsf.org/GNU/sed.html

After correct installation, typing inside the bash:

$ sed --version

should result in something like:

GNU sed version 4.0.9

However, the version string may vary.

2.10.2. Win32 native: sed

A native Win32 sed package can be obtained from http://gnuwin32.sourceforge.net/. The installation should be straightforward.
