h (hhighlighter is just a name to help search engines) is a really tiny helper script meant to highligt keywords in the output of another linux command:

h is just a tiny facade in front of ack so you need to install it first.

What is ack?

ack is a tool like grep, optimized for programmers

Designed for programmers with large heterogeneous trees of source code, ack is written purely in portable Perl 5 and takes advantage of the power of Perl’s regular expressions.

ack installation

ack is part of many major linux distributions so you should use your package manager to install it.

see: http://beyondgrep.com/install/

If you want to install ack in a portable way ( at the end ack is just a script ) you do it in this way:

curl http://beyondgrep.com/ack-2.08-single-file > ~/bin/ack && chmod 0755 !#:3

h is imlemented as a function in bash.

You can install it in one of these ways:

• copy and paste h() function in you ~/.bashrc

• configure your ~/.bashrc to load the external script with . /path/to/h.sh

h has currently been tested only on bash and zsh on Linux.

h is meant to consume the output of another linux command via pipe

echo "abcdefghijklmnopqrstuvxywz" | h a b c d e f g h i j k l

or

tail -F | h keyword1 keyword2

or

mvn clean install | h FAILURE SUCCESS
