Download and extract the latest release.
To install, just execute ./install.sh. If you wish to install psgrep
somewhere other than /usr/local/bin, set the $PREFIX variable like so:
PREFIX=/usr sudo ./install.sh
The default $PREFIX is /usr/local
If you, for example, install psgrep to your home directory, don't forget to set
your PATH to include ~/bin as well as your MANPATH (or ~/.manpath) to include
~/share/man.
If you wish to install this as an actual package on your system, you will need
the checkinstall program. General syntax you can follow (just accept defaults):
PREFIX=/usr sudo checkinstall ./install.sh
For example, on my Debian/[K]Ubuntu-based system, I could run:
PREFIX=/usr sudo checkinstall -D -A all --gzman ./install.sh
