I have a program I've been using for years that I really like called
envv. I put it up at http://logsoft.com/steveo/envv-1.2p4.tar.gz It's
nice. It's written in C, has a man page and it works well.
The way it works is that I set my PATH variable in a seperate file
called ~/.bash_path
As you can see, envv takes a command, like add or delete, and a
directory path and a possible position. Then it produces as output a
string that if executed will set your PATH variable the way you want
it.
Just make sure that your default PATH is enough to locate where envv is.
# System wide bash_path file. This is used to set up the global PATH variable.
function i_check_exist()
{
if [[ -d $1 ]]
then
eval `envv add PATH $1 $2`
fi
}
sav=$SHELL
export SHELL=/bin/bash
i_check_exist . 1 # Put it first.
i_check_exist ~/bin 2 # Put it first.
i_check_exist /usr/games # Put it last.
i_check_exist /usr/local/office52 # Put it last.
i_check_exist /usr/local/jdk/jdk1.2/bin # Put it last.
SHELL=${sav}
unset i_check_exist sav
# Local Variables:
# mode: shell-script
# End:
