[FAQ] PATH surgery

[Helmut Jarausch]

Hi,

what's the simplest way to do some surgery on the PATH environment 
variable. While vared is interactive I'll need to

- split / join the PATH into an array of PATH's components
- remove the first or any given component
- search for a component containing a given string

Many thanks for a hint,
Helmut.

$path is an array that's tied to $PATH. So basically, the splitting is
done for you already. The two parameters are updated with the other.

You could remove entries like this:

path[1]=()
path[-1]=()

or even

path[(re)/home/foo/bin]=()
