how to remove particular path in cygwin

Question

I want to ask how to remove path in cygwin. Let's say I have 3 paths:

PATH=path1:path2:path3

I want to remove path2 so it will be:

PATH=path1:path3

But actually i have a lot of path inside and it will painful to rewrite it manually. Any suggestion?

A simple solution is to use the bash or csh command-line:

   export PATH=`echo $PATH | sed s/:path2//`

But this will only work 99.9% of the time. To handle the edge cases, such as when path2 is at the start, or when it is part of another path, you'll need:

   export PATH=`echo $PATH | sed "s/:path2:/:/g;s/^path2://;s/:path2$//"`

i got this when echo $PATH, "echo $PATH | sed/:PHP/xampp/" :D – kreamik Feb 26 '13 at 09:19
@kreamik: I am sorry, but I do not understand. Perhaps by `sed/:PHP...` you mean `sed s/:PHP...`? – Joseph Quinsey Feb 26 '13 at 09:26
What shell are you using? (I think cygwin defaults to `tcsh`, but I might be misremembering.) – Joseph Quinsey Feb 26 '13 at 09:29
i type "which bash" i got "/usr/bin/bash" – kreamik Feb 27 '13 at 01:41
