= Introduction =
This note describes setting up a Linux terminal (`bash` and `csh`) on a standard Windows computer.

= Linux on Windows: Cygwin =

The application to be pursued is `cygwin`.

== Setting up Cygwin ==

 1. Download [http://www.cygwin.com/setup.exe `setup.exe` (download)]
 2. Run the app.
  * Check 'download from the internet' so that packages come through from the net.
  * Then 'direct connection'
  * Choose a mirror (e.g. `ftp.planetmirror.com` is in Australia I believe)
  * ''Important:'' the default installation just has a `bash` shell, to get a `c-shell`, you must traverse the hierarchy of packages, and under 'shells' choose `tcsh` (or alternatively, just choose all of the shells.
 3. This should now give a `Cygwin` launch icon on the desktop; clicking it will launch a `bash` shell

This installation has many features already, such as: `ftp, sed, ls, mv, rm, cp` etc. Others can be installed by again hitting `setup.exe` and selecting more from the directory tree as before. 

== Setting up a c-shell config ==
In the home directory of the Cygwin application (to find where this is, type:
{{{
 cd <enter>
 pwd <enter>
}}}
at the prompt), now in this directory, save a simple text file (by using `Notpad` for example) called `.cshrc` (the first dot (.) is important): 
{{{
# set path = (/usr/local/bin /usr/bin /bin /usr/X11R6/bin /usr/local/tools )
set path = ( $path /usr/local/tools )
setenv EDITOR vim
set prompt = '%% '
set notify
# overloaded commands
alias ls	  'ls -F'
alias mv	  'mv -i'
}}}
Not much of this is important except for the `set path = ( $path /usr/local/tools/ )` command since this adds the `/tools` directory to the 'path' of the terminal. The path are the various places that the terminal will look to run programs from. We are going to add certain programs to this area.

The two `set path` variants are given -- the first I use fine on this box, the second is probably better for `Cygwin` since the default path has a heap of stuff in it that is not listed in the first line, best not to meddle. .. `/usr/local/tools` is the directory I use for placing my own important (by hand) or created scripts.
