Shell Programming and Scripting

i am a newbie to unix. I installed cygwin in my windows vista. the terminal has bash as default. I need to work on ksh. the /usr/bin has no vi, clear or any of the ksh commands,

Please tel me the exact link from where i can download vi editor.

Please help.

hmm...

"vi" is not a "ksh command". Both are commands in their own right. Cygwin comes in packages and you manage these with the "Cygwin Setup" isntaller, which is a graphical tool, which lets you select packages to be installed. Somewhere there is a "vi" package, which is probably a "vim" in disguise and there is a "ksh" paackage too.

Be aware, though, that cygwins "ksh" is most probably a "pdksh", which is not completely compatible with a real ksh. In some regards it more behaves like a bash.

I hope this helps.

Hi.

For the version of cygwin on W7 that we use:

Code:

$ version =o ksh vi
OS, ker|rel, machine: CYGWIN_NT-6.1, 1.7.16(0.262/5/3), i686
MIRBSD KSH R40 2012/04/06
VIM vi 7.3

The version command is local to our site.

Best wishes ... cheers, drl

The original AT&T KornShell could be compiled on cygwin as well:

Code:

% uname -sr
CYGWIN_NT-6.1-WOW64 1.7.9(0.237/5/3)
% ksh93 --version
  version         sh (AT&T Research) 93u 2011-02-08

You can download ksh93 binaries for cygwin from AT&T's software download site
