KornShell 93

KPS — Thu, 05 Jul 2007 12:03:28 GMT

Has anyone heard of KornShell 93 and if so have you installed it on HP-UX? I'm getting a request by one of the Developer Type folks to install this, but I'm not aware of any harm this would do if any on HP-UX 11.23? (IA-64).

Any help would be greatly appreciated...

Hi:

Yes. The Korn shell released with HP-UX is Korn-88. You can find an enhanced version (Korn93) in '/usr/dt/bin/dtksh'.

Much Appreciated!

Just a caution. Resist the temptation to replace /usr/bin/ksh with the contents of dtksh. There are enough differences with ksh93 syntax to make some scripts misbehave. Just make the first line of ksh93 scripts:

#!/usr/dt/bin/dtksh

and all will be well. Note that if the developer wants to make this their login shell, tell them to use this command (root capability not necessary):

chsh someuser /usr/dt/bin/dtksh

Just Enter
# ksh -o vi
and then
. /.profile
you will be in korn shell.

Thnaks,
