Shell differences HPUX / SOLARIS

HI,

What is the base shell on HP servers ( bourne, korn or Posix ) ??
We have a SUN server and i would like to have the same shell on it,so that my scripts and commands ( originaly on HP ) can work.

ex : ll or Esc - for history commands

Thank's

Posix would be your best bet.

Hi:

The Posix shell is the default shell for HP-UX and is found as '/sbin/sh' (staticly linked) or '/usr/bin/sh' (dynamically linked).

See 'man sh' for more information.

Regards!

You can use the same shell in both OSs if you are a normal user. You cannot use the same shell has root. Trying to do so will make one OS or the other unbootable.

Hi,

for users you can use the korn shell on both systems, but you still see some differences...
e.g. on HP-UX you complete filenames with ESC ESC, but on Solaris you'll have to type ESC \ or even ESC *

Sorry,
Wodisch

Actually, Solaris's default shell is Bourne if I remember correctly and is called /usr/bin/sh. In HP-UX, /usr/bin/sh is the POSIX shell and (AFAIK) does not exist on Solaris. The POSIX shell from HP is an almost proper superset of Korn (ksh) which is a Posix-compliant shell, just like Bash. If you want the Bourne shell in HP-UX, it's located at /usr/old/bin/sh (but use of the Bourne shell today is deprecated)

The the vast majority of scripting requirements, the POSIX shell in HP-UX is virtually identical to ksh. But since Solaris's sh is not Posix compliant, I would use /usr/bin/ksh and it will run on both. (note that like HP-UX, Solaris no longer has /bin, it is a link to /usr/bin).
