export command is not working

[Yarok]

Hello,

On HP-UX b.11.11 (C-8000), I try to run export command i.e export TERM=vt100.

Please advice,

Yaron

so whats not working then?

if you set a TERM environment variable as you showed, it just sets it in the current shells environment - it won't actually change anything - what are you expecting to happen? Maybe change the settings for the terminal? If so you should run the "tset" command after setting the environment variable...

export TERM=vt100
tset

The export command should be working 11.11. Please post the error message here

[Yarok]

even if I try: man export it says " no manual entry for export "

[Yarok]

error message:

export: Command not found

export is not actually a command, it is a shell built-in for the sh and ksh shells...

I gues you are using another shell such as csh or tcsh which doesn't have export... why you would want to use these terrible shells I don't know, but the equivalent to "export TERM=vt100" in csh would be "setenv TERM vt100"

As Duncan said, try "man ksh" or "man sh-posix" and look for "export".

Usually, I uses tcsh or sh shells.

1. How can I know what shell Im running with (I mean, is there any command that displays the shell)?

2. what are the benefits of ksh over others tcsh or sh in my case?

BR,

export works in sh/ksh, bash, etc

>1. How can I know what shell I'm running?

Typically you would just know. :-)
You can "echo $SHELL" but that's your login shell and can be changed.
I've found that if you try to execute a bogus command, the name of the shell is mentioned.

There is something terribly wrong if you mention tcsh and sh together, since they don't get along. :-)

Basically sh/ksh are nearly identical and are real shell.
tcsh is derived from the scummy C shell.

Many thanks, I followed the links and informed myself (some with mine old thread :))

BTW, I probably type tcsh to get a comfortable env, so I couldn't run export.

BR,
