Command line argument constraint

Rajin43 — Tue, 06 Aug 2013 05:59:52 GMT

Hi All,

I am just trying to execute a long command in HP-UX where i could get it.

it is being ended with < symbol at the last and i could not edit further

Can you help to understand why i am getting like this. (Note : this is happening only in sh shell, in bash shell i am able to run the command without any issues)

Regards

Rajini

While you can have a command line at least 1 MB long, in a real shell you can only edit commands less than 256 bytes.

So all long command lines should be put into a script.

(Or you need to type them without mistakes. :-)

Hi Dennis,

But the same command can be executed using the bash shell in HP-UX.is there any limitations in the shell or do we need to change any settings to run a long command in HP-UX?

(I assume you meant edited.) The shells are different. Same as vi and vim.

>is there any limitations in the shell

Yes, this is one of them.

Hi,

Is there any way to rectify it?

You're not going to get a different answer.

You could put long strings into variables and use those to shorten the lines.

Again, as long as you don't edit the line, you can type as long as you want.
