What version of ksh ships with AIX 5.3

aixkshshell-scripting

I'm writing a Korn shell script for a client, who will use it on AIX 5.3. For testing, I'm using version 93u-1 Debian Wheezy. Is this the same version as the one I'll find on AIX?

In summary, no.

oslevel -s

/usr/bin/ksh - Version M-11/16/88

/usr/bin/ksh93 - Version M-12/28/93

The version may differ slightly between different TL/SP levels in AIX. AIX by default uses ksh, and very little uses ksh93. Obviously, you can configure your script to use /usr/bin/ksh93. /usr/bin/ksh93 is provided by the same fileset which provides the other shells (bos.rte.shell).

Ny limit to AIX 5.3 pipe size

You've said you're using ext2, but that's a Linux filesystem. I assume you meant JFS2?

JFS2 and cat both support >2GB files, so I think the most likely thing is the ulimit values - you've put in the contents of /etc/security/limit, but what happens if you run

ulimit -a

as the person executing cat?

If you're actually using JFS, not JFS2, then you'll need to check the filesystem is large file enabled,

Enter smit fs.
Select Add/Change/Show/Delete File Systems.
Choose Journaled File Systems.
Select Change/Show Characteristics of a Journaled File System.
Choose the file system that you are using.
Scroll down until you get to Large File Enabled.

Finally, you can check that you're running the 64-bit kernel, not the 32-bit one, by running the following command as root:

bootinfo -K

That's an upper-case K there. If it returns 32, then you should switch to the 64-bit one.
