Yes, well I have it running on HP-UX with a file not found error then the "I am here" bit, but on AIX 6.1, AIX 5.1 (please don't laugh yet) and ...... AIX 4.3.3 I just get the file not found error and the script aborts.
I also inserted
Code:
#!/bin/ksh
as the first line to be sure, but no change. I presume that this is suddenly a good reason to use cat!!!
If I write this in my natural style as
Code:
#!/bin/ksh
fun()
{
cat some_file_that_does_not_exist | while read x
do
echo $x
done
}
fun
echo I am here
...it works fine on AIX too.
Can anyone explain the mismatch?
.... and here's me battling my instincts to avoid a useless use of cat such as cat $file | while code.

Hello,
I am a bit puzzled by the way my shell treats spaces in filenames.
An example will be way clearer than any explanation I can make:
$ ls test\ file\ with\ spaces
test file with spaces
$ var="test\ file\ with\ spaces"
$ echo $var
test\ file\ with\ spaces
$ ls $var

In a Korn shell script I have,
cat ../header | sed -e 's/flag1/$cnumb/g' > header.txt
The header is short
{{Company flag1}}
But the result in header.txt is
{{Company $cnumb}}
The value of $cnumb is 120. I am trying to get the value of $cnumb into the header.
I have tried /'$cnumb'/g,... (10 Replies)
Hi
Don't know if this is a dummy question, but let's give it a try.
I yesterday had a problem with undefined behaviour in the sort shell command (I'm using bash), leading to different sort orders without apparent reasons. I resolved this by typing
export LC_ALL="C"
export LC_COLLATE="C"... (5 Replies)
Hi all,
Can someone point me in the right direction for a manual on the various statement options for 'if'. Basically I have a piece of code which says:

As usual any help much appreciated.. (5 Replies)
Guys, please help! I am currently using an AIX server however whenever I tried to use the typeset -F3, the variable is resulting with a "#".

Hello all. This is my first post/question on this site.
I’m a new Systems Analyst with previous experience with BASH. Although now I'm using AIX, and I’m trying to get a feel for the Korn shell (for those of you that don’t know AIX only uses the KORN shell).
I hope I put this into the correct... (10 Replies)
Hi there.
I'm facing a strange & an intriguing behaviour with sed while replacing the tab character with a space reading from a file. It randomly works sometimes but mostly doesn't work.
Below is what's happening-

perlos400 - Perl version 5 on OS/400
DESCRIPTION
This document describes various features of IBM's OS/400 operating system that will affect how Perl version 5 (hereafter just Perl) is
compiled and/or runs.
By far the easiest way to build Perl for OS/400 is to use the PASE (Portable Application Solutions Environment), for more information see
<http://www.iseries.ibm.com/developer/factory/pase/index.html> This environment allows one to use AIX APIs while programming, and it
provides a runtime that allows AIX binaries to execute directly on the PowerPC iSeries.
Compiling Perl for OS/400 PASE
The recommended way to build Perl for the OS/400 PASE is to build the Perl 5 source code (release 5.8.1 or later) under AIX.
The trick is to give a special parameter to the Configure shell script when running it on AIX:
sh Configure -DPASE ...
The default installation directory of Perl under PASE is /QOpenSys/perl. This can be modified if needed with Configure parameter
-Dprefix=/some/dir.
Starting from OS/400 V5R2 the IBM Visual Age compiler is supported on OS/400 PASE, so it is possible to build Perl natively on OS/400. The
easier way, however, is to compile in AIX, as just described.
If you don't want to install the compiled Perl in AIX into /QOpenSys (for packaging it before copying it to PASE), you can use a Configure
parameter: -Dinstallprefix=/tmp/QOpenSys/perl. This will cause the "make install" to install everything into that directory, while the
installed files still think they are (will be) in /QOpenSys/perl.
If building natively on PASE, please do the build under the /QOpenSys directory, since Perl is happier when built on a case sensitive
filesystem.
Installing Perl in OS/400 PASE
If you are compiling on AIX, simply do a "make install" on the AIX box. Once the install finishes, tar up the /QOpenSys/perl directory.
Transfer the tarball to the OS/400 using FTP with the following commands:
> binary
> site namefmt 1
> put perl.tar /QOpenSys
Once you have it on, simply bring up a PASE shell and extract the tarball.
If you are compiling in PASE, then "make install" is the only thing you will need to do.
The default path for perl binary is /QOpenSys/perl/bin/perl. You'll want to symlink /QOpenSys/usr/bin/perl to this file so you don't have
to modify your path.
Using Perl in OS/400 PASE
Perl in PASE may be used in the same manner as you would use Perl on AIX.
Scripts starting with #!/usr/bin/perl should work if you have /QOpenSys/usr/bin/perl symlinked to your perl binary. This will not work if
you've done a setuid/setgid or have environment variable PASE_EXEC_QOPENSYS="N". If you have V5R1, you'll need to get the latest PTFs to
have this feature. Scripts starting with #!/QOpenSys/perl/bin/perl should always work.
Known Problems
When compiling in PASE, there is no "oslevel" command. Therefore, you may want to create a script called "oslevel" that echoes the level
of AIX that your version of PASE runtime supports. If you're unsure, consult your documentation or use "4.3.3.0".
If you have test cases that fail, check for the existence of spool files. The test case may be trying to use a syscall that is not
implemented in PASE. To avoid the SIGILL, try setting the PASE_SYSCALL_NOSIGILL environment variable or have a handler for the SIGILL. If
you can compile programs for PASE, run the config script and edit config.sh when it gives you the option. If you want to remove fchdir(),
which isn't implement in V5R1, simply change the line that says:
d_fchdir='define'
to
d_fchdir='undef'
and then compile Perl. The places where fchdir() is used have alternatives for systems that do not have fchdir() available.
Perl on ILE
There exists a port of Perl to the ILE environment. This port, however, is based quite an old release of Perl, Perl 5.00502 (August 1998).
(As of July 2002 the latest release of Perl is 5.8.0, and even 5.6.1 has been out since April 2001.) If you need to run Perl on ILE,
though, you may need this older port: <http://www.cpan.org/ports/#os400> Note that any Perl release later than 5.00502 has not been ported
to ILE.
If you need to use Perl in the ILE environment, you may want to consider using Qp2RunPase() to call the PASE version of Perl.
