My OS is Linux (kernel 4.08.something) and AIX (7100-04-01-1543), the used ksh versions are:
ksh88: Version M-11/16/88f (AIX)
ksh93: Version M 93t+ 2009-05-01 (AIX), Version M 93u (Linux)
When writing a parser for stanza files in ksh i encountered a rather strange behavior. Here is a stripped down version of the parsing loop (i left out the actual parsing for clarity if anyone is interested i can post it), i marked the two critical lines in bold:
Code:
#! /bin/ksh
typeset chLine=""
typeset chChar=""
while read chLine ; do
print - "-- Begin Line: $chLine"
while [ -n "$chLine" ] ; do
chChar="${chLine%${chLine#?}}"chLine="${chLine#?}"
print - "\n Line: \"$chLine\""
print - " Char: \"$chChar\""
done
done < /iput/file
exit 0
Here is the output of this with the sample file (1 line) containing item=value, which works as expected:
Now, because i wanted to have comments in my stanza files (which the parser should filter out), but needed to make escaped comment chars possible i tried with the line item=val\\#ue. Here is the output running above script with with ksh88, which is as expected:
If have
var='$variable'
how can I expand $variable.
I have tried many thing like duble quotes/braces etc, but nothing worked.
I need the solution ASAP. (2 Replies)
Any means of running ksh93 in a ksh88-mode?
Might sound odd, but I want/need to restrict U/Win-developed scripts to correspond to the ksh88 version on my Solaris environment(s). Thanks. (2 Replies)
Hi,
I have a script that calls an external program to perform some calculations and then I read with "grep" and "sed" values from the output files. I've noticed that performance of KSH93 degrades with every iteration. The output files are all the same size, so I don't understand why after the... (2 Replies)

I have tried using awk -v and all sorts of variations but I have hit a brick wall. I have spent a full day on this and am just going round in circles.

Hi Experts,
I have several shell scripts that have been developed on a Linux box for korn ksh93.
If we want to run this software on an AIX 6.1 box that runs ksh88 by default can we just change the she-bang line to reference /bin/ksh93 which ships with AIX as its "enhanced shell" to ensure... (6 Replies)
Hi everyone !
