onstat -c $INFORMIXDIR result
Sergio Peres found that onstat -c shows MSGPATH with an unexpanded $INFORMIXDIR in his bash script. Mike Walker suggested eval or onstat -g cfg MSGPATH, which prints the expanded path. Art Kagel showed a cut-based example. Sergio confirmed Mike's method worked on versions 12 and 14.

Hi,
I have one script that uses onstat results as arguments, on bash I am veryfing one issue.
As INFORMIXDIR appears on some variables they are not resolved by shell
#!/bin/bash
ONLINELOG=$(onstat -c | grep
"^MSGPATH"
)
# This command return something like $INFORMIXDIR/tmp/online.log
grep
"Something"
"
$ONLINELOG
"
returns
grep: MSGPATH
$INFORMIXDIR
/tmp/online.log: No such file or directory
The variables are defined and loaded into the environment, however $INFORMIXDIR appears as a string
I am using CentOS 8.6 and bash 4.4.20
Thanks for any help

#Informix
You will need to expand INFORMIXDIR to it's value in the script. Take a look at the eval command.
Another things is to use onstat -g cfg MSGPATH and grep the value from that output...that usually has expanded the full path already.

Sergio:
It's not complaining about INFORMIXDIR, it is complaining about the arguements to bash on the ## line.
Is this what you are trying to accomplish:
art@Elezar-II:~$ cat aa
#!/usr/bin/bash
export ONLINELOG=$(onstat -c | grep "^MSGPATH" | cut -d\\ -f2)
# This script sets an environment variable for the rest of the session from
# ONCONFIG output from onstat
echo "ONLINELOG=$ONLINELOG"
art@Elezar-II:~$ ./aa
ONLINELOG=$INFORMIXDIR/tmp/online.log

Thanks for reply Art, My problem is that shell do not replace variable for the correct value an dreturns error. Using Mike solution works fine and give teh correct value, I have tested over version 12 and 14 and works on both.
