Script Question

[Hunki]

The attached script is failing on hosta while runs fine on hostb.

The set -x output on hosta gives the following output :

+ + date +%G-%m-%d
cdate=2007-02-19
+ + date +%H
chour=10
+ + date +%M
cmin=56
+ dated=2007-02-19_1056
+ uname -n
+ [ hosta = hostb ]

and comes back to the command prompt . The shell is ksh. Please help.

To troubleshoot this issue could you execute the following script on hosta and post the output here:

#!/usr/bin/ksh -x

if [ `uname -n` = hostb ]
then
echo "not on hosta"
else
echo "on hosta"
fi

[Hunki]

+ uname -n
+ [ hosta = hostb ]
+ echo on hosta
on hosta

Try to break down the script into smaller parts in order to isolate the problem. Look inside the block of statements that get executed if the condition is true; do the same for the commands that get executed when the condition is false.

~hope it helps

Run the attached script and post the output of the set -x run. I inserted echo commands to aid in troubleshooting.

Hi,
try:
if [[ $(uname -n) = hostb ]]

the improvment is using double [.
The $() is only good practice.

HTH,
