Hi,

Is there any way to validate the command in AIX 5.3 before executing the command?

Thanks,

script?
man ksh

script you can validate using -n switch for ksh:
-n
Reads commands and checks them for syntax errors, but does not
execute them. This flag is ignored for interactive shells.

For example,

When I enter "ls" in my ksh shell, then output is displayed. Whereas, if I enter "ls -4" (which is a wrong argument) an error message is displayed.

I dont want to display the default error message in my shell script, if the input command is wrong. Instead, I need to print my own error message.

Hmm,
what about
<snip>
command 1>/dev/null 2>&1
if $? != 0
then
echo "command has error: here stands my message"
else
echo "command looks ok"
fi
