I have problem to run script.
I can run script with command
but if i run script as
, it doesn't run. the permission for the script is: -rwxr-xr-x.
my server is SunOS 5.10 Generic_150400-48 sun4v sparc sun4v
do we need to setup something to run command as ./script_name.ksh?
when you say that it doesn't run, what does it mean? Any error messages? Anything get output?
Please post the first 10 lines of the script using code tags.

thanks vgersh99 for you responding.
when running script with ./script_name.ksh, it doesn't give anything.
initial script like below
.
I changed to below, it works fine. could you please let me know why I can not use . ${HOME}/.profile in the script?
you had a leading space in the first line: #!/bin/ksh
The first line containing the path to shell interpreter to be used for the script should start with #! followed by a path to a shell interpreter.
Unless it's a copy/paste error when you posted.

That depends - among other things - on what is in ~/.profile. One conceivable cause could be: $# is the number of (commandline) parameters the current process got. i.e. Consider this script:
The following table shows what it would produce if called in the respective way:
etc.
You called your script without any parameter (as far as i can see) and so the test if (( $# < 1 )) should be true and the then-branch be executed. But inside your ~/profile script you could have a line:
and because you dot-execute the script this makes changes to your current environment, by setting "$1" (the first positional argument) to "X" (notice that instead of "x" any other value would also be possible) - which in turn makes "$#" return 1, not 0 any more.
change your script the following way for debugging:

I hope this helps.

thanks bakunin and vgersh99. it is working now. I deleted the line . ${HOME}/.profile and re-type it. it works. before deleting, use cat -evt to check, there is no hiden characters. Not sure why.
thanks again for your valuable suggestion.
