Shell Programming and Scripting

I wrote a script in ksh as follow:

echo "Hello"

if [ $# -eq 0 ]; then
echo "bye"
else
echo "Welcome"
fi

i ran this script two time with different syntax like this:

~/my_temp [151]> ./test.ksh
Hello
bye

~/my_temp [152]> test.ksh
WIDTH: 12
WIDTH: 17
RELEASE [06.12.00.00]


Any idea why i am getting two different outputs and whats then meaning of second output.

You are inovking your script from the current working directory using ./
The other command could be picking up something from the path

I have run your script under bash and ksh and not got this unusual output.

I ran your script under ksh but when i executed test.ksh it just says,command not found.

what is your UNIX environment?

> vi test.ksh
"test.ksh" 9 lines, 72 characters

echo "Hello"

if [ $# -eq 0 ]; then
echo "bye"
else
echo "Welcome"
fi

~

~
"test.ksh" 9 lines, 86 characters
> ./test.ksh
Hello
bye
> test.ksh
test.ksh: Command not found.

My default shell is tcsh and i am running this script on HP-UX

Run the script in bash shell or and a magic element top of the script...as

Code:

#!/bin/bash

it will give the result
