awesome, it was successful . i understand that chmod u+x is to make the ss1.sh executable. but what does PATH=.:$PATH do ?

See? That's why I didn't want to tell you!

Your current directory can be referenced as . (dot)

That's why ./SS1 refers to SS1 in your current directory.

To avoid using ./SS1 and use just SS1, you need to add your current directory (.) to your path. PATH=.:$PATH adds . (your current directory) to your path.

It is highly recommended that you don't put (.) in your PATH for security reasons. Either call the script with the path, or put the script in a directory that is already on your path, or add a specific directory to your path and put the script there.

Hi Irishboy, provide an 'execute' permission to the file..
chmod 766 <filename>
This will give -rwxrw-rw- permission to the file. Now try running your script.

I would recommend 744 or 755 instead of 766. There's probably no reason to make the file writable by everyone on the system.

Consider the Unix command sequence ps aux | grep -iv apache2 | wc -l This command will output the total number of apache2 processes running.
