What are the steps required to make a script executable on Unix?..

Answer / chaitanya

The steps that are required to make a script executable are to:

• First create a script file and write the code that has to be executed in it.

• Make the file mode as executable by making the first line starts with #! this is the line that python interpreter reads.

• Set the permission for the file by using chmod +x file. The file uses the line that is the most important line to be used:

#!/usr/local/bin/python

• This explains the pathname that is given to the python interpreter and it is independent of the environment programs.

• Absolute pathname should be included so that the interpreter can interpret and execute the code accordingly. The sample code that is written:

#! /bin/sh

# Write your code here

exec python $0 ${1+"$@"}

# Write the function that need to be included.
