If I am a junior UNIX/Linux system administrator, and I want to make automation tasks for the server.
I know Shell script, Perl, and Python. All of these are used to make automation tasks.
Which one I can use to make the scripts?
Answer should be according to these conditions: 1. less lines of code. 2. high performance. 3. Portable source code, even I use KSH or BASH shell.
If there is no dedicated answer, so when I can use perl and when python and when shell-script?
