Over view about Shell Scripting Homework Help:
What is shell scripting? To put it in layman terms a computer understands only 0s and 1s. For a normal human being it is very difficult to program or read instructions consisting of only 0s and 1s. To overcome this difficultly there is something called a shell which accepts commands or instructions in English, validates the command and passes it to the kernel for execution.
A shell essentially is a user program. A shell script is a command line interpreter, it takes input from standard input devices like keyboards or files and executes the commands.
Advantages of Shell Scripting:
- Less time taken to write a shell script as compared to equivalent code in other
- Interactive debugging of a shell script is possible
- Ease of file or program selection
- Shell script Loads and executes quickly
- Since a shell script is executed by a interpreter, it is easier to embed a debugging code into a script to detect and fix bugs
Dis-advantages of Shell Scripting:
- Shell script has a slow execution speed as it is a interpretive language
- Another reason for slow execution is the need to launch a new process for almost
every command executed
- If we compare a normal compiled programs execution time to the execution time of
a equivalent shell script then the shell script is several magnitudes slower
- Compatibility issues between different platforms
Different Shells that are available:
- BASH (Bourne Again Shell)
- CSH (C Shell)
- KSH (Korn Shell)
