Shell scripting
In the command line, a shell script is an executable file that contains a set of instructions that the shell will execute. Its main purpose its to reduce a set of instructions (or commands) in just one file. Also it can handle some logic because it's a programming language.
How to create it
- Create the file:
$ touch myscript.sh
- Add a shebang at the start of the file. The Shebang line is responsible for letting the command interpreter know which interpreter the shell script will be run with:
$ echo "#!/bin/bash" > myscript.sh
# or
$ your-desired-editor myscript.sh
# write at the first line #!/bin/bash
- Add some comands:
$ echo "echo Hello World!" >> myscript.sh
- Give the file execution mode:
$ chmod +x myscript.sh
- Execute it!
$ ./myscript.sh
Hello World!
