- Pipes and redirection: This is a powerful technique that allows you to take the output from one command and use it as the input to another command. The vertical bar (|) is used to pipe the output of one command to another, while redirection (>, >>, <) is used to redirect the input or output of a command to a file.
- Command substitution: This technique allows you to substitute the output of a command into a variable or a command line argument. The syntax for command substitution is $(command) or
command. - Conditional statements: Bash supports if-else statements that allow you to execute different commands based on a condition.
- oops: Bash supports for, while and until loops that allow you to execute a set of commands repeatedly.
- Functions: Bash supports the creation of functions, which are reusable blocks of code.
- These are just a few of the many bash coding techniques that can be used to make your scripts more efficient and powerful.
