In bash scripting, an operator is a special symbol or keyword used to perform specific operations on data or variables. these operators enable you to manipulate and control data within your bash scripts. Use bash to manage it infrastructure. in this module, you will: learn what shells are and what bash is. learn about the syntax of bash commands. learn how to use i o operators to redirect input and output. learn how to update a server's operating system. learn how to find and terminate rogue processes. Conditional expressions are used by the [[ compound command (see conditional constructs) and the test and [ builtin commands (see bourne shell builtins). the test and [ commands determine their behavior based on the number of arguments; see the descriptions of those commands for any other command specific actions.
