The line #!/usr/bin/bash is known as a "shebang" or "hashbang." It indicates the interpreter that should be used to execute the script that follows. Here's a breakdown:
#!: This sequence tells the system that the file is a script and specifies the interpreter to use./usr/bin/bash: This is the path to the Bash shell interpreter. It tells the system to use the Bash shell located at that path to run the script.
When you run a script that starts with this line, the operating system uses the specified interpreter to execute the commands in the script. If the path is incorrect or the interpreter is not available, the script will not run.
