Description:
The File Operations Script is a Bash script designed to verify the existence of a specified file and, if present, to display its content.
Functionality:
File Existence Check: The script begins by checking the existence of a specified file within the system.
Content Display: If the file exists, the script proceeds to display its content to the terminal using the cat command.
Feedback: Depending on the file's existence, the script provides appropriate feedback to the user:
If the file exists, it confirms the presence of the file and shows its content.
If the file does not exist, it notifies the user about its absence.
Usage:
Users can modify the file="sample_text.txt" line within the script to specify the file they wish to check.
Execution of the script (chmod +x filename.sh) and then (./filename.sh) in a terminal environment triggers the file check and content display process.
Purpose:
The primary purpose of this script is to streamline the process of checking for the existence of a file and displaying its content if available. It aids users in swiftly validating file presence and accessing their contents within a Bash script environment.
