File Descriptions

Top-Level Files

• README.md: This file, providing an overview of the project.

FilesAndDirectories

• 1_flagPackege.go: Demonstrates the use of the flag package for parsing command-line arguments.
• 2_simbLink.go: Checks if a file is a symbolic link and resolves its real path.
• 3_pwd.go: Implements the pwd command to print the current working directory.
• 4_which.go: Implements the which command to locate a command in the system's PATH.
• 5_PermissionBitsOfFile.go: Displays the permission bits of a specified file.
• 6_traversing_diretoryTree.go: Traverses a directory tree and prints all paths.
• 7_visitingOnlyDirectories.go: Visits and prints only directories in a directory tree.
• 8_findv1.go: A basic implementation of the find command to locate files and directories.

FilesAndDirectories/FileOperation

• deleteFile.go: Deletes a specified file.
• dummy.json: A sample JSON file for testing purposes.
• renameFile.go: Renames a file, with support for overwriting.
