The most straightforward way to rename a file in UNIX/Linux is using the mv command. Simply type mv old_filename new_filename to rename your file.
For renaming files in different directories, use absolute paths. Example: mv /home/user/oldfile.txt /home/user/newfile.txt to rename along with changing the file's location.
Need to rename multiple files? The mv command can be used in loops or bash scripts to rename files in bulk.
The rename command is excellent for renaming multiple files. To change all .txt files to .md, use: rename 's/.txt/.md/' *.txt.
To rename files spread across multiple directories, combine the find command with mv or rename for more complex file renaming tasks.
