    rm filename
  

• Remove multiple files

    rm file1 file2 file3
  

Common Options

• Interactive mode (prompt before every removal)

    rm -i filename
  

• Force removal (ignore nonexistent files and never prompt)

    rm -f filename
  

• Recursive removal (remove directories and their contents)

    rm -r directoryname
  

• Verbose mode (explain what is being done)

    rm -v filename
  

• Remove directories (same as -r)

    rm -d directoryname
  

Examples

• Remove a single file

    rm file.txt
  

• Remove multiple files

Practical Tips

• Safety First: Use the -i option to prevent accidental deletions.

• Force Removal: Use the -f option to force the removal of files without prompts, but use it cautiously.
