How to Remove Files in Linux

 To remove (or delete) a file or directory in Linux from the command line, use the rm(remove) command.

Be extra careful when removing files or directories with the rm command, because once the file is deleted it cannot be recovered.

• To delete a single file use, the rm command followed by the file name:

rm filename

Copy

If the file is write protected you will be prompted for confirmation as shown below. To remove the file type y and hit Enter. Otherwise, if the file is not write protected it will be deleted without prompting.

rm: remove write-protected regular empty file 'filename'?

Copy

• To delete multiple files at once use the rm command followed by the file names separated by space.

rm filename1 filename2 filename3

Copy

You can also use a wildcard (*) and regular expansions to match multiple files. For example to remove all .pdf files in the current directory, use the following command:

rm *.pdf

Copy

When you use rm with wildcards (*) and regular expansions, it is recommended to list the files with the ls command so that you can see what files will be deleted before running the rm command.

• Use the -i option to confirm each file before deleting it:

rm -i filename(s)

Copy

• To remove files without prompting even if the files are write-protected use the -f(force) option:

rm -f filename(s)

Copy

• You can also combine rm options. For example, to remove all .txt files in the current directory without a prompt in verbose mode, use the following command:

rm -fv *.txt

Copy

How to Remove Directories (Folders)

• To remove an empty directory use the -d option.

rm -d dirname

Copy

• To remove non-empty directories and all the files within them, use the r (recursive) option.

rm -r dirname

Copy

If a directory or a file within the directory is write-protected, you will be prompted to confirm the deletion.

• To remove non-empty directories and all the files without being prompted use the r(recursive) and -f options.

rm -rf dirname

Copy

• To remove multiple directories at once, use the rm command followed by the directory names separated by space.

rm -r dirname1 dirname2 dirname3

Copy

Same as with files you can also use a wildcard (*) and regular expansions to match multiple directories
