Linux or UNIX - Find and remove file syntax

The basic find command syntax is:

find dir-name criteria action

  1. dir-name : - Defines the working directory such as look into /tmp/
  2. criteria : Use to select files such as "*.sh"
  3. action : The find action (what-to-do on file) such as delete the file.

To remove multiple files such as *.jpg or *.sh with one command find, use:

find . -name "FILE-TO-FIND" -exec rm -rf {} \;

OR

find . -type f -name "FILE-TO-FIND" -exec rm -f {} \;

The only difference between above two syntax is that the first command remove directories as well where second command only removes files. Options:

  1. -name "FILE-TO-FIND" : File pattern.
  2. -exec rm -rf {} \; : Delete all files matched by file pattern.
  3. -type f : Only match files and do not include directory names.

Examples of find command

WARNING! These examples may crash your computer if executed. Before removing file makes sure, you have backup of all-important files. Do not use rm command as root user it can do critical damage to the system.

Find all files having .bak (*.bak) extension in the current directory and remove them:
$ find . -type f -name "*.bak" -exec rm -f {} \;

Find all core files in the / (root) directory and remove them (be careful with this command):
# find / -name core -exec rm -f {} \;

Find all *.bak files in the current directory and removes them with confirmation from user:
$ find . -type f -name "*.bak" -exec rm -i {} \;
Sample outputs:

rm: remove regular empty file `./data0002.bak'? y
rm: remove regular empty file `./d234234234fsdf.bak'? y
rm: remove regular empty file `
