# files older than two weeks in the temp folder are found and then piped to the xargs command which runs the rm command on each file and removes them
$ find /tmp -mtime +14 | xargs rm
# The find command supports the -exec option that allows arbitrary commands to be performed on found files. The following are equivalent.
$ find ./foo -type f -name "*.txt" -exec rm {} \;
$ find ./foo -type f -name "*.txt" | xargs rm
# The -t option prints each command that will be executed to the terminal. This can be helpful when debugging scripts.
$ echo 'one two three' | xargs -t rm
rm one two three
