- Concatenate several files into the target file:

`cat {{file1}} {{file2}} > {{target_file}}`

- Append several files into the target file:

`cat {{file1}} {{file2}} >> {{target_file}}`

- Number all output lines:

`cat -n {{file}}`

- Display non-printable and whitespace characters (with `M-` prefix if non-ASCII):

`cat -v -t -e {{file}}`
