file

File Read

Each input line is treated as a filename for the `file` command and the output is corrupted by a suffix `:` followed by the result or the error of the operation.

file -f /path/to/input-file

Each line is corrupted by a prefix string and wrapped inside quotes. If a line in the target file begins with a `#`, it will not be printed as these lines are parsed as comments. It can also be provided with a directory and will read each file in the directory.

file -m /path/to/input-file
