# rename-5.004(1p)

renames multiple files

## NAME

rename - renames multiple files

## SYNOPSIS

**rename** \[ **-v** \] *perlexpr* \[ *files* \]

## DESCRIPTION

`rename` renames the filenames supplied according to the rule specified as the first argument. The *perlexpr*  argument is a Perl expression which is expected to modify the `$_` string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input.

For example, to rename all files matching `*.bak` to strip the extension, you might say

```
        rename 's/\e.bak$//' *.bak
```

To translate uppercase names to lower, you'd use

```
        rename 'y/A-Z/a-z/' *
```

## OPTIONS

- **-v**

  Verbose: print names of files successfully renamed.

## ENVIRONMENT

No environment variables are used.

## SEE ALSO

[*mv*(1)](/mv/1.md), [*perl*(1)](/perl/1.md)

## DIAGNOSTICS

If you give an invalid Perl expression you'll get a syntax error.

## BUGS

The original `rename` did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin Barker).
