| 30 | .TH RENAME 1 "July 30, 1990" |
| 31 | .AT 3 |
| 32 | .SH NAME |
| 33 | rename \- renames multiple files |
| 34 | .SH SYNOPSIS |
| 35 | .B rename perlexpr [files] |
| 36 | .SH DESCRIPTION |
| 37 | .I Rename |
| 38 | renames the filenames supplied according to the rule specified as the |
| 39 | first argument. |
| 40 | The argument is a Perl expression which is expected to modify the $_ |
| 41 | string in Perl for at least some of the filenames specified. |
| 42 | If a given filename is not modified by the expression, it will not be |
| 43 | renamed. |
| 44 | If no filenames are given on the command line, filenames will be read |
| 45 | via standard input. |
| 46 | .PP |
| 47 | For example, to rename all files matching *.bak to strip the extension, |
| 48 | you might say |
| 49 | .nf |
| 50 | |
| 51 | rename 's/\e.bak$//' *.bak |
| 52 | |
| 53 | .fi |
| 54 | To translate uppercase names to lower, you'd use |
| 55 | .nf |
| 56 | |
| 57 | rename 'y/A-Z/a-z/' * |
| 58 | |
| 59 | .fi |
| 60 | .SH ENVIRONMENT |
| 61 | No environment variables are used. |

| 71 | .SH BUGS |
| 72 | .I Rename |
| 73 | does not check for the existence of target filenames, so use with care. |
