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. |
