75 =head1 NAME | |
76 | |
77 rename - renames multiple files | |
78 | |
79 =head1 SYNOPSIS | |
80 | |
81 B<rename> S<[ B<-v> ]> S<[ B<-n> ]> S<[ B<-f> ]> I<perlexpr> S<[ I<files> ]> | |
82 | |
83 =head1 DESCRIPTION | |
84 | |
85 C<rename> | |
86 renames the filenames supplied according to the rule specified as the | |
87 first argument. | |
88 The I<perlexpr> | |
89 argument is a Perl expression which is expected to modify the C<$_> | |
90 string in Perl for at least some of the filenames specified. | |
91 If a given filename is not modified by the expression, it will not be | |
92 renamed. | |
93 If no filenames are given on the command line, filenames will be read | |
94 via standard input. | |
95 | |
96 For example, to rename all files matching C<*.bak> to strip the extension, | |
97 you might say | |
98 | |
99 rename 's/\.bak$//' *.bak | |
100 | |
101 To translate uppercase names to lower, you'd use | |
102 | |
103 rename 'y/A-Z/a-z/' * | |

107 =over 8 | |
108 | |
109 =item B<-v>, B<--verbose> | |
110 | |
111 Verbose: print names of files successfully renamed. | |
112 | |
113 =item B<-n>, B<--no-act> | |
114 | |
115 No Action: show what files would have been renamed. | |
116 | |
117 =item B<-f>, B<--force> | |
118 | |
119 Force: overwrite existing files. | |

135 =head1 DIAGNOSTICS | |
136 | |
137 If you give an invalid Perl expression you'll get a syntax error. | |
138 | |
139 =head1 BUGS | |
140 | |
141 The original C<rename> did not check for the existence of target filenames, | |
142 so had to be used with care. I hope I've fixed that (Robin Barker). | |
