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/' *

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).
