\&\f(CW\*(C`rename\*(C'\fR
renames the filenames supplied according to the rule specified as the
first argument.
The \fIperlexpr\fR 
argument is a Perl expression which is expected to modify the \f(CW$_\fR
string in Perl for at least some of the filenames specified.
If a given filename is not modified by the expression, it will not be
renamed.
If no filenames are given on the command line, filenames will be read
via standard input.
.PP
For example, to rename all files matching \f(CW\*(C`*.bak\*(C'\fR to strip the extension,
you might say
.PP
.Vb 1
\&        rename \*(Aqs/\e.bak$//\*(Aq *.bak
.Ve
.PP
To translate uppercase names to lower, you'd use
.PP
.Vb 1
\&        rename \*(Aqy/A\-Z/a\-z/\*(Aq *
.Ve

so had to be used with care.
