A whole .deb for such a simple problem seems overkill. The
file/manpage below is what I use. It was in the Perl4 distribution.
Presumably perl5 comes with it too in the source. I have it as
/usr/local/bin/rename.

.SH NAME
rename \- renames multiple files
.SH SYNOPSIS
.B rename [-i] perlexpr [files]
.SH DESCRIPTION
.I Rename
renames the filenames supplied according to the rule specified as the
first argument.
The argument is a Perl expression which is expected to modify the $_
string in Perl for at least some of the filenames specified.
If a given filename is not modified by the expression, it will not be
renamed.
If no filenames are given on the command line, filenames will be read
via standard input.
.PP
The
.B \-i
flag will prompt to remove the old file first if it exists. This
flag will be ignored if there is no tty.
.PP
For example, to rename all files matching *.bak to strip the extension,
you might say
.nf
rename 's/\e.bak$//' *.bak
.fi
To translate uppercase names to lower, you'd use
.nf
rename 'y/A-Z/a-z/' *
.fi
To do the same thing but leave Makefiles unharmed:
.nf
rename 'y/A-Z/a-z/ unless /^Make/' *
.fi
To rename all the *.f files to *.BAD, you'd use
.nf
rename 's/\e.f$/.BAD/' *.f
.SH ENVIRONMENT
.fi
No environment variables are used.

.SH DIAGNOSTICS
If you give an invalid Perl expression, you'll get a syntax error.
.SH BUGS
.I Rename
does not check for the existence of target filenames (without
the -i switch), so use with care.
