rename 's/.txt$/.doc/' *
NAME
rename - renames multiple files
SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first
argument. The perlexpr argument is a Perl expression which is expected to modify the
$_ string in Perl for at least some of the filenames specified. If a given filename
is not modified by the expression, it will not be renamed. If no filenames are given
on the command line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the extension, you might
say
rename 's/\.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
OPTIONS
-v, --verbose
Verbose: print names of files successfully renamed.
-n, --no-act
No Action: show what files would have been renamed.
-f, --force
Force: overwrite existing files.
ENVIRONMENT
No environment variables are used.
