Linux命令之rename

一、引言

今天才知道Linux下的rename有两个版本，util-linux工具集的rename和Perl版本的rename，而两者的用法是明显不一样的，Perl版rename相对比较强大

二、对比

RENAME()                                                         Perl Programmers Reference Guide                                                        RENAME()

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.

DIAGNOSTICS

       If you give an invalid Perl expression you'll get a syntax error.

BUGS

       The original "rename" did not check for the existence of target filenames, so had to be used with care.  I hope I've fixed that (Robin Barker).

perl v5.18.2                                                                 --                                                                   RENAME()

可以看到它的使用方法是 rename [ -v ] [ -n ] [ -f ] perlexpr [ files ] 支持perl正则表达式的，这就是它强大的原因

RENAME()                  Linux Programmer’s Manual                 RENAME()

NNAAMMEE

       rename - Rename files

SYNOPSIS

       rename from to file...

       rename -V

DESCRIPTION

       rename  will  rename  the specified files by replacing the first occurrence of from in their name by to.

       -V, --version

              Display version information and exit.

       For example, given the files

              foo1, ..., foo9, foo10, ..., foo278, the commands

              rename foo foo0 foo?

              rename foo foo0 foo??

       will turn them into foo001, ..., foo009, foo010, ..., foo278.

       And

              rename .htm .html *.htm

       will fix the extension of your html files.

       mmv(), mv()

AVAILABILITY

       The rename command is part of the util-linux-ng package and  is  avail-

       able from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
