Shell/Bash 或 Perl 中是否有可以重命名文件夹中所有文件的命令。
在1 中，计数器保持不变，但我也想更改计数器。
我要在我的文件夹中查找具有以下命名约定的文档：
smith_welding_<XXXXXX>.jpg
其中XXXXXX是计数器，从001191开始到001254.jpg
我想用上面给定的约定重命名所有文件，计数器需要从000000开始：
smith_welding_<XXXXXX>.jpg
是否有任何命令可以帮助我完成上述操作？
【问题讨论】：
有 Perl rename 应用程序。它通常在包rename (Debian) 或perl-rename 或类似的东西中。
$ cat `which /usr/bin/rename`
#!/usr/bin/perl -w
eval 'exec /usr/bin/perl -w -S $0 ${1+"$@"}'
if 0; # not running under some shell

=head1 NAME
rename - renames multiple files
=head1 SYNOPSIS
B<rename>
S<[ B<-h>|B<-m>|B<-V> ]>
S<[ B<-v> ]>
S<[ B<-n> ]>
S<[ B<-f> ]>
S<[ B<-e>|B<-E> I<perlexpr>]*|I<perlexpr>>
S<[ I<files> ]>
=head1 DESCRIPTION
C<rename>
renames the filenames supplied according to the rule specified as the
first argument.
The I<perlexpr>
argument is a Perl expression which is expected to modify the C<$_>
string in Perl for at least some of the filenames specified.
If a given filename is not modified by the expression, it will not be
renamed.
If no filenames are given on the command line, filenames will be read
via standard input.
For example, to rename all files matching C<*.bak> to strip the extension,
you might say
rename 's/\e.bak$//' *.bak
To translate uppercase names to lower, you'd use
rename 'y/A-Z/a-z/' *
=head1 OPTIONS
=over 8
=item B<-v>, B<-verbose>
Verbose: print names of files successfully renamed.
=item B<-n>, B<-nono>
No action: print names of files to be renamed, but don't rename.
=item B<-f>, B<-force>
Over write: allow existing files to be over-written.
=item B<-h>, B<-help>
Help: print SYNOPSIS and OPTIONS.
=item B<-m>, B<-man>
Manual: print manual page.
=item B<-V>, B<-version>
Version: show version number.
=item B<-e>
Expression: code to act on files name.
May be repeated to build up code (like C<perl -e>).
If no B<-e>, the first argument is used as code.
=item B<-E>
Statement: code to act on files name, as B<-e> but terminated by ';'.
=back
=head1 ENVIRONMENT
No environment variables are used.

=head1 DIAGNOSTICS
If you give an invalid Perl expression you'll get a syntax error.
=head1 BUGS
The original
C<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).
=cut
这样就可以解决问题了：
rename 'our$i;$_=sprintf"smith_welding_%06d.jpg",++$i' *.jpg
【讨论】：
你可以轻松做到：
i=0; for image in *.jpg; do mv "$image" "smith_welding_`printf "%.5d"`$i.jpg"; ((i++)); done
输出：
smith_welding_000000.jpg
smith_welding_000001.jpg
smith_welding_000002.jpg
