Special Forums UNIX Desktop Questions & Answers Rename files without using for loop Post 302378092 by Qwerty123 on Monday 7th of December 2009 12:57:59 AM

Yes, 'Rename' command works. But I have to rename all the files that are present in the directory at a time without using a 'For' loop.

Is that possible? Is there any command or idea for doing this?

Thanks.

NAME
rename - rename files SYNOPSIS
rename [options] expression replacement file... DESCRIPTION
rename will rename the specified files by replacing the first occurrence of expression in their name by replacement. OPTIONS
-v, --verbose Give visual feedback which files where renamed, if any. -V, --version Display version information and exit. -s, --symlink Peform rename on symlink target -h, --help Display help text and exit. EXAMPLES
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. WARNING
The renaming has no safeguards. If the user has permission to rewrite file names, the command will perform the action without any ques- tions. For example, the result can be quite drastic when the command is run as root in the /lib directory. Always make a backup before running the command, unless you truly know what you are doing. SEE ALSO
mmv(1), mv(1) AVAILABILITY
The rename command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux June 2011 RENAME(1)
