2.13 Batch Rename and move

The rename command modifies the file name with a Perl regular expression. Comprehensive use of Find, rename and mv.

1. The simplest way to rename an image file in the current directory with a specific format is to use the following script:

#!/bin/bash

#文件名: rename.sh

#用途: rename. jpg and. png files

Count=1;

For IMG in ' find. -iname ' *.png '-o-iname ' *.jpg '-type f-maxdepth 1 '

Do

new=image-$count. ${img##*.}

echo "Renaming $img to $new"

MV "$img" "$new"

Let count++

Done

Output Result:

$./rename.sh

Renaming back.jpg to Image-1.jpg

Renaming new.jpg to Image-2.jpg

Renaming Next.png to Image-3.jpg

The script renames all the. jpg and. png files in the current directory, the format of the new file name is Image-1.jpg, Image-2.jpg, and so on.

2. Working principle

Using the Find command to search,-O is used to specify multiple-iname options, which are used to perform case-insensitive matching. -maxdepth 1 refers to matching in the current directory.

To track the image number, initialize the Count=1, and the next step is to rename the file with the MV command. Therefore, a new file name needs to be constructed. ${img##*.} Resolves the file name that is in the current loop and obtains the filename extension.

Let count++ is used to increment the file number in each loop,

There are many other ways to perform a rename operation,

$ rename *. JPG *.jpg

Replace spaces in filenames with characters "_"

$ Rename ' s//_/g ' *

' s//_/g ' is used to replace a file name, and * is a wildcard used to match the target file, which can appear in *.txt or other styles

Convert file name to case

$rename ' y/a-z/a-z/' *

Move all. mp3 files into the given directory

$find path-type f-name "*.mp3"-exec mv {} target_dir \;

Replace spaces in all filenames with characters "_"

$find path-type f-exec Rename ' s//_/g ' {} \;
