1、rename命令
[root@centos79 test]# ls a.mp4 dup1.mp4 dup2.mp4 dup4.mp4 [root@centos79 test]# rename mp4 txt *.mp4 [root@centos79 test]# ls a.txt dup1.txt dup2.txt dup4.txt
2、利用循环语句
[root@centos79 test]# ls a.txt dup1.txt dup2.txt dup4.txt [root@centos79 test]# n=1; for file in *.txt; do num=$(printf "%02d" $n); mv $file new$num.mp3; let n=n+1;done [root@centos79 test]# ls new01.mp3 new02.mp3 new03.mp3 new04.mp3
3、实现按照文件大小递增命名
[root@centos79 test]# ls a.txt b.txt c.txt d.txt [root@centos79 test]# ll -h total 170M -rw-r--r--. 1 root root 50M Jul 6 19:21 a.txt -rw-r--r--. 1 root root 10M Jul 6 19:21 b.txt -rw-r--r--. 1 root root 80M Jul 6 19:21 c.txt -rw-r--r--. 1 root root 30M Jul 6 19:21 d.txt [root@centos79 test]# a=$(ls -S | xargs du -sh | tac | cut -f 2) [root@centos79 test]# echo $a b.txt d.txt a.txt c.txt [root@centos79 test]# n=1; for file in $a; do num=$(printf "%02d" $n); mv $file $num.txt; let n=n+1; done [root@centos79 test]# ls 01.txt 02.txt 03.txt 04.txt [root@centos79 test]# ll -h total 170M -rw-r--r--. 1 root root 10M Jul 6 19:21 01.txt -rw-r--r--. 1 root root 30M Jul 6 19:21 02.txt -rw-r--r--. 1 root root 50M Jul 6 19:21 03.txt -rw-r--r--. 1 root root 80M Jul 6 19:21 04.txt
