1、查看内核
root@PC1:~/GS/lihua/test# hostnamectl Static hostname: PC1 Icon name: computer-vm Chassis: vm Machine ID: dc50d4dc469c45ea8a2a10f39caa45e9 Boot ID: 28566ddce150405d8573cdbbd676465d Virtualization: vmware Operating System: Ubuntu 20.04.3 LTS Kernel: Linux 5.11.0-38-generic Architecture: x86-64
2、问题, 在红帽、centos中不会出现这样的问题
root@PC1:~/GS/lihua/test# ls a.mp4 dup1.mp4 dup2.mp4 dup4.mp4 root@PC1:~/GS/lihua/test# rename mp4 txt * Bareword "mp4" not allowed while "strict subs" in use at (user-supplied code).
3、经查询找到的解决方法,类似sed的替换命令
root@PC1:~/GS/lihua/test# ls a.mp4 dup1.mp4 dup2.mp4 dup4.mp4 root@PC1:~/GS/lihua/test# rename 's/mp4/txt/' * root@PC1:~/GS/lihua/test# ls a.txt dup1.txt dup2.txt dup4.txt
