[root@centos7 test]# ls
a.txt  b.txt  c.txt  d.txt  e.txt  f.txt

 

2、删除b.txt文件以外的所有文件

method1:

[root@centos7 test]# rm !("b.txt")
[root@centos7 test]# ls
b.txt

 

method2:

[root@centos7 test]# touch {a..f}.txt
[root@centos7 test]# ls
a.txt  b.txt  c.txt  d.txt  e.txt  f.txt
[root@centos7 test]# find ./ -not -name "b.txt" -exec rm -f {} \;
rm: cannot remove ‘./’: Is a directory
[root@centos7 test]# ls
b.txt

 

method3:

[root@centos7 test]# touch {a..f}.txt
[root@centos7 test]# ls
a.txt  b.txt  c.txt  d.txt  e.txt  f.txt
[root@centos7 test]# ls | grep -v "b.txt" | xargs rm -f
[root@centos7 test]# ls
b.txt

 

3、删除 b.txt和c.txt以外的文件

[root@centos7 test]# touch {a..f}.txt
[root@centos7 test]# ls
