Linux下查看文件属性有多种方法，且这些方法中偏向不同，具体如下：
1 ls
ls -a 查看所有文件
ls -l 查看详细的属性
[pc@li1209-91 ~]$ ls -a ; ls -l
. .. bak .bash_history .bash_logout .bash_profile .bashrc .lesshst .lftp lujiaz .ssh .viminfo wordpress wp-ueditor
total 16
drwxrwxr-x 3 pc pc 4096 Sep 10 12:37 bak
drwxr-xr-x 4 nginx root 4096 Jul 7 20:30 lujiaz
drwxr-xr-x 5 pc pc 4096 Sep 8 01:41 wordpress
drwxr-xr-x 3 root root 4096 Sep 11 11:57 wp-ueditor
2 lsattr
查看文件的扩展属性,
如果文件被 chattr +i 添加了写保护,
用lsattr可以看到添加的属性
[pc@li1209-91 ~]$ chattr +i test ; lsattr test
chattr: Operation not permitted while setting flags on test
-------------e- test
3 file
