ls命令用来显示目标列表,在Linux中是使用率较高的命令。ls命令的输出信息可以进行彩色加亮显示,以分区不同类型的文件。实例
显示当前目录下非影藏文件与目录
[[email protected] ~]# ls
anaconda-ks.cfg install.log install.log.syslog satools
显示当前目录下包括影藏文件在内的所有文件列表
[[email protected] ~]# ls -a
. anaconda-ks.cfg .bash_logout .bashrc install.log .mysql_history satools .tcshrc .vimrc
.. .bash_history .bash_profile .cshrc install.log.syslog .rnd .ssh .viminfo
输出长格式列表
[[email protected] ~]# ls -1
anaconda-ks.cfg
install.log
install.log.syslog
satools
显示文件的inode信息
索引节点(index inode简称为“inode”)是Linux中一个特殊的概念,具有相同的索引节点号的两个文本本质上是同一个文件(除文件名不同外)。
[[email protected] ~]# ls -i -l anaconda-ks.cfg install.log
2345481 -rw------- 1 root root 859 Jun 11 22:49 anaconda-ks.cfg
2345474 -rw-r--r-- 1 root root 13837 Jun 11 22:49 install.log
水平输出文件列表
[[email protected] /]# ls -m
bin, boot, data, dev, etc, home, lib, lost+found, media, misc, mnt, opt, proc, root, sbin, selinux, srv, sys, tmp, usr, var

[[email protected] ~]# ls -R
.:
anaconda-ks.cfg install.log install.log.syslog satools
