Linux文件内容查看

文件内容查看

Linux系统中使用一下命令来查看文件的内容

网络配置目录：cd/ect/sysconfig/network-scripts

 1 [root@iZ2zeg6rjsjbfv9ibttfdnZ sysconfig]# cd /etc/sysconfig/network-scrip/
 2 [root@iZ2zeg6rjsjbfv9ibttfdnZ network-scripts]# ls
 3 ifcfg-eth0   ifdown-ppp       ifup-eth     ifup-sit
 4 ifcfg-lo     ifdown-routes    ifup-ippp    ifup-Team
 5 ifdown       ifdown-sit       ifup-ipv6    ifup-TeamPort
 6 ifdown-bnep  ifdown-Team      ifup-isdn    ifup-tunnel
 7 ifdown-eth   ifdown-TeamPort  ifup-plip    ifup-wireless
 8 ifdown-ippp  ifdown-tunnel    ifup-plusb   init.ipv6-global
 9 ifdown-ipv6  ifup             ifup-post    network-functions
10 ifdown-isdn  ifup-aliases     ifup-ppp     network-functions-ipv6
11 ifdown-post  ifup-bnep        ifup-routes

 

cat由第一行开始显示文件内容，用来读文章，或者配置文件，又使用cat

 1 [root@iZ2zeg6rjsjbfv9ibttfdnZ network-scripts]# cat ifcfg-eth0 
 2 # Created by cloud-init on instance boot automatically, do not edit.
 3 # If you don't want cloud-init genrated automatically,you can disable it in /etc/cloud/cloud.cfg
 4 # For more information, please refer to: https://help.aliyun.com/document_detail/57803.html
 5 #
 6 BOOTPROTO=dhcp
 7 DEVICE=eth0
 8 ONBOOT=yes
 9 STARTMODE=auto
10 TYPE=Ethernet
11 USERCTL=no

 

tac从最后一行开始显示，可以看出tac是cat的倒写

 1 [root@iZ2zeg6rjsjbfv9ibttfdnZ network-scripts]# tac ifcfg-eth0 
 2 USERCTL=no
 3 TYPE=Ethernet
 4 STARTMODE=auto
 5 ONBOOT=yes
 6 DEVICE=eth0
 7 BOOTPROTO=dhcp
 8 #
 9 # For more information, please refer to: https://help.aliyun.com/document_detail/57803.html
10 # If you don't want cloud-init genrated automatically,you can disable it in /etc/cloud/cloud.cfg
11 # Created by cloud-init on instance boot automatically, do not edit.

 

nl显示的时候，顺道输出行号（常用）

 1 [root@iZ2zeg6rjsjbfv9ibttfdnZ network-scripts]# nl ifcfg-eth0 
 2      1    # Created by cloud-init on instance boot automatically, do not edit.
 3      2    # If you don't want cloud-init genrated automatically,you can disable it in /etc/cloud/cloud.cfg
 4      3    # For more information, please refer to: https://help.aliyun.com/document_detail/57803.html
 5      4    #
 6      5    BOOTPROTO=dhcp
 7      6    DEVICE=eth0
 8      7    ONBOOT=yes
 9      8    STARTMODE=auto
10      9    TYPE=Ethernet
11     10    USERCTL=no

 

more一页一页的显示文件内容，带余下内容（空格代表翻页，enter代表向下看一行，：f行号）
