说明

  more命令是将文件内容一页一页的显示，跟cat相比，cat命令是将文件内容一次性输出到屏幕。

格式

  more [option] [filename]

常用命令

• -num：指定屏幕显示大小为num行
• +num：从行号num开始显示
• -s：把连续的多个空行显示为一行
• -p：不滚屏，而是清楚整个屏幕，然后显示文本
• -c：不滚屏，而是从每一屏顶部开始显示文本，每显示完一行，就清楚这一行的剩余部分

交互命令

空格：下翻一屏
b：上翻一屏
/:搜索
=：输出当前行的行号
q：退出

示例

1、不使用任何参数

[root@localhost ~]# more /etc/services 
# /etc/services:
# $Id: services,v 1.55 2013/04/14 ovasik Exp $
#
# Network services, Internet style
# IANA services version: last updated 2013-04-10
#
# Note that it is presently the policy of IANA to assign a single well-known
# port number for both TCP and UDP; hence, most entries here have two entries
# even if the protocol doesn't support UDP operations.
.....

2、定义显示的行数，不会满屏显示内容，而只显示5行

[root@localhost ~]# more -5 /etc/services 
# /etc/services:
# $Id: services,v 1.55 2013/04/14 ovasik Exp $
#
# Network services, Internet style
# IANA services version: last updated 2013-04-10
--More--(0%)

3、从指定的行开始显示内容

[root@localhost ~]# more +999 /etc/services 
ibm-app         385/tcp                 # IBM Application
ibm-app         385/udp                 # IBM Application
asa             386/tcp                 # ASA Message Router Object Def.
asa             386/udp                 # ASA Message Router Object Def.
aurp            387/tcp                 # Appletalk Update-Based Routing Pro.
aurp            387/udp                 # Appletalk Update-Based Routing Pro.
unidata-ldm     388/tcp                 # Unidata LDM
unidata-ldm     388/udp                 # Unidata LDM
uis             390/tcp                 # UIS
...
ncld            405/tcp                 # ncld
ncld            405/udp                 # ncld
imsp            406/tcp                 # Interactive Mail Support Protocol
--More--(8%)

4、使用管道分页显示目录内容

[root@localhost ~]# ls /etc/|more -10
adjtime
aliases
aliases.db
alternatives
anacrontab
asound.conf
audisp
audit
avahi
bash_completion.d
--More--
