🤟motto:要敢于一个人默默的面对自己， ==强大自己才是核心==。不要等到什么都没有了，才下定决心去做。种一颗树，最好的时间是十年前，其次就是现在！学会自己和解，与过去和解，努力爱自己。==希望春天来之前，我们一起面朝大海，春暖花开！==🤟

前言
今天我们开始进行Linux知识的学习，这篇文章主要是承接上一篇文章【Linux常见指令大全（一）】继续书写Linux的基本指令！！！本系列的Linux的指令操作都是在云服务器上操作的。
——————————————————————————————
首先先写上几句话：献给坚持创作的我和点开这篇文章希望进步的你
1.无论你在寻找什么，亲情，友情，或爱情，终其一生，其实你都是一个人，极少有人能真正的像你一样理解你自己，哪怕是亲人，朋友或恋人，他们只能辅助你去理解自己，你唯一的人生课题就是找到自己。
2.不懂得爱自己的人，是没办法爱别人的。某些时候，怜悯不是爱，纵容不是爱，正确的爱是刚柔并济，褒贬具存的，是懒惰时的严厉，哭泣时的拥抱，懦弱时的鼓励，黑夜里的路灯。爱是让风筝飞行的风，是荒漠里久逢甘露，是戈壁滩种下的树，是暴风雨中飞翔的鸟，是你手中紧紧握住又愿意放出的风筝线，正确的爱不会让任何人痛苦，只会让你的精神和心灵在任何天气里都能走得更远站的更高。
3.有时候最大的伤害都来自于最亲近的人，但是你要记住你很好，而且做你自己就好，也不要怨恨，不要变成自己讨厌的样子，不要一直陷在怪圈里，对伤害最好的反击就是:让伤害到我为止。让伤害到我为止不是打碎牙往肚子里咽，而是我有能力消化离开，将我对美好未来的愿望积累，超过我对过去耿耿于怀的怨恨，不再执着责备，不愿耗费一分，可以忍着痛把它抹零，重新开始。理解过去的根源，消解过去的伤痛，和脱离这个怪圈。不计较是否解气是否公平是否委屈，有能忘却一切的决心和离开重新开始新的生活的勇气。
4.人生能真正有效改变自己的，只有为数不多的十来年，珍惜机遇，尤其是你还年轻的时候，比如读书。
5.每个人的生活都下了雪，尽量自己清扫自己的屋檐，体谅别人的辛苦，原谅偶尔的冷漠，没有人是永不疲惫的超人。但是如果可以，你要尽量力所能及做一个能温暖别人的人， 这种感觉也很好。
7.man指令（重要）：
Linux的命令有很多参数，我们不可能全记住，我们可以通过查看联机手册获取帮助。访问Linux手册页的命令是man
语法: man [选项] 命令
常用选项
-k 根据关键字搜索联机帮助
num 只在第num章节找
-a 将所有章节的都显示出来，比如 man printf 它缺省从第一章开始搜索，知道就停止，用a选项，当按 下q退出，他会继续往后面搜索，直到所有章节都搜索完毕。
解释一下,面手册分为8章
1 是普通的命令
2 是系统调用,如open,write之类的(通过这个，至少可以很方便的查到调用这个函数，需要加什么头文 件)
3 是库函数,如printf,fread
4是特殊文件,也就是/dev下的各种设备文件
5 是指文件的格式,比如passwd,
就会说明这个文件中各个字段的含义
6 是给游戏留的,由各个游戏自己定义
7 是附件还有一些变量,比如向environ这种全局变量在这里就有说明
8 是系统管理用的命令,这些命令只能由root使用,如ifconfig
1.man是一个查看命令，系统调用，C接口的一个手册！
2.手册是有编号的。
3.man默认是从1号手册开始查找，找到即停。
4.man可以根据指定手册查找man1/2/3------命令/接口/C
上面是Linux系统对man指令的解释【man man】
8.cp指令（重要）：
语法：cp [选项] 源文件或目录 目标文件或目录
功能: 复制文件或目录
说明:
cp指令用于复制文件或目录，如同时指定两个以上的文件或目录，且最后的目的地是一个已经存在的目录，
则它会把前面指定的所有文件或目录复制到此目录中。若同时指定多个文件或目录，而最后的目的地并非一个已存
在的目录，则会出现错误信息
常用选项：
-f 或 --force 强行复制文件或目录， 不论目的文件或目录是否已经存在
-i 或 --interactive 覆盖文件之前先询问用户
-r递归处理，将指定目录下的文件与子目录一并处理。若源文件或目录的形态，不属于目录或符号链 接，则一律视为普通文件处理8处理
cp 拷贝目录和文件，-r -f -i，同rm中的用法。

[root@VM-4-9-centos KongQing]# mkdir a/b/c
mkdir: cannot create directory ‘a/b/c’: No such file or directory
[root@VM-4-9-centos KongQing]# tree .

9.mv指令（重要）：
mv命令是move的缩写，可以用来移动文件或者将文件改名（move (rename) files），是Linux系统下常用的命
令，经常用来备份文件或者目录。
语法: mv [选项] 源文件或目录 目标文件或目录
功能:
- 视mv命令中第二个参数类型的不同（是目标文件还是目标目录），mv命令将文件重命名或将其移至一个新的
目录中。
- 当第二个参数类型是文件时，mv命令完成文件重命名，此时，源文件只能有一个（也可以是源目录名），它
将所给的源文件或目录重命名为给定的目标文件名。
- 当第二个参数是已存在的目录名称时，源文件或目录参数可以有多个，mv命令将各参数指定的源文件均移至
目标目录中。
1.类似剪切功能，move，移动文件或者目录
2.对文件或者目录进行重命名
常用选项：
-f ：force 强制的意思，如果目标文件已经存在，不会询问而直接覆盖
-i ：若目标文件 (destination) 已经存在时，就会询问是否覆盖
举例：
将rm改造成mv
vim ~/.bashrc #修改这个文件
mkdir -p ~/.trash
alias rm=trash
alias ur=undelfile
undelfile() {
mv -i ~/.trash/\$@ ./
}
trash() {
mv $@ ~/.trash/
}[root@VM-4-9-centos KongQing]# tree .

[root@VM-4-9-centos KongQing]# touch test
[root@VM-4-9-centos KongQing]# mkdir a/b/c

.

`-- test
4 directories, 1 file
[root@VM-4-9-centos KongQing]#
10.cat
语法：cat 选项
功能： 查看目标文件的内容
常用选项：
-b 对非空输出行编号
-n 对输出的所有行编号
-s 不输出多行空行
举例：
# cnt=0; while [ $cnt -le 1000 ] ; do echo "hello 106 [$cnt]"; let cnt++; done > test.txt
打印一千行【hello 106】在test.txt文件里；
[root@VM-4-9-centos KongQing]# cnt=0; while [ $cnt -le 1000 ] ; do echo "hello 106 [$cnt]"; let cnt++; done > test.txt
[root@VM-4-9-centos KongQing]# cat test.txt

[root@VM-4-9-centos KongQing]#
**cat指令是从第一行打印文本内容！！！
tac是逆序打印文本内容
但是两者不还是会查看大文本，适合小文本或者代码片段！**
11.more指令
语法：more 选项
功能：more命令，功能类似 cat
常用选项：
-n 对输出的所有行编号
q 退出more
举例：
[atong@LiWenTong ~]$ ls -l / | more
total 162
drwxr-xr-x 2 root root 4096 Apr 25 05:39 bin
drwxr-xr-x 4 root root 1024 Apr 25 04:11boot
drwxr-xr-x 9 root root 3820 May 4 23:20 dev
drwxr-xr-x 84 root root 4096 May 5 00:37 etc
[root@VM-4-9-centos KongQing]# more -10 test.txt
# 打印文本的前十行
hello 106 [0]
hello 106 [1]
hello 106 [2]
hello 106 [3]
hello 106 [4]
hello 106 [5]
hello 106 [6]
hello 106 [7]
hello 106 [8]
hello 106 [9]
--More--(0%)
12.less指令（重要）
less 工具也是对文件或其它输出进行分页显示的工具，应该说是linux正统查看文件内容的工具，功能极其强大。 less 的用法比起
more 更加的有弹性。在 more 的时候，我们并没有办法向前面翻， 只能往后面看 但若使用了 less 时，就可以使用
pageup 等按键的功能来往前往后翻看文件，更容易用 来查看一个文件的内容！ 除此之外，在 less
里头可以拥有更多的搜索功能，不止可以向下搜，也可以向上搜
。
语法： less [参数] 文件
功能：
less与more类似，但使用less可以随意浏览文件，而more仅能向前移动，却不能向后移动，而且less在查看之前
不会加载整个文件。
选项：
-i 忽略搜索时的大小写
-N 显示每行的行号
/字符串：向下搜索“字符串”的功能
?字符串：向上搜索“字符串”的功能
n：重复前一个搜索（与 / 或 ? 有关）
N：反向重复前一个搜索（与 / 或 ? 有关） q:quit
less test.txt
使用less查看的时候，可以上下键进行查看
less和more适合查看大文本
可以在光标处输入/然后再输入你想查找的东西即可
13.head指令
head 与 tail 就像它的名字一样的浅显易懂，它是用来显示开头或结尾某个数量的文字区块，head 用来显示档案的 开头至标准输出中，而
tail 想当然尔就是看档案的结尾。
语法： head [参数]... [文件]...
功能：
head 用来显示档案的开头至标准输出中，默认head命令打印其相应文件的开头10行。
选项：
-n<行数> 显示的行数
14.tail指令
tail 命令从指定点开始将文件写到标准输出.使用tail命令的-f选项可以方便的查阅正在改变的日志文件,tail - ffilename会把filename里最尾部的内容显示在屏幕上,并且不但刷新,使你看到最新的文件内容.
语法： tail必要参数[文件]
功能： 用于显示指定文件末尾内容，不指定文件时，作为输入信息进行处理。常用查看日志文件。
选项：
-f 循环读取
-n<行数> 显示行数
举例：（简单讲解重定向和管道）
有一个文件共有100行内容，请取出第50行内容<br>
seq 1 100 > test # 生成1到100的序列装入test
方法1 head -n50 test > tmp #将前50行装入临时文件tmp
tail -n1 tmp #得到中建行
方法2 head -n50 test | tail -n1【取前三和后三】
[root@VM-4-9-centos KongQing]# less test.txt
[root@VM-4-9-centos KongQing]# head -3 test.txt
hello 106 [0]
hello 106 [1]
hello 106 [2]
[root@VM-4-9-centos KongQing]# tail -3 test.txt
hello 106 [998]
hello 106 [999]
hello 106 [1000]
【输出中间三个】
1.临时文件的方案：
[root@VM-4-9-centos KongQing]# head -101 test.txt > tem.txt
[root@VM-4-9-centos KongQing]# tail -3 tem.txt
hello 106 [98]
hello 106 [99]
hello 106 [100]【>】重定向符将内容写入后面的文本文件中
2.管道：
[root@VM-4-9-centos KongQing]# head -101 test.txt | tail -3
hello 106 [98]
hello 106 [99]
hello 106 [100]
并逆置，提前前三行
最后
十分感谢你可以耐着性子把它读完和我可以坚持写到这里，送几句话，对你，也对我：
1.有时候你可以自私，你不必坚强，你可以哭泣，你可以做任何别人无法理解的事情来发泄你的烦恼(别犯法)，当你休息好，要记得再出发。
2.很多成就，大的成就小的成就，都是在痛苦，挫折，困难中收获的。只做简单的事情，你没法成长也很正常。
3.注意健康，好好活着。来人间一趟不容易。
4.当你害怕时不要退缩，我劝你迎难而上，如果你是个小朋友，在学校被人揍了，一定要当场给我揍回去，但是反击适当，不要太重。哪怕打不过，下一次他揍你之前也会好好想想。如果你不反击，他连想都不会想。
5.如果有一天，让你心动的再也感动不了你，让你愤怒的再也激怒不了你，让你悲伤的再也不能让你流泪，你便知道这时光、这生活给了你什么，你为了成长，付出了什么。
