十、文件搜索名
1. 显示当前目录下“pl.c”文件中包含"linux”的行
2. 在当前目录下新建三个文件，分别为abl.c、ab2.c、ab3.c
[root 回local host ~] # Is .
anaconda- ks.cfg install.log install.log.syslog
[root回localhost ~ # touch abl.c ab2.c ab3.c
root回localhost ~ # Is
abl.c ab2.c ab3.c anaconda- ks.cfg install.log install.log.syslog十一、创建目录
1. 在当前目录创建一个权限为所有者有读、写、执行权限，所有组及其他 人均为可读权限的目录，名为ddd.
root回localhost# mkdir
roo 诡local host ~] # Is -1 总用量88

十二、修改当前目录
1. 返回当前目录的父级目录
[root@localhost # pwd
/ root
root回localhost ~] # cd ..
root 回local host /] # pwd
/ -
2. 切换目录到/usr/tmp
[root@localhost /] # pwd
/root 回local host /] # cd /usr/tmp root@localhost tmp] # pwd
/usr/tmp十三、查看当前目录
I. 查看当前所在目录
[root@localhost tmp] # pwd
/usr/tmp十四、用户切换命令
1. 将当前用户切换为超级用户
文件(F)编辑(E)查看(V)搜索(S)终端(T)帮助(H)
| leila@lGilapc ~] $ su - 密码：
| root@leilapc ~| # Is - a
2. 新建一用户名为linux,并修改用户密码十五、关闭系统
1. 重启系统
2. 立刻关闭系统十六、压缩文件
1. 压缩/opt/folderl下的名为“filel”的文件，要求压缩之后文件的后缀为.gz
[root@localhost opt] # Is /opt/folderl filel
root 回local host opt # gzip /opt/folderl / filel root@localhost opt # Is /opt/folderl
filel.gz
2. 当前位于/opt/folderl b",用zip压缩当前目录下所有文件，并生成名为
folder.zip的压缩目录
root 回local host opt] # cd /opt/folderlroot®localhost folded] # zip folder, zip 米 adding: filel. gz (deflated 19%)
[root 回local host folded] # Is
filel.gz folder.zip十七、打包文件
1.将当前目录下三个目录folder 1folder2> folder3及两个文件abl.c^
ab2.c打包归档，并同时进行压缩[root回localhost opt] # abl.c ab2.c folderl [root回localhost opt] # c
[root回local host opt] # abl.c ab2.c folderl
[root回localhost opt] # abl.c ab2.c folderl [root回localhost opt] # c
[root回local host opt] # abl.c ab2.c folderl

[root回localhost opt] # abl.c ab2.c folderl [root回localhost opt] # c
[root回local host opt] # abl.c ab2.c folderl
Is
folder2 folder3tar - cj f mytarl. tar. bz2 folded folder2 folder? abl. cIs
folder2 folder3 mytarl.tar.bz2
2. 解压当前目录下名为mytarl.tar.bz2的压缩tar包
[root 回local host opt] # Is
abl.c ab2.c folderl folder2 folder3 mytarl.tar.bz2 [root@localhost opt] # tar - xj vf mytarl. tar. bz2 folderl /
folderl / folder, zip
folderl / filel. gz
folder2 /
folder3 /
abl. c
