当用adb shell进入Android系统后，即可输入linux命令，下面就对一些Andriod常用的linux命令进行汇总!
1.目录与文件
pwd
查看当前完整路径
natrium:/sdcard/MOVIES $ pwd
/sdcard/MOVIES
ls
列出当前目录的所有文件
natrium:/sdcard/MOVIES $ ls
demo.sh dync.mp4 frozen2.mov shalala.mp3 shupin.mp4 static.mp4
ls -alh
以便于阅读的字节单位查看文件详细列表,包括隐藏文件或目录
- a 显示隐藏文件
- l 以行显示
- h 文件大小单位自动转换显示
natrium:/sdcard/MOVIES $ ls -alh
total 92M
drwxrwx--x 2 root sdcard_rw 4.0K 2019-10-24 21:29 . //隐藏目录,上一层
drwxrwx--x 245 root sdcard_rw 8.0K 2019-10-24 20:38 .. //隐藏目录，上上一层
-rw-rw---- 1 root sdcard_rw 26 2019-10-23 08:17 demo.sh

-rw-rw---- 1 root sdcard_rw 1.1M 2019-07-02 19:51 static.mp4
cd
切换路径(change dirtory)
natrium:/sdcard/MOVIES $ cd /sdcard/Android
natrium:/sdcard/Android $ pwd
/sdcard/Android
cd .当前目录cd ..回到上级目录
mkdir
创建一个单层新目录
natrium:/sdcard/MOVIES $ mkdir testdir
natrium:/sdcard/MOVIES $ ls
demo.sh demo2.sh dync.mp4 frozen2.mov shalala.mp3 shupin.mp4 static.mp4 testdir
mkdir -p
创建多级目录
natrium:/sdcard/MOVIES $ mkdir -p ./multidir/testdir2
natrium:/sdcard/MOVIES $ ls
demo.sh demo2.sh dync.mp4 frozen2.mov multidir shalala.mp3 shupin.mp4 static.mp4 testdir
natrium:/sdcard/MOVIES $ cd multidir/ //子级目录被创建
natrium:/sdcard/MOVIES/multidir $ ls
testdir2 //第二层目录被创建
cp
复制文件或目录(copy)
natrium:/sdcard/MOVIES $ cp demo.sh ./testdir/democp.sh //将demo.sh复制到另一目录中并重新命名为demo.cp.sh
natrium:/sdcard/MOVIES $ cd testdir
natrium:/sdcard/MOVIES/testdir $ ls
democp.sh
rm
删除文件(remove)
natrium:/sdcard/MOVIES/testdir $ ls
democp.sh
natrium:/sdcard/MOVIES/testdir $ rm democp.sh
natrium:/sdcard/MOVIES/testdir $ ls
natrium:/sdcard/MOVIES/testdir $
rm -r
删除目录
natrium:/sdcard/MOVIES $ rm -r testdir/
natrium:/sdcard/MOVIES $ ls
demo.sh dync.mp4 frozen2.mov multidir shalala.mp3 shupin.mp4 static.mp4
natrium:/sdcard/MOVIES $
2.文件内容输入与查看
vim
vim helloworld.txt
扫描二维码关注公众号，回复：

打开编辑器并创建一个新文件helloworld.txt,由于手机未带vim编辑器故无示例。
touch
直接生成一个新文件
natrium:/sdcard/MOVIES/multidir $ touch hello.txt
natrium:/sdcard/MOVIES/multidir $ ls
hello.txt testdir2
echo >
向文件中输入内容，如无文件则新建。
natrium:/sdcard/MOVIES/multidir $ echo "Hello World" > helloecho.txt
natrium:/sdcard/MOVIES/multidir $ ls
hello.txt helloecho.txt testdir2
>单个大于号会直接覆盖原有文件内容>>两个大于号会把内容追加到文件末尾，自带换行。
cat
查看文件内容
natrium:/sdcard/MOVIES/multidir $ echo "I am Second Line" >> helloecho.txt
natrium:/sdcard/MOVIES/multidir $ cat helloecho.txt
Hello World
I am Second Line
more
查看文件内容的另一种方式
natrium:/sdcard/MOVIES/multidir $ more helloecho.txt
Hello World
I am Second Line
find
查找特定文件
natrium:/sdcard/MOVIES $ find . -name "*txt" //.表示在当前目录下查找，后缀为txt的所有文件
./multidir/hello.txt
./multidir/helloecho.txt
3.系统信息查看
ps -ef
查看所有进程
natrium:/sdcard/MOVIES/multidir $ ps -ef
