今天讀完 鳥哥的 Linux 私房菜 -- 第 3 堂課：檔案管理與 vim 初探

學會cd目錄也可以按tab鍵可以自動補齊 (死菜鳥XD)
備註 : 空白字元的檔名會自動在前加上\

test@test:~$ mkdir "demo folder"
test@test:~$ cd de #這時候按tab
test@test:~$ cd demo\ folder/ #自動展成這樣

如何刪除目錄,只需要在rm之後加上-rf

test@test:~$ rm demo
rm: cannot remove 'demo': Is a directory
test@test:~$ rm -rf demo

學會除了ls外,還可以使用ll查看目錄下文件,可以額外看到建立時間、大小

test@test:~$ cd demo\ folder/
test@test:~/demo folder$ touch a1.md
test@test:~/demo folder$ touch a2.md
test@test:~/demo folder$ touch b1.md
test@test:~/demo folder$ touch b2.md
test@test:~/demo folder$ ls
a1.md  a2.md  b1.md  b2.md
test@test:~/demo folder$ ll
total 8
drwxrwxr-x 2 test test 4096 Sep 13 11:42 ./
drwxr-xr-x 6 test test 4096 Sep 13 11:38 ../
-rw-rw-r-- 1 test test    0 Sep 13 11:42 a1.md
-rw-rw-r-- 1 test test    0 Sep 13 11:42 a2.md
-rw-rw-r-- 1 test test    0 Sep 13 11:42 b1.md
-rw-rw-r-- 1 test test    0 Sep 13 11:42 b2.md

快速創建100個文件,好爽!

test@test:~/demo$ touch test{1..100}.md
test@test:~/demo$ ls
test100.md  test25.md  test40.md  test56.md  test71.md  test87.md
test10.md   test26.md  test41.md  test57.md  test72.md  test88.md
test11.md   test27.md  test42.md  test58.md  test73.md  test89.md
test12.md   test28.md  test43.md  test59.md  test74.md  test8.md
test13.md   test29.md  test44.md  test5.md   test75.md  test90.md
test14.md   test2.md   test45.md  test60.md  test76.md  test91.md
test15.md   test30.md  test46.md  test61.md  test77.md  test92.md
test16.md   test31.md  test47.md  test62.md  test78.md  test93.md
test17.md   test32.md  test48.md  test63.md  test79.md  test94.md
test18.md   test33.md  test49.md  test64.md  test7.md   test95.md
test19.md   test34.md  test4.md   test65.md  test80.md  test96.md
test1.md    test35.md  test50.md  test66.md  test81.md  test97.md
test20.md   test36.md  test51.md  test67.md  test82.md  test98.md
test21.md   test37.md  test52.md  test68.md  test83.md  test99.md
test22.md   test38.md  test53.md  test69.md  test84.md  test9.md
test23.md   test39.md  test54.md  test6.md   test85.md
test24.md   test3.md   test55.md  test70.md  test86.md

批量刪除目錄底下文件

test@test:~/demo$ touch test{1..100}.md
test@test:~/demo$ rm *
test@test:~/demo$ ls

顯示檔案內容

test@test:~/demo$ vi test.md
test@test:~/demo$ cat test.md # 全顯示
#1,2,3...20
test@test:~/demo$ head test.md # 只列出檔案最前面 10 行
#1,2,3...20

查看檔案的類型

test@test:~/demo$ file test.md
test.md: ASCII text

移動檔案mv

test@test:~/demo$ mkdir demo2
test@test:~/demo$ ls
demo2  test.md
test@test:~/demo$ mv test.md demo2
test@test:~/demo$ ls
demo2
test@test:~/demo$ ll demo2
total 12
drwxrwxr-x 2 test test 4096 Sep 13 12:06 ./
drwxrwxr-x 3 test test 4096 Sep 13 12:06 ../
-rw-rw-r-- 1 test test   58 Sep 13 11:59 test.md

阿~~~ 又是水的一天,大家周末快樂
