Linux [11] -- Recap Linux Basic Command

I.Intro

生产实习期间，选的 Big Data，昨天刚搭完hadoop环境，今天想乘机把Linux命令行捡回来，做了一点小小的小练习巩固巩固~ ?

II.Get Started

make three directory name by music, picture, video

 # 文件夹之间用空格隔开Psycho@SheepCore desktop $ mkdir music picture video

snapshot:

fork 18 files under desktop

 # 文件夹之间用空格隔开Psycho@SheepCore desktop $ touch song1.mp3 song2.mp3 song3.mp3 /Psycho@SheepCore desktop $ touch song4.mp3 song5.mp3 song6.mp3Psycho@SheepCore desktop $ touch snap1.jpg snap2.jpg snap3.jpg snap4.jpg snap5.jpg snap6.jpgPsycho@SheepCore desktop $ touch film1.avi film2.avi film3.avi film4.avi film5.avi film6.avi

snapshot:

move all these files into specific folder

 # using mv command to move files from a to bPsycho@SheepCore desktop $ mv ./snap1.jpg ./picturePsycho@SheepCore desktop $ mv ./snap2.jpg ./picture.........

一个一个move太繁琐！！！

So, here is a tremendous way elevate your efficiency:

 # using mv command to move files with operator *Psycho@SheepCore desktop $ mv ./snap*.jpg ./picturePsycho@SheepCore desktop $ mv ./song*.mp3 ./musicPsycho@SheepCore desktop $ mv ./film*.avi ./video# 使用通配符 * 可以批量处理文件，但必须文件名得长得差不多才行！

snapshot:

create three directorys

 # using mkdir to make filefolderPsycho@SheepCore desktop $ mkdir friends family workPsycho@SheepCore desktop $ lsBigData_Hadoop       friends         videobd01_bd02_Linux基础  music           workfamily              picture         ~$164586李久枫.docx

copy files to directorys

 # using cp(copy) commandPsycho@SheepCore desktop $ cp ./music/song{1,2}.mp3 friends/Psycho@SheepCore desktop $ cp ./music/song{3,4}.mp3 family/Psycho@SheepCore desktop $ cp ./music/song{5,6}.mp3 work/Psycho@SheepCore desktop $ cp ./picture/snap{1,2}.jpg friends/Psycho@SheepCore desktop $ cp ./picture/snap{3,4}.jpg family/Psycho@SheepCore desktop $ cp ./picture/snap{5,6}.jpg work/Psycho@SheepCore desktop $ cp ./video/film{1,2}.avi friends/Psycho@SheepCore desktop $ cp ./video/film{3,4}.avi family/Psycho@SheepCore desktop $ cp ./video/film{5,6}.avi work/

snapshot:

remove files and directorys

 # using cp(copy) commandPsycho@SheepCore desktop $ rm -drf ./family ./friends/

remove files in directory but remain directory

 # remove all files in work dir and remain current dirPsycho@SheepCore desktop $ rm -rf ./work/*

snapshot:

using rmdir to remove empty directory

 # using cp(copy) commandPsycho@SheepCore desktop $ rmdir workPsycho@SheepCore desktop $ lsBigData_Hadoop      music           videobd01_bd02_Linux基础  picture         ~$164586李久枫.docx

III. Summary

学而时习之，方可为师也！?

fork a directory: mkdir
fork a file: touch
move files to dir: mv
copy files to another dir: cp ~/oldFile ~/newFolder
remove files and its father directory: rm -rf dirname
remove files but remain dir: rm -rf ~/folderName
remove empty directory: rmdir

Do what you want to do, be what you want to be!
LOVE && PEACE. ?
