qq 資料夾下的檔案

$ ls qq
c.txt  d.txt  f.txt  q.txt

壓縮資料夾

$ gzip -r qq
$ ls qq
c.txt.gz  d.txt.gz  f.txt.gz  q.txt.gz

壓縮單檔

$ gzip qq.log
$ ls
$ qq.log.gz

解壓縮

$ gzip -rd qq
$ ls qq
c.txt  d.txt  f.txt  q.txt

gzip僅能壓縮單一檔案

tar

  • -z, –gzip, –gunzip, –ungzip filter the archive through gzip
  • -v, –verbose verbosely list files processed
  • -f, –file=ARCHIVE use archive file or device ARCHIVE

壓縮 qq 資料夾成 qq.tar.gz

tar -zcv -f qq.tar.gz qq

-c, –create create a new archive

查看 qq.tar.gz 裡有哪些檔案

tar -ztv -f qq.tar.gz

-t, –list list the contents of an archive

解壓縮 qq.tar.gz

tar -zxv -f qq.tar.gz

-x, –extract, –get extract files from an archive

解壓縮到 /tmp

tar -zxv -f qq.tar.gz -C /tmp
qq/
qq/d.txt
qq/c.txt
qq/f.txt
qq/q.txt
  • -C, –directory=DIR change to directory DIR
  • 原本的qq目錄也還會在

exclude 忽略檔案或資料夾

tar -zcv -f test.tar.gz test --exclude '.git*' --exclude 'cli.php'

忽略 .git 及 cli.php

gunzip

解壓縮 .gz 的檔案

gunzip access.log-20170725.gz

解壓縮 .zip 無法使用 targzip 來解壓縮

必須使用 zip / unzip 做

安裝 :

sudo apt-get install zip unzip

解壓縮 :

unzip weibo-phpsdk-v2-2013-02-20.zip -d qq

解壓縮並放在 qq 資料夾裡, 如果不加上 -d qq 檔案就會散落在目前資料夾

壓縮 :

zip -r qq.zip qq
  • 將 qq 資料夾壓縮成 qq.zip
  • -r : recurse into directories
