scp

Posted by 夏泽民 Dec 1, 2019

cp -C应该被认为只是一种方便.如果文件可以被显着压缩,那么最好首先在源上压缩它,传输压缩的表单,最后在目标上压缩 但是只是针对单个文件进行压缩如果是多个小文件最好用 tar -zcvf go1.10.tar ./ $scp go1.10.tar xiaoju@10.96.83.51:/home/xiaoju/goLang/src/github.com/go 使用ssh+tar 传输文件与scp比较 使用cat 输出文件 tar -zcvf - ./ |ssh posp@192.168.3.55 “cat >/home/posp/xxx.tar.gz real 1m26.803s user 1m21.459s sys 0m5.323s 使用dd生成文件 tar -zcvf - ./ |ssh posp@192.168.3.55 “dd of=/home/posp/xxx.tar.gz real 1m27.242s user 1m21.475s sys 0m5.840s 直接在传输的时候直接解压 tar -zcvf - ./ |ssh posp@192.168.3.55 “tar -zxvf - -C /home/posp/trans1” real 1m27.242s user 1m21.475s sys 0m5.840s 使用Scp传输文件(没有压缩) scp -r ./ posp@192.168.3.55:/home/posp/chenchen_test/trans1 real 6m54.000s user 0m41.940s sys 0m12.742s ps: 因为空洞文件压缩后会非常小,没有压缩传输的话非常耗费时间
