当tar从*.tar.gz提取文件时，我不会限制写入速度。
现在，我可以将文件提取到stdout，并使用pv限制速度，但是如何从stdout恢复文件呢？
是否有更好的方法来实现这一目标？
答案 0 :(得分：0)
使用 lhs op rhs est.std se z pvalue
对tar文件的读取进行速率限制，并将TTB<-c(117,173,159,50.4,99.7,116,202,122,143,105,94.9,70.6,112,252,150,468,240,183,140,140,168,116,178,172,163,150,92.8,74,84.3,144,183,193,222,128,121,137,109,136,78.1,113,92.4,106,99,111,127,90,152,47.7,134,230,115,292,153,209,69.4,155,161,196,186,143,233,255,130,86.9,215,191,182,35.6,150,79.5,113,94.2,46.4,148,101,114,108,102,141,110,116,139,171,153,172,123,159,335,165,259,152,159,142,155,111,236,166,164,157,198,485,296,191,415,294,327,98.7,169,392,256,355,428,458,255,295,321,387,462,271,497,287,257,442,235,506,274,322,163,278,451,148,459,196,323,322,333,436,393,341,406,339,203,226,466,216,296,268,222,384,230,267,309,217,395,348,456,243,381,290,311,285,176,266,355,394,325,214,398,289,139)

的输出传输到pv：
pv请注意，指定tar将导致pv -L ... tarfile.tar.gz | tar -xvzf -
从标准输入中读取。
这限制了读取压缩 tar文件的速度。那可能不是您想要的。这将限制未压缩数据馈送到-f -的速度，并且可能更好地限制tar写入磁盘的速率：
tar请注意，此tar的调用没有zcat tarfile.tar.gz | pv -L ... | tar -xvf -
选项。
