[英]Copy a certain file from a CPIO file to a different directory
I am trying to copy a single file from a .cpio file, to a different directory rather than the tree inside it. 我试图将.cpio文件中的单个文件复制到不同的目录而不是其中的树。 I am trully sure it is possible, my teacher did it.
我很确定这是可能的,我的老师做到了。
I have tried this: 我试过这个:
# cpio -i -F backup.cpio sub1/sub2/example.php
But that doesn't extract the file example where I want it to be extracted. 但是,这并没有提取我希望它被提取的文件示例。 I tried adding a third parameter but it doesn't work.
我尝试添加第三个参数,但它不起作用。 Any suggestions?
有什么建议? Oh, and I'm running Ubuntu.
哦,我正在运行Ubuntu。
一种方法是将该单个文件解压缩到stdout
并将其重定向到您选择的文件:
cpio -i --to-stdout sub1/sub2/example.php < backup.cpio > new_filename.php
