Examples are as follows, I can't understand.
cp -r/etc/tmp Why don't you use tar.
tar -cvf -/etc | tar -xvf - In contrast to the cp, there's nothing special.
Example eight: after packaging the/etc/directly under/tmp, don't produce a file.
[ root @ ] # ~ cd/tmp
[ root @ ] # -cvf -/etc | tar -xvf - tar
It's a bit like # -r/etc/tmp. ~ is still in its use.
It's important to note where # is in the output file - and the input file becomes - and there's a | existence ~.
#, which represents standard output, standard input and pipeline commands.
