Linux command cp and mv as well as-T parameters, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can get something.

Fdisk-l

Df

Ps-aux | grep tomcat

Ps-ef | grep tomcat

Cp copies files and folders in the following ways:

What's the difference between the destination path without a file name and without a file name? if there is no file name, what's the difference between / and no / after the directory?

Source directory / root/d

Target directory. / d (already exists)

Result

Cp-r / root/d. / d (. / dUnip d)

Cp-r / root/d. / d / (. / dUnip d)

Cp-r / root/d/. / d (. / dUnip d)

Cp-r / root/d/. / d / (. / dUnip d)

If the parameter-T is added, the execution result is consistent with the following situation

Source directory / root/d

Target directory. / d (does not exist)

Result

Cp-r / root/d. / d (. / d)

Cp-r / root/d. / d / (. / d)

Cp-r / root/d/. / d (. / d)

Cp-r / root/d/. / d / (. / d)

If you add the parameter-T, the behavior does not change.

It is recommended that in any case, add the parameter-T to avoid the uncertainty caused by the existence of the target directory.

Move command

Mv-fT / root/d/. / d /

When using this command, it is best to add the parameter-fT, which can avoid the uncertainty caused by the existence of the target directory.
