Linux CP forced overlay

In Linux under the CP command is often used, we often use an operation is: CP-RF source/dest/; But although we use the--force parameter, when the directory has a lot of duplicate name files need to overwrite, but found that the mandatory override parameter does not work, we have to manually enter a lot of yes, when the number of duplicate files, input Yes is the most inefficient thing, let us analyze a problem:

1. First we enter the alias command to see what alias the system has for CP:

Input: Alias | grep CP output: Alias cp= ' Cp-i '

2. Then we use the man CP to find out what role-I parameters

Input: Man CP get:-I,--interactive:prompt before overwrite;

This is clear, the original is the system to the CP has an alias, and then this alias added a each before the manual confirmation of the parameters--interactive, the next to the right remedy, the solution has the following several as a reference:

I. Remove aliases you can use the Unalias CP to temporarily remove the CP alias, or you can use the \cp-rf source/dest/way to cancel the alias

Two. Mandatory overwrite is the need to enter Yes, then we'll give you yes. Yes | CP-RF source/dest/, OK
