Linux CP command exception

Linux general technology-Linux technology and application information. For details, refer to the following section. When using the Linux cp command, copy all the content in a folder to the command directory:

For example: cp-rf ezmlm-idx-0.443/* ezmlm-0.53/

The result reminds me every time to overwrite the file. It's strange!

Later I used it: which cp.

Alias cp = 'cp-I'
/Bin/cp

The original cp is the alias of "cp-I", so the system automatically assumes-I (interaction prompt parameter) when only cp is used for copying each time, so the above problem occurs.

Solution (3 methods)

1. Edit vi ~ /. Bashrc or vi ~ /Profile

Remove the alias cp = 'cp-I 'section.

2. Input prompt before copying

3. Use/bin/cp directly.
