在bash中，cp是否在使用通配符时复制点文件？ 我应该使用哪个选项

Question

When I use cp -r source dest, the dot files as in .gitIgnore or any .xyz are ignored. When I use cp -r source/.xyz dest, then they are copied. Which option with cp can copy all the files including the dot files while using the wildcard *?

Answer 1

You can use the wildcard like cp -r .[^.]*

Thats because your bash is built to ignore the hidden files and cp command just don't get the hidden arguments. Thats how its supposed to work .. :)

Answer 2

While using a wildcard * , you can try the command cp source/*.* destination/ to copy all the hidden files too.

If you want to include unhidden directories in the cp command you can try the below command

cp -r source/. destination/

Note the . at the end of source. That includes all the files and directories in the source including hidden ones.

Or

cp -r source/{.,}* destination/

x{.,}y is converted to xy and xy . In your case it will be source/.* and source/*

Answer 3

As for me the most universal way:

cp -a /source/. /destination/

Or if you are inside of a source folder:

cp -a . /destination/
