How to copy all non hidden files in your current directory with names not beginning with a digit to other directory?

Answer 1

Here we will use the cp command to copy all non-hidden files. and we will copy only those files which are not beginning with a digit and such file we will identify with the help of regex [^0-9]*  

In this regex  ^ symbol in regex is like a not. [^0-9] this indicates not any digit and * indicates all. so we are copying all files which are not starting with a digit by using the following command.

cp [^0-9]* path_of_dir/

path_of_dir is a path where you want to copy all these files.
