What is a linux ._ file?

In Linux, files starting with a dot are hidden files and require the -a parameter to be displayed and listed.

There are no restrictions when opening the specified file name.

Usually used to store system log records (.bash_history), service configuration files (.htaccess), and temporary files (vi will create .xxxx.swp files).

There are also some software that will create a directory starting with . to store a series of configuration files and plug-ins (.idea)
