In LINUX Hidden file are start with .(DOT)

if you create files with starting .(DOT), those files are hidden.

You can use chmod to set permissions to the file.

if you set only read only then those cannot be modified in program

chmod 444 filename

if you want to use this from C-language use system() function to execute this command

if You use simple ls -alF you can see those files.

the below files are hidden files In LINUX
