The home directory is used to store various user files: settings files, program configuration files, user documents, Data, netscape cache, mail, etc. As an ordinary user, you can create a new directory in your home directory to arrange your personal directory structure. Other users will not be able to read your files or write data to your home directory unless you give them the appropriate permissions.

Linux’s home directory is usually represented by a tilde “~”. For example, if the current user's home directory is /home/haicoder, then entering cd or cd ~ or cd /home/haicoder or cd $HOME are equivalent.

This habit originated from the popular Lear-Siegler ADM-3A terminal machine in the 1970s. On this machine, the tilde and "home" key (used to move the cursor to the far left) happened to be on the same key.
