How to Show Hidden Files in Linux
Use ls to show hidden files and directories, including .env and .git.
Linux treats names beginning with a dot as hidden for normal directory listings. They are still ordinary filesystem entries, and `ls -a` reveals them.
Step by step
1 Show hidden names
$ ls -aIncludes hidden entries such as .env, .git and .config.
2 Show details too
$ ls -laCombines hidden entries with long-format permissions, owner, size and timestamps.
3 Include hidden entries but not . and ..
$ ls -AUseful when you want dotfiles without the current and parent directory entries.
4 Inspect one hidden file
$ ls -l .envYou can address a hidden file directly even though it does not appear in a normal `ls` listing.
Tips worth knowing
- Do not expose secrets accidentally when copying or publishing a directory.
- Use `ls -ld .config` when you want information about the directory itself.
- Hidden does not mean protected: permissions still control access.
Frequently asked questions
Why does ls not show .env?
Names beginning with `.` are omitted by default. Use `ls -a` or `ls -la`.
What is the difference between ls -a and ls -A?
`-a` includes `.` and `..`; `-A` includes hidden entries but omits those two special directories.
