How the History Is Kept

Feature	Behavior
Scope	The history is per user; every user sees only their own commands
Persistence	It is kept even if the session closes, and the next session continues with the same history
Limit	At most 100 lines are kept; when the limit is exceeded, the oldest lines drop
Repetitions	When the same command is written one after another, it appears once in the history

The following lines are not written to the history: exit, logout and the lines that are interrupted halfway.

Navigating in the History

Shortcut	Its function
↑ ↓	Navigates in the history in order
Ctrl + R	Starts a search in the history; as it is typed the matching command is shown, and when it is pressed again it moves to an older match
→ or End	Accepts the suggestion that appears in grey at the end of the line

During the search the prompt turns into the (reverse-i-search) form; if a match is not found, it writes (failed reverse-i-search).

The grey suggestion

When a command starts to be written, the last command in the history that begins with that text appears in grey in the continuation of the line. It is accepted with → or End; when another key is pressed, it disappears.

Things to Know

• It does not require authorization. Every user who has a session can see their own history.
• Passwords can fall into the history. The password fields that are asked secretly are not written to the history, but the secrets written openly on the command line (such as a client secret key or an LDAP service account password) stay in the history.
• There is no delete command. The history cannot be cleared from the command line; as the records reach the 100-line limit, they drop starting from the oldest.
• Interrupted commands do not count. A line that is left halfway with Ctrl + C is not written to the history.
