Question 1

How do I set up shellclear to run automatically on terminal startup?

Accepted Answer

Add the initialization command (e.g., eval $(shellclear --init-shell)) to your shell's configuration file, such as .bashrc or .zshrc. This will display a summary of sensitive findings each time you open a new terminal, as shown in the MOTD example.

Question 2

Can shellclear detect and remove AWS access keys from history?

Accepted Answer

Yes, shellclear includes patterns for common sensitive data like API keys and tokens. For AWS-specific keys, you may need to add custom patterns using the config command to improve detection accuracy, as the base patterns might not cover all formats.

Question 3

What's the difference between shellclear clear and shellclear stash?

Accepted Answer

Clear permanently masks or removes sensitive entries from history, while stash temporarily clears the entire history file for scenarios like presentations and allows restoration with pop. Stash is useful for temporary privacy without losing data.

Question 4

Is shellclear safe to use on production servers?

Accepted Answer

Shellclear is safe if used cautiously; always create backups with --backup before cleaning to avoid data loss. However, it scans local files only and doesn't integrate with server monitoring tools, so it's best for personal or development use.

Question 5

How to restore shell history if I accidentally cleared it?

Accepted Answer

Use the restore subcommand to recover from backups created with --backup, or if you used stash, run shellclear stash pop. The README details these options to ensure you can undo changes safely.

Question 6

Shellclear vs setting HISTIGNORE in bash: which is better?

Accepted Answer

Shellclear offers automated detection and cleaning with backup safety, while HISTIGNORE only prevents commands from being recorded initially. For auditing existing history, shellclear is superior; for prevention, HISTIGNORE or similar shell settings might suffice.
