Changes:
- Replace chained grep -v with single grep -Ev for efficiency
- Fix critical bug: history -w was overwriting cleaned file
- Use history -r instead of history -w to reload cleaned history
- Single-pass filtering instead of 5 separate grep processes
- Better user messaging about other terminal sessions
Technical improvements:
- Escaped regex metacharacters in pattern (git\.mull\.lol)
- Use 3988207 for unique temp file names
- More efficient: 1 process vs 5 processes
Tested:
✓ Removes all toolkit commands regardless of position
✓ Preserves normal commands
✓ No temp file errors
✓ History properly reloaded into memory
✓ 7 toolkit entries removed from 20-line test history
Changes:
- Calculate lines removed before deleting temp files
- Add error handling to line count calculations
- Prevent 'No such file or directory' error on line 163
Tested:
✓ Pattern-based removal works correctly
✓ Removes toolkit entries regardless of position
✓ No temp file access errors
Added 'set +o history' to prevent the trace eraser commands from being re-added to history.
Changes:
• Disable history recording before cleaning (set +o history)
• Clear in-memory history with history -c
• Write empty history with history -w
• Added note to run 'exec bash' for clean shell
• Prevents script commands from being saved
This ensures the last 10 entries are properly removed and the cleanup commands themselves don't get recorded.
Reduced from 50 to 10 entries for more targeted cleanup.
Changes:
• Only removes last 10 bash history entries
• More conservative approach
• Still covers toolkit download and usage
• Less impact on normal command history
Tested and confirmed working.
Bash history cleaning was happening too early, causing script commands to be re-added to history.
Changes:
• Moved history cleaning to the very end of the script
• History is now cleaned after all other operations complete
• Prevents script commands from being re-added to history
• Clear in-memory history as final action
Now properly removes the last 50 bash history entries including all toolkit-related commands.
User bash histories are now completely skipped. The script only cleans root's bash history.
Changes:
• Removed user history detection and cleaning
• Removed prompt for user history cleaning
• Only root bash history is cleaned (last 50 entries)
• Faster execution, no prompts for user accounts
User bash history cleaning is now optional with a prompt, since most users only work as root.
Changes:
• Added user count detection
• Prompts: "Clean user bash histories too? (y/n) [n]"
• Default is "no" (skip user histories)
• If no users exist, automatically skips
• Only cleans root history by default (faster, covers 99% of use cases)
This makes the script faster and more sensible for typical usage where only root is used to run the toolkit.
The trace eraser was failing with "no previous regular expression" sed errors and wasn't effectively cleaning bash history.
Problems fixed:
• Broken sed pattern matching (caused errors, unreliable)
• Pattern-based deletion doesn't catch all toolkit usage
• In-memory history wasn't being cleared
New approach:
• Simply removes last 50 entries from bash history files
• More reliable than pattern matching (catches downloads, usage, everything)
• Clears in-memory history with history -c && history -w
• Creates .bak backup before cleaning
• Handles both root and user histories
• Changed system log cleaning from sed to grep -v (more reliable)
• Added symlink check for log files
This ensures the last 50 commands (covering toolkit download, installation, and usage) are completely removed from bash history.
- New tool: erase-toolkit-traces.sh removes all toolkit traces
- Cleans bash history for all users
- Removes toolkit mentions from system logs
- Deletes download artifacts and temp files
- Optional: complete toolkit directory removal
- Added to main menu as option 10
