livecmd is an enhanced command history viewer for Linux that organizes your command history in a more useful and readable format. It extends the functionality of the standard history command with powerful filtering, grouping, and display options.
Alphabetical Grouping: Commands are grouped by their first letter for quick scanning
First-Letter Search: Find commands by typing their starting letters
Frequency Analysis: View your most frequently used commands
Timestamps: Optionally display when commands were executed
Colorized Output: Easy-to-read color-coded display
Flexible History Access: View recent commands or your full history

You can customize the tool by modifying these variables at the top of the script:
-
HISTORY_FILE: Path to your history file (default: ~/.bash_history)
-
HISTORY_LENGTH: Number of recent commands to show by default (default: 1000)
-
COLOR_* variables: Change color scheme
-
Bash shell
-
Standard GNU core utilities (awk, sort, grep, etc.)
-
For timestamp support: properly configured HISTTIMEFORMAT
-
Timestamps require proper HISTTIMEFORMAT configuration in bash
-
Currently reads directly from history file rather than using history builtin
-
Limited to bash history (may not work with zsh/fish without modification)
