Boost your productivity by expanding your command history and adding the power of fzf fuzzy search to your terminal.
Why Improve Your Bash History
Enhancing your Bash history gives you:
- Faster command recall
- Shared history across all terminal sessions
- Useful timestamps for every command
Step 1: Enhance Your Bash History
Open your configuration file:
nano ~/.bashrc
Add the following:
# Remove duplicate history entries
export HISTCONTROL=ignoredups:erasedups
# Increase history size
export HISTSIZE=1000000
export HISTFILESIZE=1000000
# Add timestamps
export HISTTIMEFORMAT="%F %T: "
# Sync history across sessions
export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND"
Apply the changes:
source ~/.bashrc
Step 2: Add Fuzzy Search With fzf
fzf enables flexible and fast command searching by matching partial input.
How Fuzzy Search Helps
- Matches partial or out of order characters
- Ranks results by relevance
- Handles slight typos
- Works instantly even with large histories
