🛠️ Command Line Tips for Boosting Efficiency

Ever found yourself needing to search through your command history? Here are some quick tricks to make your terminal life easier:

🔍 Search History

You can instantly rerun your last command by typing !!. Want to search for a specific command you ran? Pair history with grep:

$ history | grep conda
3 conda activate dnakey
5 history | grep conda

Need only your last few commands? Try using tail:

$ history | tail -n 3
4 history
5 history | grep conda
6 history | tail -n 3

💡 Quick Command Fix
Made a typo in your last command? Use ^oldtext^newtext^ to replace part of it without retyping everything. For example:

$ ^conda^pip^

This reruns the previous command, but with conda replaced by pip.

🧹 Cleaning Up History
Need to delete a specific command from your history? Just specify the line number:

$ history -d <line number>

Or clear your entire history file with history -c.

These shortcuts make navigating your command history faster and more efficient.
