Removing duplicates in Bash history
I have a habit of spamming commands when I get impatient. Like this:
374 ssh -v [email protected]
375 ssh -v [email protected]
376 ssh -v [email protected]
377 ssh -v [email protected]
378 ssh -v [email protected]
...
402 ssh -v [email protected]
403 ssh -v [email protected]
404 ssh -v [email protected]
405 ssh -v [email protected]
By default, Bash on macOS doesn’t remove duplicates, so I have to skip
through them when I use the ā key to go back through my history.
Fortunately, I can add one line to my ~/.profile to remove those duplicates.
export HISTCONTROL=ignoredups
