Use HISTIGNORE in bash

Don’t you find it annoying when you have been using the same command in bash a few times in a row, and then you scroll through the history to a previous command only having to go through many duplicates of the command you just used.

For this use bash’s HISTIGNORE variable, set in in your ~/.bashrc file.

HISTIGNORE="&"

HISTIGNORE="&"

Will mean you will not have duplicates in your bash history, but you can use other varables too, say you don’t want the commands beggining with c to be put in the history.

An example of this together with not having duplicates:

HISTIGNORE="c*:&"

HISTIGNORE="c*:&"
