Statistically, it is very likely that you have used the same command more than once, however small or large. Once you see the one you want press the return key to run it or press the right arrow key to edit it. If there is more than one relevant command in the history file and the one you need is not the most recent, then just type a few more letters to distinguish the command. All you then need to do is to start typing the command and it will complete the command with the most recent matching command from the history file. This will output a prompt called a reverse-interactive-search.
Again, use less to step through them and or combine it with the down arrow: history | grep -i | less.Īnother useful feature related to history is to use Ctrl + R. The i should be followed by the first letter(s) of the command you are attempting to find. If you think you know the command but can’t quite recall the command exactly, then you can pipe it with grep and the first few letters of that command: history | grep -i. When you find the command you want to run, hit the return key to run it. Helpfully, if you want to rerun a command and can’t quite remember its format, the history facility allows you to simply step through them one at a time by pressing the up arrow (or Ctrl + P) continuously from your command prompt until you find the one you are looking for you can also use the down arrow (or Ctrl + N) to go to the “next” command. If you’d rather not even be bothered with piping with less, just specify the number of commands you want (if you are pretty sure it was a quite recent one): history 25 or history | tail to output the last ten commands. If you know there will be a lot of output, then it makes sense to pipe it to less: history | less with less, you can see the command history one screen at a time (by pressing the spacebar) or one line at a time (by pressing the down arrow). Or, by simply typing history on a command line the terminal will list them. If you want to see them, just open ~/.bash_history and scroll through it. Please note, from the outset, that command history is only saved in interactive shells and does not, therefore, work with shell scripts.īy default, the shell Bash is designed to retain the last five hundred commands you entered. Here are some tips to make the most of the history command. This necessitates some pro-active management to get the best out of it.
