When accidentally pasting a file into the shell it puts a ton of ugly nonsense entries in the bash history. Is there a clean way to remove those entries? Obviously I could close the shell and edit the .bash_history file manually but maybe there's some kind of API available to modify the history of the current shell?


You can use history -d offset builtin to delete a specific line from the current shell's history, or history -c to clear the whole history.

It's not really practical if you want to remove a range of lines, since it only takes one offset as an argument, but you could wrap it in a function with a loop.

rmhist() {
    count=$(( end - start ))
    while [ $count -ge 0 ] ; do
        history -d $start

Call it with rmhist first_line_to_delete last_line_to_delete. (Line numbers according to the output of history.)

(Use history -w to force a write to the history file.)

    Since the OP asked for deleting the N last lines, this script should be modified by doing something like: tot_lines=$(history | wc -l) and then repeat history -d $(( tot_lines - $1 )). – PlasmaBinturong Jan 19 '18 at 9:13

    Instead of $(history | wc -l), there is the variable $HISTCMD that can be used. – PlasmaBinturong Jan 19 '18 at 9:58

Just this one liner in command prompt will help.

for i in {1..N}; do history -d START_NUM; done

Where START_NUM is starting position of entry in history. N is the number of entries you may want to delete.

ex: for i in {1..50}; do history -d 1030; done

    I wonder why this is not a built-in function already. 'history' is a very old tool. – Petr Gladkikh Aug 1 '16 at 9:23
  • serves the purpose very well, but this command can be seen in history :) – Rajeev Akotkar Nov 26 '18 at 4:12
  • askubuntu.com/a/978276/22866 has a nice way to delete the "delete from history command" from history :-) – HanSooloo Jul 4 at 6:46

The answer by user2982704 almost worked for me but not quite. I had to make a small variation like this.

Assuming my history is is at 1000 and I want to delete the last 50 entries


for i in {1..50}; do count=$((start-i)); history -d $count; done
