history delete particular lines

My answer is based on previous answers, but with the addition of reversing the sequence so that history items are deleted from most recent to least recent.
Get your current history (adjust the number of lines you want to see):
history | tail -n 10
This gives me something like
1003  25-04-2016 17:54:52 echo "Command 1"
1004  25-04-2016 17:54:54 echo "Command 2"
1005  25-04-2016 17:54:57 echo "Command 3"
1006  25-04-2016 17:54:59 echo "Command 4"
1007  25-04-2016 17:55:01 echo "Command 5"
1008  25-04-2016 17:55:03 echo "Command 6"
1009  25-04-2016 17:55:07 echo "Command 7"
1010  25-04-2016 17:55:09 echo "Command 8"
1011  25-04-2016 17:55:11 echo "Command 9"
1012  25-04-2016 17:55:14 echo "Command 10"
Select the start and end positions for the items you want to delete. I'm going to delete entries 1006 to 1008.
for h in $(seq 1006 1008 | tac); do history -d $h; done
This will generate history -d commands for 1008 then 1007 then 1006.
If I also wanted to delete the history delete command then it's a bit more complicated because you need to know the current max history entry.
You can get this with (there may be a better way):
history | tail -1 | awk '{print $1}'
Putting it together you can use this to delete a range, and also delete the history delete command:
for h in $(seq 1006 1008 | tac); do history -d $h; done; history -d $(history | tail -1 | awk '{print $1}')
Wrap this all up in a function to add to your ~/.bashrc:
histdel(){
  for h in $(seq $1 $2 | tac); do
    history -d $h
  done
  history -d $(history | tail -1 | awk '{print $1}')
  }
Example deleting command 4, 5 and 6 (1049-1051) and hiding the evidence:
[18:21:02 jonathag@gb-slo-svb-0221 ~]$ history | tail -n 11
 1046  25-04-2016 18:20:47 echo "Command 1"
 1047  25-04-2016 18:20:48 echo "Command 2"
 1048  25-04-2016 18:20:50 echo "Command 3"
 1049  25-04-2016 18:20:51 echo "Command 4"
 1050  25-04-2016 18:20:53 echo "Command 5"
 1051  25-04-2016 18:20:54 echo "Command 6"
 1052  25-04-2016 18:20:56 echo "Command 7"
 1053  25-04-2016 18:20:57 echo "Command 8"
 1054  25-04-2016 18:21:00 echo "Command 9"
 1055  25-04-2016 18:21:02 echo "Command 10"
 1056  25-04-2016 18:21:07 history | tail -n 11
[18:21:07 jonathag@gb-slo-svb-0221 ~]$ histdel 1049 1051
[18:21:23 jonathag@gb-slo-svb-0221 ~]$ history | tail -n 8
 1046  25-04-2016 18:20:47 echo "Command 1"
 1047  25-04-2016 18:20:48 echo "Command 2"
 1048  25-04-2016 18:20:50 echo "Command 3"
 1049  25-04-2016 18:20:56 echo "Command 7"
 1050  25-04-2016 18:20:57 echo "Command 8"
 1051  25-04-2016 18:21:00 echo "Command 9"
 1052  25-04-2016 18:21:02 echo "Command 10"
 1053  25-04-2016 18:21:07 history | tail -n 11
The question was actually to delete the last 10 commands from history, so if you want to save a little effort you could use another function to call the histdel function which does the calculations for you.
histdeln(){

  # Get the current history number
  n=$(history | tail -1 | awk '{print $1}')

  # Call histdel with the appropriate range
  histdel $(( $n - $1 )) $(( $n - 1 ))
  }
This function takes 1 argument, the number of previous history items to delete. So to delete the last 10 commands from history just use histdeln 10.
