How to delete a specific command history and when you enter that "command" that will delete the specific command?
For example, here is my history:
1 ls -l
2 cat > foo.txt
3 ifconfig
4 echo "Hello"
Now, I want to delete the ifconfig
command history which is Number: 3, so I'll do the following command: history -d 3
( which will delete the ifconfig command).
The second one is, I want to delete that command I recently typed (history -d 3)
or in other words, this command will not be remembered in history, so no one can see that I just deleted a specific command history.
To summarize, the ifconfig
command history will be deleted and the recently type history -d 3
command will not be remembered/logged in history.
Thanks!
