Problem

You want to remove a certain line from your server’s bash history, if for example you pasted a password in the wrong place.

Solution

Use the two steps:

1. history -d line_number to remove from memory
2. history -w to write in-memory history to the history file ~/.bash_history

as described here

When the shell is not bash (sh) you can remove them from ~/.ash_history and then source the file.
