Tmux kill pane/window

Kill window/pane in tmux

<Prefix> & for killing a window

<Prefix> x for killing a pane

If there is only one pane (i.e. the window is not split into multiple panes, x would kill the window)

https://stackoverflow.com/questions/7771557/how-do-i-terminate-a-window-in-tmux

Usage for killing tmux windows/pane:

• if nvim freezes during :<,>DiffviewFileHistory or something

Check if a file exists (pre-push example)

Bash

Check existence

lpo() {
  if [[ -f ".git/hooks/pre-push" ]]; then
    echo ".git/hooks/pre-push was found:"
    echo "pre-push is activated"
  else
    if [[ -f ".git/hooks/pre-push.sample" ]]; then
      echo ".git/hooks/pre-push was not found:"
      echo "but .git/hooks/pre-push.sample was found:"
      echo "pre-push is deactivated"
    else
      echo "Hmmmmm"
    fi
  fi
}

Nvim edit file

po() {
  if [[ -f ".git/hooks/pre-push" ]]; then
    echo ".git/hooks/pre-push was found:"
    nvim .git/hooks/pre-push
  else
    if [[ -f ".git/hooks/pre-push.sample" ]]; then
      echo ".git/hooks/pre-push was not found:"
      echo "but .git/hooks/pre-push.sample was found:"
      nvim .git/hooks/pre-push.sample
    else
      echo "Hmmmmm"
    fi
  fi
}

Lua nvim edit file

function file_exists(name)
   local f=io.open(name,"r")
   if f~=nil then io.close(f) return true else return false end
end

function open_prepush()
  if file_exists(".git/hooks/pre-push") then
    vim.cmd("vsplit .git/hooks/pre-push")
  elseif file_exists(".git/hooks/pre-push.sample") then
    vim.cmd("vsplit .git/hooks/pre-push.sample")
  else
    vim.cmd("echo 'Hmmmmm'")
  end
end

vim.keymap.set("n", "<leader><leader>po", open_prepush, { desc = "Open pre-push a new split" })

git hooks

To activate pre-push, rename .git/hooks/pre-push.sample to .git/hooks/pre-push

Example script:

branch_name=$(git symbolic-ref HEAD 2>/dev/null)

allowed_branch_name="refs/heads/"

allowed_branch_name+="min-branch"

if [ "$branch_name" != "$allowed_branch_name" ]; then
  echo "Current branch: ${branch_name}"
  echo "Allowed branch: ${allowed_branch_name}"
  echo
  echo "You can't push directly to this branch." # also prevents --force-with-lease pushes
  exit 1
fi

should work given that this command:

git symbolic-ref HEAD 2>/dev/null

gives: refs/heads/min-branch

and:

git symbolic-ref HEAD 2>/dev/null | cut -d"/" -f 3

gives min-branch

git reset soft | remove last commit and move code to working dir

git reset --soft HEAD~1
