These are tools/configurations I use on either a frequent, or regular enough basis to warrant including them on new development machines.

# ~/.bashrc

set -o vi                                    # Set interactive shell to Vim mode

if [[ ":$PATH:" != *":$HOME/bin:"* ]]; then  # Add `~/bin` to `PATH` if not already there
    export PATH="$HOME/bin:$PATH"
fi

tmux

Site: Home · tmux/tmux Wiki · GitHub

In the past I used different terminal emulators (e.g. Terminator, kitty) with their own shortcuts, but I’ve circled back to just tmux in whatever emulator is most easily accessible.

set -g default-terminal "tmux-256color"
set -ag terminal-overrides ",xterm-256color:RGB"

# Use vi-style key bindings in copy mode
set-window-option -g mode-keys vi

# Use vi-style key bindings in the status line (command prompt)
set -g status-keys vi

Refer to my tmux page for more.

#!/usr/bin/env python3

# This script will give you a count breakdown of your PATH paths.

import os

from collections import Counter


path_variable = os.environ.get('PATH')

if path_variable:
    paths = path_variable.split(':')
 
    path_counter = Counter(paths)
 
    for path, count in sorted(path_counter.items()):
        count = f'~ {count} ~' if count > 1 else str(count)
        print(f'{path:50} : {count:^5}')
else:
    print('No PATH!')
