how often does the letter "h" occur in:
q: directories cease to exist while using tmux when i connect via ssh to a terminal at work i need to keep sessions alive to run various scripts. however, i often find that the scripts fail because some directory ceases to exist in the meantime.
for example, i get errors like sh: 0: getcwd() failed: no such file or directory after a few hours, or the folder you are executing pip from can no longer be found if i run pip.
how do i go about solving this issue?

a: easy solution: stay out of volatile directories 
better  solution: built good error handling in your scripts. plenty of if [ -d "$directory" ]; then blocks etc.
