I'm in an edge situation and I really need to retrieve some generate random value I executed last week in iTerm through the command: cat /dev/urandom |LC_ALL=C tr -dc 'A-Z9' | fold -w 81 | head -n 1

I used this command to create a seed for a new wallet for my virtual coins, I thought I copy it somewhere but I didn't... I can't scroll up to look at this because I reach the maximum buffer limit so... So I was thinking its really possible at this point to recover this value? Some kind of history storing somewhere? Its almost a matter of life or death. I'm using iTerm zsh with MacOS Sierra.

Regards!

  • You can try increasing the limit, see here. However, I'm not sure if it can be done postliminary.

  • Yeah, that's it, only take effects in the very moment it applies...

  • You can check if the .zsh_history file has more lines than the buffer. Maybe not since the previous cahnge didn't work.

  • Pretty useful! But not the output of the command results :(
