Here’s a little snippet of Bash code that waits for spacebar to be pressed to continue.
function spacebar { echo 'Press spacebar to continue. Press Ctrl-C to exit.' stty -echo > /dev/null until read -r -n 1 -t 0.001 && [ "$REPLY" = ' ' ]; do abc=''; done stty echo > /dev/null } echo 'Starting upgrade' spacebar |
Output
Starting upgrade Press spacebar to continue. Or Ctrl-C to exit. |
If you press spacebar it will continue. Ctrl-C exits the program.
