Often times I find myself in need to have the output in a buffer with all the features (scrolling, searching, shortcuts, ...) and I have grown accustomed to
However, most of the commands I use generate output continuously. Using
less with continuous output doesn't really work the way I expected.
while sleep 0.5 do echo "$(cat /dev/urandom | tr -cd 'a-zA-Z0-9' | head -c 100)" done | less -R
less to capture the output until it reaches maximum terminal height and at this point everything stops (hopefully still accepting data), allowing me to use movement keys to scroll up and down. This is the desired effect.
Strangely, when I catch-up with the generated content (usually with PgDn) it causes
less to lock and follow new data, not allowing me to use movement keys until I terminate with ^C and stop the original command. This is not the desired effect.
Am I using
less incorrectly? Is there any other program that does what I wish? Is it possible to "unlock" from this mode?
