Command for reloading file from disk to show changes when using “less?”
In less is there a command for reloading a file from disk, so that less will show any changes made to a file since less was started? This would saving me have to terminate and restart less if I want to see changes to the file I'm viewing.
command-line unix less

So you mean instead of following data appended to a file using something liketail -f -n 200 some_file.txtyou would wantlessto reload the file but only show changed content that could be anywhere in the file? Beginning middle or end?

There are two possibly relevant commands detailed in the fine manual for less(1)
R Repaint the screen, discarding any buffered input. Useful if
the file is changing while it is being viewed.
F Scroll forward, and keep trying to read when the end of file is
reached. Normally this command would be used when already at
the end of the file. It is a way to monitor the tail of a file
which is growing while it is being viewed. (The behavior is
similar to the "tail -f" command.)

R for repaint does reload the file on Linux, but does not work for Mac.
A workaround for Mac is to press hq, which will open the Help page, then quit. It has a side effect of reloading the file.
