Hi everyone,
I have a CLI application that produces lots of output to the
terminal, so I like to send the output along to the "less" command.
This has always worked very nicely. Moving to the top or bottom of
the output used to require just hitting the "home" or "end" key, and
the up and down arrows as well as page up and page down worked nicely.
After upgrading to Hardy on Kubuntu, the behavior changed. Now, it
seems to preempt the navigation and instead print ugly codes for each
press on a "navigational key" (one of those mentioned above), such as
^[OF. When I press "enter", the desired scroll is executed. Scrolling
up and down is one thing, but it's particularly a pain when trying to
search through the output, as it would no longer look up previous
search arguments.
I thought at first it's a problem with Konsole, my terminal program,
or with "less" itself. But I've now tried in different terminal
programs, and reading output other than output from PHP, and the ONLY
time it happens is when I pipe output from PHP to "less". I have
added a small test script that exhibits the problem on my system. It
may work well the first time, but when repeating the same command a
second time, the "weird" behavior starts.
It could very well be some kind of problem with "less", but since I
can only reproduce the problem with output from PHP CLI, I thought
it's worth asking here.
Did something about PHP CLI output change lately?
This has nothing to do with PHP. The keystrokes are processed by less
so your problem lies there or more likely with the terminal emulation
you're using. Please try a more relevant list.

I agree the keystrokes are processed by less. This is probably more a
problem with "less". Yes I will ask on other lists as well.
I thought it was irrelevant to PHP until I tried to provoke the same
behavior by reading large files or other console input. Nope, only PHP
output does it, so I figured someone here might have encountered this
behavior too.
