pager(1) is the alternative provided by less, more, most, dog, pg and so
on.
sensible-pager is a small shell script:
#!/bin/sh
${PAGER:-pager} "$@"
ret="$?"
if [ "$ret" -eq 126 ] || [ "$ret" -eq 127 ]; then
more "$@"
ret="$?"
if [ "$ret" -eq 126 ] || [ "$ret" -eq 127 ]; then
echo "Couldn't find a pager!" 1>&2
echo "Set the \$PAGER environment variable to your desired
pager." 1>&2
exit 1
fi
fi
So if you set PAGER in your environment, that'll be preferred, else
it'll use pager(1), else it'll fall back to more (since that's in
util-linux, it's guaranteed to be available).
