```
ac () 
{ 
    out=$(/usr/bin/apt-cache search "$@")
    if [ $(($(echo "$out"|/usr/bin/wc -l)+2)) -ge $LINES ]
	then
        echo "$out" | /usr/bin/less
    else
        echo "$out"
    fi
}
export -f ac

Using the $LINES Bash variable, which tells us how many lines our
current terminal is capable of displaying, makes it relatively simple to
decide whether to use a pipe or not. I also adjust the comparison a bit
to account for the prompt.
