If you only need the filename then there is no need to use the -l flag on ls, which also saves you have to pipe to awk.

Code:
tail `cd path; ls -rt | tail -1`

Using backticks (`) will execute the commands between them and then substitute them with their output. So in the above the name of the most recently modified file in path will be passed as the parameter to tail.

INOTAIL(1)						       Inotify enhanced tail							INOTAIL(1)

NAME
inotail - A fast and lightweight version of tail using inotify SYNOPSIS
inotail [OPTION]... [FILE]... DESCRIPTION
inotail is a replacement for the 'tail' program found in the base installation of every Linux/UNIX system. It makes use of the inotify in- frastructure in recent versions of the Linux kernel to speed up tailing files in the follow mode (the '-f' option). Standard tail polls the file every second by default while inotail listens to special events sent by the kernel through the inotify API to determine whether a file needs to be reread. Note: inotail will not work on systems running a kernel without inotify. To enable inotify, please set CONFIG_INOTIFY=y in your Linux kernel configuration and recompile it. Currently inotail is not fully compatible to neither POSIX or GNU tail but might be in the future. OPTIONS
-c N, --bytes=N output the last N bytes. If the first character of N is a '+', begin printing with the Nth character from the start of each file. -f, --follow keep the file(s) open and print appended data as the file grows -n N, --lines=N output the last N lines (default: 10) If the first character of N is a '+', begin printing with the Nth line from the start of each file. -v, --verbose print headers with file names -h, --help show help and exit -V, --version show inotail version and exit AUTHOR
