       Otherwise MODE is a number which may be followed by one of the
       following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for
       G,T,P,E,Z,Y,R,Q.  Binary prefixes can be used, too: KiB=K, MiB=M, and
       so on.  In this case the corresponding stream will be fully buffered
       with the buffer size set to MODE bytes.

       125    if the stdbuf command itself fails

       126    if COMMAND is found but cannot be invoked

       127    if COMMAND cannot be found

       -      the exit status of COMMAND otherwise

       tail -f access.log | stdbuf -oL cut -d ' ' -f1 | uniq
       This will immediately display unique entries from access.log

BUGS
       On GLIBC platforms, specifying a buffer size, i.e., using fully
       buffered mode will result in undefined operation.
