TAILF(1) Linux Programmer's Manual TAILF(1)NAMEtailf - follow the growth of a log file
SYNOPSIStailf file
DESCRIPTIONtailf will print out the last 10 lines of a file and then wait for the
file to grow. It is similar to tail -f but does not access the file
when it is not growing. This has the side effect of not updating the
access time for the file, so a filesystem flush does not occur periodi‐
cally when no log activity is happening.
tailf is extremely useful for monitoring log files on a laptop when
logging is infrequent and the user desires that the hard disk spin down
to conserve battery life.
BUGS
An option could be provided to print out the last n lines instead of
the last 10.
