== Opções ==

* '''-c, --bytes=[+]NUM''': output the last NUM bytes; or use -c +NUM to output starting with byte NUM of each file

* '''-f, --follow[={name|descriptor}]''': output appended data as the file grows;an absent option argument means 'descriptor'

* '''-F''': o mesmo que --follow=name --retry

* '''-n, --lines=[+]NUM''': output the last NUM lines, instead of the last 10; or use -n +NUM to output starting with line NUM

* '''--max-unchanged-stats=N''': with --follow=name, reopen a FILE which has not changed size after N (default 5) iterations to see if it has been unlinked or renamed (this is the usual case of rotated log files); with inotify, this option is rarely useful.

* '''--pid=PID''': with -f, terminate after process ID, PID dies

* '''-q, --quiet, --silent''': never output headers giving file names

* '''-retry''': keep trying to open a file if it is inaccessible

* '''-s, --sleep-interval=N''': with -f, sleep for approximately N seconds (default 1.0) between iterations; with inotify and --pid=P, check process P at least once every N seconds

* '''-v, --verbose''': always output headers giving file names.

* '''-z, --zero-terminated''': line delimiter is NUL, not newline

* '''--help''': display this help and exit

* '''--version''': output version information and exit
