tool: D199: Usage: %s [OPTION]... [FILE]


tool: 

tool: D132: Print the last 10 lines of FILE to standard output.

tool: D218: If no FILE given or FILE is -, use standard input.

tool: D20: Options:

tool: D202:   -b         with -r, begin at first matching line, not last.

tool: D159:   -c N       print the last N bytes; -c +N will begin with

tool: D183:              the Nth byte

tool: D111:   -f         continue reading from file as data is appended

tool: D178:   -n N       output the last N lines; -n +N will begin with

tool: D217:              the Nth line

tool: D206:   -r REGEX   output lines beginning with last line matching

tool: D136:              extended regular expression REGEX

tool: D205:   -u REGEX   stop following file when a line matches extended

tool: D119:              regular expression REGEX, and exit.

tool: D81:   --help     display help and exit

tool: D87:   --version  display version information and exit

tool: D102: The -r and -u options take an extended POSIX regular expression as

tool: D212: argument. These expressions are matched against each line without

tool: D135: implicit anchoring. ^ and $ will match the start and end of a line

tool: D0: respectively. -u is meaningful only when joined with -f, and will

tool: D169: output the matching line before terminating.
