README.md

Rudamentary tail implementation.

##Missing features:

Flags with features

  • --bytes : output the last K bytes; alternatively, use -c +K to output bytes starting with the Kth of each file
  • --max-unchanged-stats : 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 : with -f, terminate after process ID, PID dies
  • --quiet : never output headers giving file names
  • --retry : keep trying to open a file even when it is or becomes inaccessible; useful when follow‐ing by name, i.e., with --follow=name
  • --verbose : always output headers giving file names

Others

The current implementation does not handle - as an alias for stdin.

##Possible optimizations:

  • Don't read the whole file if not using -f and input is regular file. Read in chunks from the end going backwards, reading each individual chunk forward.
