I'm looking through some of the scripts that are on the servers and came across an 80MB shell script. Naturally curious I decided to look in there and came across this line:tail +4802 $0 |zcat - |(cd $LANG_TMP && tar -xf - loc/$LANGPRE$LANGPOST.po loc/poextract)  >>/dev/null 2>>/dev/nullCan someone give me a general gist of what this line is supposed to do? I've never seen a tail + command before, usually it's tail -. 
Can someone explain this tail + line to me?
shell script;tail
Using a plus means start printing from the nth line from the beginning of the file.so +4802 will print from line 4802 till the end.man tail gives you a manual page.
