For our purposes a file is a line of characters. After a bunch of read and/or write operations we need to tell where are we on that line ?
LOCATION = tell FILEHANDLE
We might also want to move within that file
seek FILEHANDLE, OFFSET, WHENCE WHENCE: 0 from beginning of file 1 from current location 2 from end of file OFFSET: +/- number of bytes to move
the important values are:
seek $fh, 0,0; # go to the beginning of the file seek $fh, 0,2; # go to the end of the file
