[mike]

orion 13-11-2003 mike
jupiter 11-11-2003 susan
venus 12-11-2002 alvin
neptune 10-11-2002 sharon

i just want to sort this file on the first column by string so
eventaully the output is:

jupiter 11-11-2003 susan
neptune 10-11-2002 sharon
venus 12-11-2002 alvin
orion 13-11-2003 mike

Put the data to sort in an array. If you have the data in a file
(data.txt for example), you can do this with:

open(IN,"data.txt") or die("Can't open file");
@array = <IN>;

You can then create a sorted array with:

@sorted_array = sort @array;

FYI: this newsgroup is defunct. Try comp.lang.perl.misc in the future
for better responses.

Why not use the UNIX sort command ?
