The goal of this assignment is to put in practice the list and I/O
functionalities implemented by Perl.
Write a program that will read a list from a file (input), will sort
the list in lexical order and write back the sorted list to another
file (output). You can use arrays and any of the Perl built-in
functions learned so far to solve this problem.
this it what i have
#!/bin/perl
open ( PWFILE, "/etc/passwd" ) ;
open ( NEWPWFILE , "> /tmp/newpasswd" ) ;
@lines = <HELLO> ; this is how you sort the line;
while ( $line = <PWFILE> ) {
print NEWPWFILE "@line" ;
print @lines
}
close ( PWFILE ) ;
close ( NEWPWFILE ) ;
