Sorting content of file
hi ladies and gents:

can you give me a command to sort content of file and save it to the file itself:

file1
HTML Code:
roy@emerson.com
joy@emerson.com
irish@emerson.com
output would be file1 on same directory:

file1:
HTML Code:
irish@emerson.com
joy@emerson.com
roy@emerson.com

it doesn't work redirecting the output on the same file.

based on "what" you are doing sort here?

It's true that "irish" comes first before "joy"!!! (input file itself is sorted)

Code:
TEST>perl -e '{open (F,"input_file");my @n_s=<F>;close(F);@s=sort(@n_s);open(F,">","input_file");foreach(@s) { print F "$_"; } close(F)}' input_file

Make sure the above works good only for "Alphanumeric" and not for others.

You need to enhance the script, if it needs to work for others.
