It's not entirely clear to me what arguments 2 and 3 are. I argument 3 the number of files being processed and argument 2 the field being sorted on?

I'm sorry for not explaining it better. I thought the usage message comment was sufficient documentation along with the examples I gave. The arguments are:

A pathname of the directory containing the files to be processed.
The field to be used as your sort key.
The maximum number of files you want to list.

Your file names are of the form:

Code:

field1_field2_field3_field4_field5_field6_field7_field8_field9_field10_field11_field12_field13_field14

where field14 always ends with the string .out.txt. I showed you examples using fields 1, 3, and 5 as the sort key since they were the only numeric fields in the names of the files you used in your example that had values that were not a constant. The 12th field was numeric but all filenames had 4 in field12 so sorting on it didn't seem useful.

The count (3rd operand) in my examples was 3 and 5 since you used 3 in your example and you only had 5 files in your example. You can put any number you want there to specify the number of files you want listed. It is happy with 1; it is happy with 32000. Pick the number you want.

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
