Please read the forum rules. You must use a descriptive subject text to post here. Your subject "please help me with this" is not useful to anyone. Everyone here is looking for help, or giving help to someone. Write in a professional way and use a descriptive subject text.

what 'help' do you want ?.

additionally, give the output verbatim generated by running the command on your system pls.

a rough breakdown of your command line ....

sort
-T /fns/$REGION_ID/r/spool # use this directory for any temporary files
-y # obsolete, use -S <amount of memory in kb>
-k 1.21d,1.25d $data/file/SH0000DEP # sort based on field 21 thru 25
-o $data/file/SH0000DEP_sort # put the results into this file
2>$sysout/shsplitdep.log # redirect errors normally posted to stderr to this file

Thanks a lot........
but plz tell why -T is used ..........why we require temporary files or is it optional.

sort needs somewhere to create work file(s) used during its processing, these are usually in /tmp or $TMPDIR, but the option is given to the user to select a 'scratch' area .... so, its optional
