lathavim / pludi, thank you for your super-fast reply!
DukeNuke2 - apologies for not giving correct subject text!

lathavim / pludi - If I was running either of your commands manually it would work perfectly as I would be able to enter the name of the file I want to modify, however, remember my filename changes each month and I want to automate this.

Using either

sed -e '2,1d' file >file.tmp&&mv file.tmp file
or
perl -ni -e 'print if !/^\s*$/;' file.txt

requires me to enter the filename - but like I said, it changes each month and I want to automate the process. I need the script to actually fill in the filename for me. The file will always start with Myfile, and it will be the only file in the directory starting like this.

I had thought of using

ls Myfile* > nameholder

This creates a file called nameholder, within which is the name of the current months file to be modified.

If I could then somehow get the script to read that file and save the value as a parameter I could then use that parameter in the sed or perl command

sed -e '2,1d' $myfile >file.tmp&&mv file.tmp $myfile

Thanks for your excellent suggestions though.

Any thoughts?

dbix::class::storage::dbi::oracle::wherejoins

DBIx::Class::Storage::DBI::Oracle::WhereJoins(3)	User Contributed Perl Documentation	  DBIx::Class::Storage::DBI::Oracle::WhereJoins(3)

NAME

       DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI).

PURPOSE

       This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax.

SYNOPSIS

       DBIx::Class should automagically detect Oracle and use this module with no work from you.

DESCRIPTION

       This class implements Oracle's WhereJoin support.  Instead of:

	   SELECT x FROM y JOIN z ON y.id = z.id

       It will write:

	   SELECT x FROM y, z WHERE y.id = z.id

       It should properly support left joins, and right joins.	Full outer joins are not possible due to the fact that Oracle requires the entire
       query be written to union the results of a left and right join, and by the time this module is called to create the where query and table
       definition part of the SQL query, it's already too late.

METHODS

       See DBIx::Class::SQLMaker::OracleJoins for implementation details.

BUGS

       Does not support full outer joins.  Probably lots more.
