abc.xxx.out.remoteOn    FALSE   write
def.xxx.out.remoteOn    FALSE   write
ghi.xxx.out.remoteOn    TRUE    write
jkl.xxx.out.remoteOn    FALSE   write


Thanks Pamu, but it has changed the file format. after change, now only one tab space. while there are around 3 tab spaces before 3rd col and 2 tabs before 2nd col.

guards

GUARDS(1)						User Contributed Perl Documentation						 GUARDS(1)

NAME

       guards - select from a list of files guarded by conditions

SYNOPSIS

       guards [--prefix=dir] [--path=dir2:dir2:...] [--default=0|1]	   [-v|--invert-match] [--list|--check] [--config=file]        symbol ...

DESCRIPTION

       The script reads a configuration file that may contain so-called guards, file names, and comments, and writes those file names that satisfy
       all guards to standard output. The script takes a list of symbols as its arguments. Each line in the configuration file is processed
       separately. Lines may start with a number of guards. The following guards are defined:

	   +xxx Include the file(s) on this line if the symbol xxx is defined.

	   -xxx Exclude the file(s) on this line if the symbol xxx is defined.

	   +!xxx Include the file(s) on this line if the symbol xxx is not defined.

	   -!xxx Exclude the file(s) on this line if the symbol xxx is not defined.

	   - Exclude this file. Used to avoid spurious --check messages.

       The guards are processed left to right. The last guard that matches determines if the file is included. If no guard is specified, the
       --default setting determines if the file is included.

       If no configuration file is specified, the script reads from standard input.

       The --check option is used to compare the specification file against the file system. If files are referenced in the specification that do
       not exist, or if files are not enlisted in the specification file warnings are printed. The --path option can be used to specify which
       directory or directories to scan.  Multiple directories are eparated by a colon (":") character. The --prefix option specifies the location
       of the files.
