The belt and braces method is to not let shell see the list

Assuming that you want to remove qfr* (not dfr*) and that the directory does not contain subdirectories containing files which you do not want do delete. if your "find" does not have "-print", then omit the parameter.

Code:
find . -type f -name qfr\* -mtime +5 -print | while read FILENAME
do
       # Remove echo after testing
       echo rm "${FILENAME}"
done

Try with the "echo" in first to check that the list of commands is suitable.
The "-mtime +5" parameter is designed to avoid deleting anything created in the last 5 days.

pegasus-remove

PEGASUS-REMOVE(1)														 PEGASUS-REMOVE(1)

NAME

       pegasus-remove - removes a workflow that has been planned and submitted using pegasus-plan and pegasus-run

SYNOPSIS

       pegasus-remove [-d dagid] [-v] [rundir]

DESCRIPTION

       The pegasus-remove command remove a submitted/running workflow that has been planned and submitted using pegasus-plan and pegasus-run. The
       command can be invoked either in the planned directory with no options and arguments or just the full path to the run directory.

OPTIONS

       By default pegasus-remove does not require any options or arguments if invoked from within the planned workflow directory. If running the
       command outside the workflow directory then a full path to the workflow directory needs to be specified or the dagid of the workflow to be
       removed.

       pegasus-remove takes the following options:

       -d dagid, --dagid dagid
	   The workflow dagid to remove

       -v, --verbose
	   Raises debug level. Each invocation increase the level by 1.

       rundir
	   Is the full qualified path to the base directory containing the planned workflow DAG and submit files. This is optional if
	   pegasus-remove command is invoked from within the run directory.

RETURN VALUE

       If the workflow is removed successfully pegasus-remove returns with an exit code of 0. However, in case of error, a non-zero exit code
       indicates problems. An error message clearly marks the cause.

FILES

       The following files are opened:

       braindump
	   This file is located in the rundir. pegasus-remove uses this file to find out paths to several other files.

ENVIRONMENT VARIABLES

       PATH
	   The path variable is used to locate binary for condor_rm.
