Cat files listed in text file and redirect to new directory with same filename
I have a directory that is restricted and I cannot just copy the files need, but I can cat them and redirect them to a new directory. The files all have the date listed in them. If I perform a long listing and grep for the date (150620) I can redirect that output to a text file. Now I need to take that file and, using a script, cat all of the files listed and redirect the output to a temp directory with the same filename.
I've tried several thing but keep getting errors. I've VERY new to scripting and any help would be appreciated.

gendiff
GENDIFF(1) General Commands Manual GENDIFF(1)
NAME
gendiff - utility to aid in error-free diff file generation
SYNOPSIS
gendiff <directory> <diff-extension>
DESCRIPTION
gendiff is a rather simple script which aids in generating a diff file from a single directory. It takes a directory name and a "diff-
extension" as its only arguments. The diff extension should be a unique sequence of characters added to the end of all original, unmodi-
fied files. The output of the program is a diff file which may be applied with the patch program to recreate the changes.
The usual sequence of events for creating a diff is to create two identical directories, make changes in one directory, and then use the
diff utility to create a list of differences between the two. Using gendiff eliminates the need for the extra, original and unmodified
directory copy. Instead, only the individual files that are modified need to be saved.
Before editing a file, copy the file, appending the extension you have chosen to the filename. I.e. if you were going to edit somefile.cpp
and have chosen the extension "fix", copy it to somefile.cpp.fix before editing it. Then edit the first copy (somefile.cpp).
After editing all the files you need to edit in this fashion, enter the directory one level above where your source code resides, and then
type
$ gendiff somedirectory .fix > mydiff-fix.patch
You should redirect the output to a file (as illustrated) unless you want to see the results on stdout.
