Combining files with specific patterns of naming in a directory
Greetings Unix exports,
I am facing some problems in combining files with different name patterns with a directory and I would appreciate if you can help me
I have more than 1000 files but they follow a specific pattern of naming. e.g. 64Xtest01.txt
They are divided into two sets of test and train
The Train set pattern is the following: e.g. 64XtrainY1.txt-James-Maggie.txt
Quote:
1) 2 fixed digits: 64
2) A Capital letter which may vary
3) “train”
4) Another Capital letter
5) One digit number
6) “.txt-”
7) Another pattern of “bla-bla” ---25 to 50 different names
8) .txt --- the format
The test set pattern is the following: e.g. 64xtest14.txt-James-Maggie.txt
Quote:
1) 2 fixed digits 64
2) A capital letter which may vary
3) “test”
4) Two digit number, may vary
5) “.txt-”
6) Another pattern of “bla-bla” ---25 to 50 different names
7) .txt --- the format
And each of these files have only one line in them
Now I want to combine the files that have the unique patterns before the “.txt” and combine the rest of the files in them. e.g.
I am wondering what is the best way to deal with it
I have tired to combine all of them into a single file and then divide them best of a line with GREP but that is not an afficient way to do it I am sure.

update-desktop-database
UPDATE-DESKTOP-DATABASE(1) General Commands Manual UPDATE-DESKTOP-DATABASE(1)NAME
update-desktop-database - Build cache database of MIME types handled by desktop files
SYNOPSIS
update-desktop-database [-q|--quiet] [-v|--verbose] [DIRECTORY...]
DESCRIPTION
The update-desktop-database program is a tool to build a cache database of the MIME types handled by desktop files.
The cache database contains the list of MIME types that can be handled by desktop files, as well as, for each MIME type, a list of desktop
files that can handle this MIME type. This cache database ease the work of applications that need to find an application that can open a
document of a specific MIME type: those applications will not have to parse all the desktop files existing on the system, and can instead
parse this cache database.
If no DIRECTORY is specified as argument, the desktop files that will be processed are the ones installed in $XDG_DATA_DIRS/applications.
If both the --quiet and --verbose options are used, then --verbose will be ignored.
OPTIONS
The following options are supported:
-q, --quiet
Do not display any information about processing and updating progress.
-v, --verbose
Display more information about processing and updating progress.
NOTES
If an invalid MIME type is met, it will be ignored and the creation of the cache database will continue.
The format of the cache database is a simple desktop entry format, with a MIME Cache group, containing one key per MIME type. The key name
is the MIME type, and the key value is the list of desktop file that can handle this MIME type.
The order of the desktop files found for a MIME type is not significant. Therefore, an external mechanism must be used to determine what
is the preferred desktop file for a MIME type.
EXAMPLE
Here is a simple example of a cache database:
[MIME Cache]
application/x-shellscript=gedit.desktop;
text/plain=gedit.desktop;gvim.desktop;
video/webm=totem.desktop;
This cache database is created with three desktop files, each containing a MimeType key:
gedit.desktop: MimeType=text/plain;application/x-shellscript;
gvim.desktop: MimeType=text/plain;
totem.desktop: MimeType=video/webm;
FILES
$XDG_DATA_DIRS/applications/mimeinfo.cache
This file is the cache database created by update-desktop-database.
