Shell Programming and Scripting
Is it possible make the shell read functions 1 by 1 and calling an other function?

"Instead having 9,999 functions which do the same thing with slightly different values, just have your function take parameters."
- Well it's a good point and i would do that If I only wanted to do this action on only 1 particular kind of file but having "9.999 functions" allows me to run them all at once. If i don't want to use one I simply comment it. If I have to modify the subdirectory ($VAR) I simply edit the function.
Good point for the $PATH tho hum.. *hides
switched it to $DIR.
"That code couldn't possibly work. '$FILENAME' in single quotes won't expand. 'FILENAME*' won't expand properly either."
- Indeed it's under double quotes in my script, wrote it back while writing this post, editing previous post..
"Why do you have -type d in one and not in the other?"
- To find my "$FILENAME*" directory and delete it. The name of the directory is basicly the same as the filename. It's set in each function.

dbus-uuidgen
DBUS-UUIDGEN(1) User Commands DBUS-UUIDGEN(1) NAME
dbus-uuidgen - Utility to generate UUIDs SYNOPSIS
dbus-uuidgen [--version] [--ensure [=FILENAME]] [--get [=FILENAME]] DESCRIPTION
The dbus-uuidgen command generates or reads a universally unique ID. Note that the D-Bus UUID has no relationship to RFC 4122 and does not generate UUIDs compatible with that spec. Many systems have a separate command for that (often called "uuidgen"). See http://www.freedesktop.org/software/dbus/ for more information about D-Bus. The primary usage of dbus-uuidgen is to run in the post-install script of a D-Bus package like this: dbus-uuidgen --ensure This will ensure that /var/lib/dbus/machine-id exists and has the uuid in it. It won't overwrite an existing uuid, since this id should remain fixed for a single machine until the next reboot at least. The important properties of the machine UUID are that 1) it remains unchanged until the next reboot and 2) it is different for any two running instances of the OS kernel. That is, if two processes see the same UUID, they should also see the same shared memory, UNIX domain sockets, local X displays, localhost.localdomain resolution, process IDs, and so forth. If you run dbus-uuidgen with no options it just prints a new uuid made up out of thin air. If you run it with --get, it prints the machine UUID by default, or the UUID in the specified file if you specify a file. If you try to change an existing machine-id on a running system, it will probably result in bad things happening. Don't try to change this file. Also, don't make it the same on two different systems; it needs to be different anytime there are two different kernels running. The UUID should be different on two different virtual machines, because there are two different kernels. OPTIONS
The following options are supported: --get[=FILENAME] If a filename is not given, defaults to localstatedir/lib/dbus/machine-id (localstatedir is usually /var). If this file exists and is valid, the uuid in the file is printed on stdout. Otherwise, the command exits with a nonzero status. --ensure[=FILENAME] If a filename is not given, defaults to localstatedir/lib/dbus/machine-id (localstatedir is usually /var). If this file exists then it will be validated, and a failure code returned if it contains the wrong thing. If the file does not exist, it will be created with a new uuid in it. On success, prints no output. --version Print the version of dbus-uuidgen AUTHOR
