Hi,
If I declare a function inside another function, it overwrites any previously declared function with the same name. This is NOT what I want.
Example:
#!/bin/bash
_test() { echo test; }
_myf() {
# I'm using the same name as the other function.
_test() { echo local test; }... (8 Replies)

xdg-user-dirs-update
XDG-USER-DIRS-UPD(1) User Commands XDG-USER-DIRS-UPD(1)NAME
xdg-user-dirs-update - Update XDG user dir configuration
SYNOPSIS
xdg-user-dirs-update [OPTION...] [--set NAME PATH...]
DESCRIPTION
xdg-user-dirs-update updates the current state of the users user-dirs.dir. If none existed before then one is created based on the system
default values, or falling back to the old non-translated filenames if such directories exists. The list of old directories used are:
~/Desktop, ~/Templates and ~/Public.
If an old configuration exists it is updated with any new default directories. Additionally, any configured directories that point to
non-existing locations are reset by pointing then to the users home directory. This typically happens when the users removed the directory,
so they likely don't want to use it anymore.
On the first run a user-dirs.locale file is created containing the locale that was used for the translation. This is used later by gui
tools like xdg-user-dirs-gtk-update to detect if the locale was changed, letting you to migrate from the old names.
xdg-user-dirs-update is normally run automatically at the start of a user session to update the XDG user dirs according to the users
locale.
OPTIONS
The following options are understood:
--help
Print help output and exit.
--force
Update existing user-dirs.dir, but force a full reset. This means: Don't reset nonexisting directories to HOME, rather recreate the
directory. Never use backwards compatible non-translated names. Always recreate user-dirs.locale.
--dummy-output PATH
Write the configuration to PATH instead of the default configuration file. Also, no directories are created.
--set NAME PATH
Sets the XDG user dir with the given name.
NAME should be one of the following:
DESKTOP
DOWNLOAD
TEMPLATES
PUBLICSHARE
DOCUMENTS
MUSIC
PICTURES
VIDEOS
PATH must be an absolute path, e.g. $HOME/Some/Directory.
FILES
The XDG user dirs configuration is stored in the user-dirs.dir file in the location pointed to by the XDG_CONFIG_HOME environment variable.
ENVIRONMENT
The XDG_CONFIG_HOME environment variable determines where the user-dirs.dirs file is located.
