bulk renaming with dc

The Double Commander file manager has a tool for quickly bulk renaming a list of files. I tested it out in Kubuntu 17.10, using Double Commander version 0.8.0 beta. The files I wanted to rename were located in my directory named ~/testdirectory, shown here in Double Commander's left panel:

First, I selected the files by clicking Mark > Select All from the toolbar:

That done, I clicked Files > Multi Rename Tool; alternatively, the Ctrl+M keystroke works:

The Multi Rename Tool window looked like this at first:

Here's how I set things up:

Then I clicked the "Rename" button. Result:

Double Commander's Multi Rename Tool is a powerful tool with many options. Users might want to play around with it a bit to get things figured out; for more info, see the "Multi Rename Tool" section in Double Commander's Help document, under 3.1.1 "Files".

automounting with udiskie

This is how udiskie is described here:

udiskie is a UDisks front-end that allows to manage removeable media such as CDs or flash drives from userspace. Its features include:

    - automount removable media when inserted
    - notifications (on insertion, mount, unmount, …)
    - GTK tray icon to manage all available devices
    - command line tools for manual un-/mounting
    - support for LUKS encrypted devices
    - support for unlocking with keyfiles (requires udisks 2.6.4)
    - support for loop devices (mounting iso archives, requires UDisks2)
    - password caching
    - works with either udisks1 or udisks2
    - an extensible code base (python)
    - a maintainer who is open for suggestions;)

All features can be individually enabled or disabled...

I installed udiskie in Arch, to use in Openbox. udiskie puts an icon in tint2's system tray, automounts flash drives when inserted, and provides notifications when flash drives are inserted, mounted, etc.

I'm using the following line in the ~/.config/openbox/autostart file:

udiskie -s &

(According to the man page, that could also be put in ~/.xinitrc.)

That gives me a "smart" icon in the tint2 system tray whenever a flash drive is plugged in:

       -s, --smart-tray
           Show tray icon that automatically hides when there is no action available.

(See man udiskie.)

Shots of the tray icon's left-click and right-click menus:

Also, the following can be used from the command line for mounting and unmounting /dev/sdbx:

$ udiskie-mount /dev/sdbx
$ udiskie-umount /dev/sdbx

tweaking neofetch

Here's a follow-up to an earlier post ("trying neofetch"):

Kubuntu 17.10 has neofetch 3.3.0-1, while the version in Debian Stretch is 2.0.2-1. The older version is nice, but the newer version has some features that make it worth installing, if possible.

Here's a shot of my default neofetch in Kubuntu 17.10:

I found the neofetch configuration file at ~/.config/neofetch/config.conf in Kubuntu 17.10, and at ~/.config/neofetch/config in Debian Stretch. If the user forgets to make a copy of that file, the default file can be found at /etc/neofetch/config.conf in Kubuntu 17.10 or at /usr/share/neofetch/config in Stretch. Also, the default config file for the current neofetch version is at https://github.com/dylanaraps/neofetch/wiki/Config-File.

neofetch's default configuration will be good enough for many users; for others, it's important to study the configuration file and the neofetch manpage, and to refer to the documentation at https://github.com/dylanaraps/neofetch/wiki (and especially: https://github.com/dylanaraps/neofetch/wiki/Customizing-Info).

My current neofetch in Debian Stretch:

And, here's what I have now in Kubuntu 17.10:

I take advantage of the prin function (discussed at https://github.com/dylanaraps/neofetch/wiki/Customizing-Info#prin). For example, here are the lines I used in neofetch's config file in Kubuntu:

prin "$(color 7)Compaq Presario CQ56-219WM Notebook"
prin "$(color 4)Kubuntu 17.10 (Artful)"
prin "$(color 4)KDE Plasma 5.10.5"

In Kubuntu, I also used the "disk" info function -- the one in the newer neofetch version is better than the one in the older version -- and I used the "install_date" info function (which does not appear in the older neofetch version's config file) by uncommenting the following lines:

info "Disk" disk
info "Install Date" install_date

For additional tweaking of those two info functions, I used the following lines further down in the configuration file:

disk_show=('/')
install_time="off"
