Tweaking Linux Lite

It takes quite a while to update, for a NetBook the default font was set to 14 points by using: "Appearance"

For Live CD, the username is the upper left hand corner, for example "ubuntu" with a blank password.

Unity Missing After Logon

Refer: https://askubuntu.com/questions/453482/update-to-14-04-unity-is-not-loading-after-i-login-to-the-admin-profile-after

Switch to terminal (CTRL+ALT+F1) then removing the configuration file ~/.config/dconf/user like this :

Note: You may want to back them up before deleting them; however, this is a binary file, so you cannot edit it manually.

$ sudo service lightdm stop
$ rm ~/.config/dconf/user
$ sudo service lightdm start

You can use the following to backup and restore the configurations in the future, and even put them into a repository such as git.

$ mkdir -p ~/Documents/Backups/config/dconf/user.d
$ dconf dump / > ~/Documents/Backups/config/dconf/user.d/complete.conf
$ cat ~/Documents/Backups/config/dconf/user.d/* | dconf load /

Refer: https://askubuntu.com/questions/72070/how-do-i-change-dconf-keys-without-a-gui-for-a-post-install-script

gsettings set com.canonical.indicator.session show-real-name-on-panel false

No, it will not be deprecated. dconf replaced gconf which will be deprecated. gconf can be changed with gconf-editor or gconftool-2. dconf can be changed with dconf-editor or gsettings.

Quick Tutorial to backup and restore the settings:

dconf dump / > ~/.config/dconf/user.d/everything.conf
cat ~/.config/dconf/user.d/* | dconf load /

Remove Chromium from Ubuntu Keyring

Remove keyring dependency with the following:

Try taking the passwords off of your keyring. This would work well for a virtual environment.

  • Open Applications -> Accessories -> Password and Encryption Keys.
  • Click View -> "By keyring"
  • Right-click on the "login" keyring.
  • Select "Change password"
  • Enter your old password and leave the new password blank.

This did not work...

Go to (Unity button)/Passwords and Keys
On tab Passwords choose the proper key (I'd got only one, so you may need to find proper key). Right-click on it and Delete.
Restart Chromium

It'll ask for password --- do not type any and continue.
Choose "Use unsafe storage"

Grep with SubString

Refer: https://stackoverflow.com/questions/38270261/how-to-extract-a-string-from-between-two-patterns-in-bash

Looking for parameter between -Dappdynamics.agent.nodeName= and closing space

$ ps aux | grep -i appdynamics | grep -oP '(?<= -Dappdynamics.agent.nodeName=)[^ ]+'

$ grep -oP '(?<= -Dappdynamics.agent.nodeName=)[^ ]+' input.txt

-o tells grep to only output the matching part(s) of each line.

-P activates support for PCREs (Perl-compatible regular expressions), which support look-behind assertions such as (?<= inet:), which allow a sub-expression (inet:, in this case) to participate in matching, without being captured (returned) as part of the matched string. [^ ]+ then simply captures everything after inet: up to the first space char. (character set [^ ] matches any char. that is not (^) a space, and + matches this set 1 or more times).

Install Latest Version of youtube-dl

Try this instead because youtube-dl no longer seems to work as of September 22, 2024

sudo snap install video-downloader

Check your version with: youtube-dl --version

Try ppa:nilarimogard/webupd8. I do get upgrades every couple of days and I think, according to the message You get, that it should solve/answer Your question. If You did an upgrade from 13.04 to 13.10 You might have forgot (I guess) to update sources-list.d folder, for example, if You used WebUpd8 before.

$ sudo apt-add-repository ppa:nilarimogard/webupd8
$ sudo apt-get update
$ sudo apt-get install youtube-dl

Usage:

$ youtube-dl -f mp4 --output "yourfilename.%(ext)s" https://youtu.be/your-link-here
$ youtube-dl --extract-audio --audio-format mp3 --audio-quality 256 --output "yourfilename.%(ext)s" https://youtu.be/your-link-here

If you are getting a warning about avconv being out of date.

Refer: https://askubuntu.com/questions/563245/avconv-warning-while-downloading-youtube-video

before

$ avconv |& grep \ version | awk '{print $3}'
9.18-6:9.18-0ubuntu0.14.04.1,

$ sudo add-apt-repository ppa:heyarje/libav-11 && sudo apt-get update
$ sudo apt-get install libav-tools

after

$ avconv |& grep \ version | awk '{print $3}'

Issue now requires the enter key to be hit to finish the download
