It is well described in the Gnome wiki, quoting:
You can do this with the GSettings key, org.gnome.shell.enabled-extensions, or several tools that manipulate this GSettings key, such as GNOME Tweak Tool or a recent version of gnome-shell-extension-tool.
If you invoke gnome-shell-extension-tool --help
, you will see that it is capable of enabling and disabling extensions by their name. For example, the following command enables user themes:
gnome-shell-extension-tool -e user-theme
Oh, and you can get the names of all your locally installed extensions by doing ls ~/.local/share/gnome-shell/extensions
. It will give you entries of the form the-name@author
.
You can use sleep
and clear
commands in your script as following:
for word in $(< read)
do
echo "$word"
sleep 1
clear
done
Explanation:
The sleep
command make delay for a specified amount of time (in seconds). With sleep 1
delay would be for 1 second. You can change for more time delay by incrementing the second parameter or for delaying less than 1 second divide it to low units; Like sleep .1
for 1/10 second delay or sleep .001
for 1/1000 second delay and etc.
The clear
command clear the terminal screen.
Even better you can do this through below awk
command:
awk '{i=1; while(i<=NF){ print $((i++)); system("sleep 1; clear") }}' read
Explanation:
In awk
, the NF
specifies the total number of fields in the current input record/line, so by using a variable as a counter (i
) and looping over it, we are printing all of them from 1st position to the end of them (NF
). Then by using the system("sleep 1; clear")
part, we are telling to awk
to calling the system commands to sleeping for 1 second and clearing the screen.
In above we are displaying the input file as word by word. If you are going to display it line by line add IFS=$'\n'
in the script like:
IFS=$'\n'
for word in $(< read)
do
echo "$word"
sleep 1
clear
done
And change the awk
command like:
awk '{ $0; system("sleep 1; clear") }1' read
$0
specifies the current line. and the 1
on end enables the default awk
's print command.

This will output the 3rd line, regardless of content.
