43 +== How to take screenshots ==
44 +
45 +Ubuntu 24 provides several convenient keyboard shortcuts for capturing screenshots:
46 +
47 +=== Keyboard Shortcuts ===
48 +
49 +{{{
50 + }}}
51 +
52 +|=Shortcut|=Action
53 +|PrtScn|Capture entire desktop
54 +|Alt + PrtScn|Capture active window only
55 +|Shift + PrtScn|Capture selected area
56 +|Ctrl + PrtScn|Copy screenshot to clipboard
57 +
58 +=== How to Use Area Selection ===
59 +
60 +1. Press Shift + PrtScn
61 +1. Your cursor changes to a crosshair
62 +1. Click and drag to select the area you want to capture
63 +1. Release to take the screenshot
64 +
65 +[[image:attach:Screenshot from 2020-01-22 10-16-28.png||height="250"]]
66 +
67 +Easy to take screenshots of the full Desktop, only the active window or just an area. In area mode your cursor turns into a crosshair and you have to mark the area you want to take a screen of.
68 +
69 +In the above picture i used alt+print, for the following i used shift+print, so you see its just an area:
70 +

72 +
73 +
74 +== How to change colors in terminal ==
75 +
76 +In the Terminal click on "Edit" → "Preferences". A new window opens and there you click on the tab "Profiles". After this click on "Edit" to change the used profile:
77 +
78 +[[image:attach:Screenshot from 2020-01-22 10-18-49.png||height="250"]]
79 +
80 +In the tab "Colors" you can change the colors from system themed to your own favorite:
81 +
82 +[[image:attach:Screenshot from 2020-01-22 10-19-13.png||height="250"]]
83 +
84 +In my case on my computer i use green text and black background with a much more colored stuff [[image:http://confluence.desy.de/s/en_US/7901/4635873c8e185dc5df37b4e2487dfbef570b5e2c/_/images/icons/emoticons/smile.svg||border="0" title="(smile)" class="emoticon emoticon-smile"]]
85 +
86 +[[image:attach:Screenshot from 2020-01-24 09-06-40.png||height="112"]]
87 +
88 +(One can edit some coloring-the-terminal stuff in the .bashrc, too! But this isn't the topic in here [[image:http://confluence.desy.de/s/en_US/7901/4635873c8e185dc5df37b4e2487dfbef570b5e2c/_/images/icons/emoticons/smile.svg||border="0" title="(smile)" class="emoticon emoticon-smile"]])
89 +
90 +
91 +== How to run the Shell as a login shell ==
92 +
93 +In the editing Profile Windows (see picture above) click on the Tab "Command" and check the "Run command as a login shell":
94 +
95 +[[image:attach:Screenshot from 2020-01-22 10-19-44.png||height="250"]]
96 +
97 +To see if you are running with or without login you can use the command "echo $0":
98 +
99 +[[image:attach:Screenshot from 2020-01-22 10-20-29.png]]
100 +
101 +The "-" implicates that it is a login shell. At example you need the login shell to use all your own variables. If you just change user etc. without it, it may happen that - at example - you don't have permissions to geht dconf work because of some variables still got owned by the previous user.
102 +
103 +
104 +== Additional Tips ==
105 +
106 +=== Terminal Best Practices ===
107 +
108 +* Use Ctrl + C to cancel running commands
109 +* Use Ctrl + Z to suspend processes (resume with fg)
110 +* Use history to view command history
111 +* Use Tab for auto-completion
112 +
113 +=== File System Navigation ===
114 +
115 +* Use pwd to show current directory
116 +* Use ls -la for detailed file listings
117 +* Use cd - to return to previous directory
118 +
119 +=== Getting Help ===
120 +
121 +* Use man <command> for manual pages
122 +* Use <command> ~-~-help for quick help
123 +* Use apropos <keyword> to find related commands
