Hi pedantik
Welcome to the forum. Please don't use images to post commands and their results.
You can copy text from the terminal by holding down the left mouse button and dragging the mouse.
You can then paste the text by first left clicking  and then center clicking in the destination location.
If you prefer, you can redirect the output of commands to a text file instead:
vlc /home/tc/1.avi > vlcerror.txt 2>&1Now you can copy/paste from the  vlcerror.txt  file you just created.
Please use  Code Tags  when posting commands and responses seen in a terminal. To use  Code Tags  click on the  #  icon
above the reply box and paste your text between the  Code Tags  as shown in this example:

spacing so column aligned data displays properly.
