Change KDE Konsole Line Spacing
If you can't use the gui to change the line spacing in KDE Konsole, you can edit the profile file directly. Edit the
file ~/.local/share/konsole/<profile_name>.profile
and add the following line to the Appearance section:
LineSpacing[$i]=3
The last value is the number of pixels you want to add to the line spacing. For example, if you want to add 2 pixels to the line spacing, you would add the following line to the Appearance section:
[Appearance]
ColorScheme=InspiredGithub
Font=Liberation Mono,10,-1,5,50,0,0,0,0,0
LineSpacing[$i]=2
