Question

I want to run the following (KDE specific) command with an argument (-0.1) that starts with ‘-‘

kdialog --textinputbox 'Output:' '-0.1'

It is suposed to show a textbox with ‘-0.1’ but the command gives

unknown option "-0.1"

while

kdialog --textinputbox 'Output:' '0.1'

works.
Obviously the command tries to interpret 0.1 as an option.
Is there a way to pass the argument “-0.1” to such commands? I tried passing it as variable which didn’t work either!

Answer 1

Try with:

kdialog --textinputbox 'Output:' -- '-0.1'

-- means “end of options” and should work for all Qt (thus KDE) apps that use the standard argument functions for that framework.
