A common one is word changing this command for shutdown
sudo shutdown -r now
To this one
Sudo shutdown –r now
Both look the same but the second on will not work.
A capital S has been added to sudo which won’t be recognised, and also the -r has been changed to –r, which will not be recognised either.
So if a command does not work using copy and paste simply type the command manually to fix this problem.
Actual code snippets inside phpbb code boxes like this one are not normally affected by this problem.
