Sometimes I need to run dolphin in console to see the current directory in a GUI (because of some features I've implemented over it).
So I try to do (dolphin > /dev/null) & in order not to have many output but I get messages like QPixmap::scaled: Pixmap is a null pixmap in the console even doing > /dev/null
So what's the problem with my command in order not to show output ?
I've got a huge directory on my computer and I need to search in every ruby file inside for a string.
I could have done it like this : grep -R "string" *.rb but it takes really long and I'd like to use pv (pipe viewer) to show a progress bar to be able to monitor grep progress.
But I don't really know how can I write this command because there are still some things I just can't understand about this command.
Has someone got any idea ?
