I often force process to not display their output so that I can more easily run multiple of them in the background, for example:
youtube-dl -f 22 https://www.youtube.com/watch?v=oyg0xYH12Qg &>/dev/null &
without &>/dev/null they display information on the shell such as
[download] 69.5% of 1.34GiB at 360.36KiB/s ETA 19:53
What if I want to know those information with a command ?
I want to retrieve specific files then cp the result into another directory. It is all working, but my command seems to be executed a second time.
For example, I have a file a and I want to cp it into subdirectory test/, so I run:
find . -mtime -1 -name a -exec cp {} test/ ';'
My file is copied into the subdirectory as I wanted but then I get this error message:
cp: './test/a' and 'test/a' are the same file
Ubuntu is a mix open source source code like the linux kernel and other sources like the one from Canonical
My question is at which point can I see and compile its source code before being stuck on closed source code which will require me to trust blindly an entity
Lets say I want to install the gcc package using sudo apt-get install gcc but before I want to know the size of it, is there a command for that ?
Each time I want to use my usb external hard drive for the first time there is a short latency for allowing it to run, how to make it run at all time, so that while for example I watch a movie, stop and goes back to it it run instantly.
It would be best to have a script that stop it from shutting down for a certain period of time
