[Q] What does this command actually do?

[das8nt]

Can someone help me by telling me what this command actually does?

echo 1 > /sys/devices/system/cpu/cpu1/online

A thread has been started elsewhere claiming this enables the "second core" for the Atrix CPU. I know there is no need to "enable." I just want to make sure applying this is not harmful as it's been instructed for people to do this on their phone and then use this to check and make sure it worked:

cat /proc/cpuinfo

Help would be appreciated as I want to avoid problems caused by misinformation.

Thanks in advance.

I don't know what these commands are supposed to be doing for you but...

"echo x > filename" is just going to create a file with x in it.

cat filename is just going to display what is in file.

Contact the original poster of that command and ask them for more info.

Thanks, I tried asking him. He essentially just found it somewhere on the net and decided to post it claiming that it 'cured' our 'inactive second core.' I don't think he knows, honestly. He's since stopped posting there. I just didn't want anyone to see it and try it and it do something harmful. Thanks again.
