Today's command parameters are relatively simple, so I want to learn more. The clear command is used to clear the screen. Ctrl + L has the same effect. The pwd (print working directory) command displays the current directory (absolute path ). The touch command is used to change the file time. You can use touch -- help to view the parameters. But it is generally used to create a file, that is, touch fileName. Of course, when the fileName file does not

Today, I encountered a grub repair problem again, and I have encountered it once before. I installed Ubuntu 10.04 and Windows 7. The default system startup Item is ubuntu.

Unfortunately, Windows cannot be started ~~ Grub won't be repaired, and it doesn't matter if you find something online .. At that t

When the hard disk is adjusted again, the Partition Number of the existing partition may change, or for some reason, changing the uuid of the startup partition will cause grub2 to fail to start normally, and starting to enter the repair mode (grub rescue) will fix grub. 1) Use the livecd disc of Versions later than ubuntu9.10 to start it.
