Check These Out
Really bored during class so I made this...
Basically, you hold period (or whatever) and hit enter after a second and you need to make the next line of periods the same length as the previous line...
My record was 5 lines of the same length.
It's best if you do it one handed with your pointer on period and ring on enter.
If two or more IPv6 addresses are assigned to an interface, apply this command to all but the address that you want to use as the source address of outbound packets.
This is Linux-specific and requires the iproute package, or equivalent for your distribution.
Returns your external IP address to the command line using only wget
If any changes have been made to the package while it was unpacked (ie, conffiles files in /etc modi‐fied), the new package will inherit the changes.
This way you can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer available elsewhere.
Note: dpkg-repack will place the created package in the current directory.
This will log your internet download speed.
You can run
$gnuplot -persist
If you're trying to create a sparse file, you can use dd by 'skip'ing to the last block instance.
ls -ls shows the actual size vs. the reported size
You can exclude more system folders or individual files which are not necessary for the backup and can be recreated after the restore procedure, like /lost+found, /mnt, /media, /tmp, /usr ...
Restoring the above backup procedure is as simple as becoming root and typing:
$ tar zxpf backup.tgz -C /
You can extract any file or directory out of the backup.tgz file for recovery, for instance, if you have a corrupt or mis-configured fstab file, you could simply issue the command:
$ tar zxpf backup.tgz /ect/fstab -C /
Other options:
v add verbose option to see files processed
A far safer solution is to restore the desired files under a different directory, and then compare, move, or update the files to their original locations afterward.
Locate config files of the program. May not be used for interactive programs like vim.
