  • The files are automatically uncompressed when they reach the destination machine. This is a fast way to backup your server to your local computer while it's running (shutting down services is recommended). A file named "exclude.txt" is needed at /tmp/ containing the following : /dev/* /media/* /mnt/* /proc/* /sys/* /tmp/* /home/*/.local/share/Trash /home/*/.gvfs /home/*/.cache /home/*/.thumbnails /etc/fstab /lib/modules/*/volatile/.mounted /var/run/* /var/lock/* /var/tmp/* /var/cache/apt/archives/* /lost+found/* Show Sample Output

  • In order to create a new encrypted filing system managed by cryptmount, you can use the supplied 'cryptmount-setup' program, which can be used by the superuser to interactively configure a basic setup. Alternatively, suppose that we wish to setup a new encrypted filing system, that will have a target-name of "opaque". If we have a free disk partition available, say /dev/hdb63, then we can use this directly to store the encrypted filing system. Alternatively, if we want to store the encrypted filing system within an ordinary file, we need to create space using a recipe such as: dd if=/dev/zero of=/home/opaque.fs bs=1M count=512 . cryptmount --generate-key 32 opaque . cryptmount --prepare opaque . mke2fs /dev/mapper/opaque . cryptmount --release opaque . mkdir /home/crypt . cryptmount -m opaque . cryptmount -u opaque For detail see sample output Show Sample Output

  • cd into the directory that contains the file. this is just the usual move command but shortcut'd. say you wanted to move a photo img1.png from ~/photos/holidayphotos into the parent directory which is ~/photos command would be: ~/photos/holidayphotos$ mv img1.png .. I use Ubuntu so this'll work in debian but not sure what else.

    mv file_name.extension ..

Split huge file into DVD+R size chunks for burning
Real DVD+R size is 4700372992 bytes, but I round down a little to be safe. To reconstitute use cat. "cat file.img.gz.aa file.img.gz.ab ..... > file.img.gz"

Find the package that installed a command

Delete all but the latest 5 files, ignoring directories

cat stdout of multiple commands
Concatenate the stdout of multiple commands.

Generates a TV noise alike output in the terminal
Generates a TV noise alike output in the terminal. Can be combined with https://www.commandlinefu.com/commands/view/9728/make-some-powerful-pink-noise

check open ports without netstat or lsof

Check command history, but avoid running it
!whatever will search your command history and execute the first command that matches 'whatever'. If you don't feel safe doing this put :p on the end to print without executing. Recommended when running as superuser.

Convert file type to unix utf-8
converts encoding of a file to unix utf-8 useful for data files that contain what would be usable ascii text but are encoded as mpeg or some other encoding that prevents you from doing common manipulations like 'sed'

most used commands in history (comprehensive)
Most of the "most used commands" approaches does not consider pipes and other complexities. This approach considers pipes, process substitution by backticks or $() and multiple commands separated by ; Perl regular expression breaks up each line using | or < ( or ; or ` or $( and picks the first word (excluding "do" in case of for loops) note: if you are using lots of perl one-liners, the perl commands will be counted as well in this approach, since semicolon is used as a separator

check open ports without netstat or lsof
