This command will copy a folder tree (keeping the parent folders) through ssh. It will:
- compress the data
- stream the compressed data through ssh
- decompress the data on the local folder
This command will take no additional space on the host machine (no need to create compressed tar files, transfer it and then delete it on the host).
There is some situations (like mirroring a remote machine) where you simply cant wait for a huge time taking scp command or cant compress the data to a tarball on the host because of file system space limitation, so this command can do the job quite well.
This command performs very well mainly when a lot of data is involved in the process. If you copying a low amount of data, use scp instead (easier to type)
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
This will generate the same output without changing the current directory, and filepath will be relative to the current directory.
Note: it will (still) fail if your iTunes library is in a non-standard location.
This assumes you have the 'rpm', 'rpm2cpio' and 'cpio' packages installed. This will extract the contents of the RPM package to your current directory. This is useful for working with the files that the package provides without installing the package on your system. Might be useful to create a temporary directory to hold the packages before running the extraction:
$ mkdir /tmp/new-package/; cd /tmp/new-package
Usage: say hello world how are you today
This command is useful when you want to know what process is responsible for a certain GUI application and what command you need to issue to launch it in terminal.
