Compressing/Extracting files on your box

This wiki page is made for users who prefer not using Filebot which by default is turned on.

Extracting

---

• To extract files from a rar archive on the server, use this command:

unrar e SomeMovieChunkFile.rar

-e is for Extract files to current directory

• To list files inside rar archive without extracting them:

unrar l file.rar

-l is for list (not a number ‘one’)

• To extract files with full path, type this command:

unrar x file.rar

• To extract files with full path, and files are passworded, type this command:

unrar x -psomepassword file.rar

• To test integrity of archive file, type this command:

unrar t file.rar

-t is for testing integrity of archive

• To extract files from multiple subfolders ie. DVD1/somefile.rar DVD2/somefile2.rar, will extract to current folder

unrar x -r *.rar

Compressing

• To create a rar archive on the server:

rar a -R myarchive  ~/folder_to_archive

-a adds files to archive, ~/folder_to_archive is the directory we want commpressed into rar archive

• If you want to create a rar split archive:

 rar a -m5 -v5M -R myarchive ~/folder_to_archive

-m5 - determine the compression level (0-store (fast)...3-default...5-maximum(slow)) -v5M - determine the size of each file in split archive, in this example you get files with size 5MB (if you wanted files of 512kB size you would write -v512k)

• To split up a large file or folder and delete the original one, type this command:

rar a -v50m -df archive_name big_file_or_dir

-a is for Archive
-v50m -v is for Volume, 50m is 50 Megabytes this is the part size that the big file is split into.
-df is Delete and Force, this deletes the original file potentially saving you space.
archive_name is the part file name, e.g. big_movie.001.rar, ...002.rar, etc.
big_file_or_dir is the big file or folder you want to split up. e.g. big_movie.mkv or big_movie_plus_extras/
Finally, download the multiple archives via FTP much faster than a big file or folder ever could be.
