There are several methods of archiving files and retrieving archives in Unix-like systems like Linux. I personally use Ubuntu but you can apply these methods with all the Linux distros.
I recommend using the
zip function to compress your files for its ease of use and portability. (Files zipped in Linux can be extracted using various tools on various platforms including Windows).
Below I have provided various “unzip” methods. The “right” unzip method depends upon the method used to zip the file. You can tell the zip method by the file extension (e.g.,
Zipping Files Using ZIP
This Linux program is compatible with the zip program for Windows and most other operating systems. To zip files, first have the files uploaded to your server, then log into your account with SSH. Navigate to the directory where the files are that you want to zip (for instance by typing
cd www then
cd sounds to move to your
/www/sounds directory). Then type:
zip myzip file1 file2 file3
This puts the files named
file3 into a new zip archive called
Please note that the unzip method you use is defined by the filename you are trying to unzip. For example, if you are trying to unzip a file called
file.tar – you would use the method described in “tar“. Files ending in
.gz need to be extracted with the method described in “gunzip“.
If you have an archive named
myzip.zip and want to get back the files, you would type:
unzip by itself will give you a usage summary, showing nearly all the options available.
To extract a file compressed with tar (e.g.,
filename.tar), type the following command from your SSH prompt:
tar xvf filename.tar
Basically, this command means that you will see the file “explode”, so don’t worry when you see your screen scrolling wildly. It also means that you will see any errors in the archive.
To extract a file in Linux compressed with gunzip, type the following:
then if you receive no errors, type:
tar xvf filename_tar
