Creating a .gz for a directory

[trs204]

Another newbie question...

I searched the internet couple of hours... I pity myself... for not being able to find a command for making .gz file for a directory.
I found only : gzip -c filename.txt
which creates a gz for a single file.. but I am in need of a command for a directory containing files/directories.

please advise. thx in advance.

Gzip, by design, is used to compress single files. The traditional method for creatinga compressed directory, is by using the TAR utility, with compression enabled:

# tar -czvf directory.tar.gz directory/

my requirement says... somebody going to provide me gz and tar.gz both types containing multiple files...

To uncompress... I found the commands:
1) gunzip file.gz ( not sure how to make a sample to test this)
2) tar zxvf file.tar.gz ( able to test this by creating a tar and compressing it)

but as you mentioned... as per the design only file can be compressed... nto the directory... do you mean that they cant the provide me a .gz file, which contains multiple normal files/directories.

thx in advance.

theoretically speaking, it can be done without using tar. say you have 2 files, file1 and file2 you need to compress together

cat file1 file2  | gzip > together.gz # compress 2 files into single
gunzip -c together.gz  # this is same as cat file1 file2

but i think tar is still better.

Thanks for the reply.. I was able to create the .gz file by specifying multiple files... but when I decompress it using this....
gunzip filename.gz ==> this gave only one file.

I think... cat does the concatenation of multiple files into a single file...

But my situation... is... I am in need of a command that can zip a directory... that directory contains some directories and some files.... and want to retain the same directory structure when I am decompress it.

Looks like they cannot provide me .gz file, which has multiple files and directories. .... is that my understanding seems right?

Thx in advance.

Not without using another utility such as tar.

Thanks Motoma. And thank you all for making me comfortable on this.

You are welcome. Glad to help.
