Folder compression
Hi Guys,
totally new to scripting.

I have a huge list of foleders.
I want to tar the contents of each folder inside the same folder and the name of the tar file is the same name as the folder.

how would I go about this in scirpt?

cheers

Use of tar alone does not impart any compression, just as a heads-up. However, you can run any number of compression utils on the resulting .tar file(s).

How are you passing in your list of directories? A list file, or simply a search result?

I wanted to compress the content of each folder.
for example
for folder in folders
do
tar fxvc $folder
done

how to pass folders array to my script with each entry represneting a folder.

I hope I m not missing something here :-)

well, you're not missing anything per se...although you've got conflicting flags on the tar command, and then you need to pipe it into a known compression utility, such as gzip.

Assuming that you're only going to a specific level of the given directory structure (ie, you're not going to want to traverse below x number of directories from wherever you start, say 2 levels) you might try the following:

Code:
   #  to start off...find your files... 
find ./* -type d -maxdepth 2 
   #  then use this listing, as a variable, to run against...as you compress it altogether. 
     # tar cvpf will tar create-verbose-retain permission-using the file eventually named within the gzip call... 
tar cvpf - $(find ./* -type d -maxdepth 2 ) |gzip -9 - >tar_file.tgz 
   #  if you'd ever need to list it out...
gzip -cd tar_file.tgz |tar tvpf - 
   #  if you'd ever need to uncompress it (to extract and overlay the same files...)
gzip -cd tar_file.tgz |tar xvpf -
