Reverse exclude for Tar

[blocked]

Basically instead of excluding files for tar, I want to include the files i wanna compress.

[mariushm]

most compression programs allow you to specify a list of files you want to include

So you can make your list of files with just the extensions you want , or the file names you want, or whatever other filtering you think of (size under x bytes, last modified n days ago etc) , dump it to a text file and then give your tar program the file list as parameter ... something like 

7zip a -ttar archive.tar @c:\filelist.txt

 

7zip also has command line parameters to exclude stuff 

 

-x[r[-|0]]{@listfile|!wildcard} : eXclude filenames

 

Quote

7z a -tzip archive.zip *.txt -x!temp.*

adds to the archive.zip all *.txt files, except temp.* files.

7z a archive.7z Folder1\ -xr!*.png

adds to the archive.7z all files from Folder1 and its subfolders, except *.png files.
