I want to create a tarball of files, but not include the directory name. I know there's another way to do it, but I want to know why this way is not working.

If I run the following to create the tarball comprised of a specific file, then it works:

tar -vcf file.tar -C <PATH TO DIR> file1

However, if I run it on a wild card to include multiple files, then it fails:

tar -vcf file.tar -C <PATH TO DIR> *

I get an error saying, for each file in the current dir (not the dir specified in -C), tar: <FILE>: Cannot stat: No such file or directory

Any idea why running the above command on a wild card vs a file name behaves differently?

回答1:

The * wildcard is expanded by the shell before tar is invoked. tar then changes directory (because you asked it to), but then can't find the files that were in the shell's current directory.

Of course, changing directories in the shell means that you can't open the output file in the original current directory. So you have to redirect the output of tar outside of the subshell, like this:

(cd $DIR; tar -vc *) > file.tar

回答2:

You have to use a directory:

tar -vcf files.tar /path/to/directory

If your files are in your folder, then use the . to reference the current folder:

tar -vcf files.tar .
