创建目录的tar.gz并清理除文件以外的目录？

Question

I would like to know if tar (1.15.1, Linux system) already has something like this before creating a script for it.

I would like to create a dir.tar.gz of a given dir/ that contains a specific dir/myfile.gz . I would like the command to do 2 specific things:

1. Preserve dir/myfile.gz
2. Delete everything else in dir/ after the dir.tar.gz is complete.

For example:

tree -if .
.
./dir
./dir/dir2
./dir/dir2/file3
./dir/file1
./dir/file2
./dir/myfile.gz

2 directories, 4 files

I would like the result of the tar command to be:

tree -if  
.
./dir
./dir/myfile.gz
./dir.tar.gz

1 directory, 2 files

I have read about the --delete and --extract options, but I am not sure how to apply them in one single command. Any ideas?

Answer 1

This should work:

tar -zcvf dir.tar.gz --exclude="*.gz" ./dir/. && find ./dir/. ! -name "*.gz" -exec rm -rf {} +

Test:

$ tree -if .
.
./dir
./dir/dir2
./dir/dir2/file3
./dir/file1
./dir/file2
./dir/myfile.gz

2 directories, 4 files

$ tar -zcvf dir.tar.gz --exclude="*.gz" ./dir/. && find ./dir/. ! -name "*.gz" -exec rm -rf {} +
./dir/./
./dir/./file1
./dir/./dir2/
./dir/./dir2/file3
./dir/./file2
rm: cannot remove `.' or `..'

$ tree -if .
.
./dir
./dir/myfile.gz
./dir.tar.gz

1 directory, 2 files
