How to untar all .tar.gz with shell-script?

Question

I tried this:

DIR=/path/tar/*.gz

if [ "$(ls -A $DIR 2> /dev/null)" == "" ]; then
  echo "not gz"
else
  tar -zxvf /path/tar/*.gz -C /path/tar
fi

If the folder has one tar, it works. If the folder has many tar, I get an error.

How can I do this?

I have an idea to run a loop to untar, but I don't know how to solve this problem

Answer 1

The accepted answer worked for me with a slight modification

for f in *.tar.gz
do
  tar zxvf "$f" -C \name_of_destination_folder_inside_current_path
done

I had to change the forward slash to a backslash and then it worked for me.

Answer 2

for a in /path/tar/*.gz
do
    tar -xzvf "$a" -C /path/tar
done

Notes

• This presumes that files ending in .gz are gzipped tar files. Usually .tgz or .tar.gz is used to signify this, however tar will fail if something is not right.
• You may find it easier to cd /path/tar first, then you can drop the -C /path/tar from the untar command, and the /path/tar/ in the loop.

Answer 3

for f in *.tar.gz
do
  tar zxvf "$f" -C /path/tar
done

Answer 4

I find the find exec syntax very useful:

find . -name '*.tar.gz' -exec tar -xzvf {} \;

{} gets replaced with each file found and the line is executed.
