Checking contents of TAR file

[Pando]

Dear Gurus,

I have a tar files when checked using -t option have no files in it. Is there a test to check if the tar file contains files or no files at all?

Hello All,

What i am looking for is to test the tar file if it contains files. Actually am creating a script for checking if the existing tar files contains file in it, if it contains no file at all, it will be discarded or remove from my system.

You can try as,

tar -tvf PPS1XX15_20051013-144204.tar > /tmp/tartest.log

if [ ! -s /tmp/tartest.log ]
then
rm -f PPS1XX15_20051013-144204.tar /tmp/tartest.log
fi

hth.

# perl -MArchive::Tar -e'for(@ARGV){Archive::Tar->list_archive($_)or unlink$_}' *.tar

Throws away empty tar files

Hi,

You can use the strings command also.

#!/sbin/sh
if [ `strings test.tar| grep ustar| wc -l` -le 1 -a `tar -tvf test.tar| egrep ".*/$"| wc -l` -eq `strings test.tar| grep ustar| wc -l` ]
then
echo "The tar file test.tar contains no files"
else
echo "The tar file test.tar contains some files"
fi


Thanks.
