Perhaps something like this might do it:-
The problem you are seeing is because tar is seeing the input as -f [I]first_file_listed item1_to_extract item2_to_extract so you might get away with adding -n 1 to xargs like this:-
This will at least run tar for each file separately. I'm not sure how it will handle the pipe to grep, but it should work.
I hope that these help. If not, please run it with debug on your shell (i.e. set -x first) and paste the output in CODE tags. It would help if you have a small set of small (few members) tar files to keep the output manageable.
I have a SQL script that requires values from the environment in order to execute. I found a way to get the desired results but my process is a little choppy. Any suggestions on how to clean this up would be greatly appreciated.

This is going to be part of a longer script with more features, but I have boiled it down to the one thing that is presently stumping me. The goal is a script which checks for updates to web pages that can be run as a cron job. The script reads (from a tab-delim file) a URL, an MD5 digest, and an... (1 Reply)

Using the below code I want to find all .sff files and extract them. This works but it seems very cheap. Is there a safer more efficient way to go about this?

GIT-PACK-REDUNDANT(1) Git Manual GIT-PACK-REDUNDANT(1)NAME
git-pack-redundant - Find redundant pack files
SYNOPSIS
git pack-redundant [ --verbose ] [ --alt-odb ] < --all | .pack filename ... >
DESCRIPTION
This program computes which packs in your repository are redundant. The output is suitable for piping to xargs rm if you are in the root of
the repository.
git pack-redundant accepts a list of objects on standard input. Any objects given will be ignored when checking which packs are required.
This makes the following command useful when wanting to remove packs which contain unreachable objects.
git fsck --full --unreachable | cut -d ' ' -f3 | git pack-redundant --all | xargs rm
OPTIONS --all
Processes all packs. Any filenames on the command line are ignored.
--alt-odb
Don't require objects present in packs from alternate object directories to be present in local packs.
--verbose
Outputs some statistics to stderr. Has a small performance penalty.
