In the first command, I am taking the files with name "abc_*.txt". Since i have used -t in the ls command, the file which is created recently will always come first. Then awk will pass the filenames other than the first record(this is the file we need to retain) to the xargs command to delete.
Second command is also quite similar. ls will take all the files starting with "abc_*.txt" and they are sorted by filename in descending order. The file with the latest timestamp will come first and the tail command will filter the first file(which is the latest) and pass the remaining filenames to the xargs to delete.
Hope my explanation is clear

git-pack-redundant
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.
