That's the problem: I know that instead of {} we could use any other symbol which would stand for the same thing. I know that xargs is essentially a loop that collects collects arguments and makes an utility execute it till the original input is exhausted. But what {} in the command line stands for actually? Is it empty space? If yes, is that the empty space that xargs is watching for in input? Or maybe it's a variable?

Also.

1. Could it be that in this case using xargs is equivalent to Find-And-Replace. Can we replace any word of the input to whatever comes to our mind


2.Does -R means a number of arguments replacement occurs in?

3. Can we replace any input with whatever we want with -I?

Could you please give an example of using xargs with both -I and -R options?

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.

SEE ALSO

       git-pack-objects(1) git-repack(1) git-prune-packed(1)
