Maybe it's an stupid question but remeber... I'm Junior.. I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"...

GIT-PRUNE(1)							    Git Manual							      GIT-PRUNE(1)

NAME

       git-prune - Prune all unreachable objects from the object database

SYNOPSIS

       git prune [-n] [-v] [--progress] [--expire <time>] [--] [<head>...]

DESCRIPTION

	   Note
	   In most cases, users should run git gc, which calls git prune. See the section "NOTES", below.

       This runs git fsck --unreachable using all the refs available in refs/, optionally with additional set of objects specified on the command
       line, and prunes all unpacked objects unreachable from any of these head objects from the object database. In addition, it prunes the
       unpacked objects that are also found in packs by running git prune-packed. It also removes entries from .git/shallow that are not reachable
       by any ref.

       Note that unreachable, packed objects will remain. If this is not desired, see git-repack(1).

OPTIONS

       -n, --dry-run
	   Do not remove anything; just report what it would remove.

       -v, --verbose
	   Report all removed objects.

       --progress
	   Show progress.

       --expire <time>
	   Only expire loose objects older than <time>.

       --
	   Do not interpret any more arguments as options.

       <head>...
	   In addition to objects reachable from any of our references, keep objects reachable from listed <head>s.

EXAMPLE

       To prune objects not used by your repository or another that borrows from your repository via its .git/objects/info/alternates:

	   $ git prune $(cd ../another && git rev-parse --all)

NOTES

       In most cases, users will not need to call git prune directly, but should instead call git gc, which handles pruning along with many other
       housekeeping tasks.

       For a description of which objects are considered for pruning, see git fsck's --unreachable option.
