inner for the session. The spinner is active when the terminal device is determined to be a TTY. This flag disables it regardless.

--oneshot (-1)

Emerge as normal, but do not add the packages to the world profile for later updating.

--onlydeps (-o)

Only merge (or pretend to merge) the dependencies of the packages specified, not the packages themselves.

--pretend (-p)

Instead of actually performing the merge, simply display what *would* have been installed if --pretend weren't used. Using --pretend is strongly recommended before installing an unfamiliar package. In the printout,

N = new, (not yet installed)
S = new, slot installation (side-by-side versions)
U = updating, (changing versions)
D = downgrade, (Best version seems lower)
R = replacing, (Remerging same version))
F = fetch restricted, (Manual download)
f = fetch restricted, (Already downloaded)
B = blocked by an already installed package

--quiet (-q)

Results may vary, but the general outcome is a reduced or condensed output from portage's displays.

--resume

Resumes the last merge operation. Please note that this operation will only return an error on failure. If there is nothing for portage to do, then portage will exit with a message and a success condition.

--searchdesc (-S)

Matches the search string against the description field as well as the package name. Take caution as the descriptions are also matched as regular expressions.

--skipfirst

This action is only valid when used with --resume. It removes the first package in the resume list so that a merge may continue in the presence of an uncorrectable or inconsequential error. This should only be used in cases where skipping the package will not result in failed dependencies.

--tree (-t)

Shows the dependency tree for the given target by indenting dependencies. This is only really useful in combination with --emptytree or --update and --deep.

--update (-u)

Updates packages to the best version available, which may not always be the highest version number due to masking for testing and development. This will also update direct dependencies which may not be what you want. In general, use this option only in combination with the world or system target.

--upgradeonly (-U)

Updates packages, but excludes updates that would result in a lower version of the package being installed. SLOTs are considered at a basic level.
