Example with pacman -Uh :
options:
--arch <arch> set an alternate architecture
--asdeps install packages as non-explicitly installed
--asexplicit install packages as explicitly installed
--cachedir <dir> set an alternate package cache location
--config <path> set an alternate configuration file
--debug display debug messages
--ignore <pkg> ignore a package upgrade (can be used more than once)
--ignoregroup <grp>
ignore a group upgrade (can be used more than once)
--logfile <path> set an alternate log file
--noconfirm do not ask for any confirmation
--noprogressbar do not show a progress bar when downloading files
--noscriptlet do not execute the install scriptlet if one exists
--print only print the targets instead of performing the operation
--print-format <string>
specify how the targets should be printed
-b, --dbpath <path> set an alternate database location
-d, --nodeps skip dependency checks
-f, --force force install, overwrite conflicting files
-k, --dbonly add database entries, do not install or keep existing files
-r, --root <path> set an alternate installation root
-v, --verbose be verbose
