Example with pacman -Uh :
$ pacman -Uh
options:
  -b, --dbpath <path>  set an alternate database location
  -d, --nodeps         skip dependency checks
  -f, --force          force install, overwrite conflicting files
  -k, --dbonly         only modify database entries, not package files
  -r, --root <path>    set an alternate installation root
  -v, --verbose        be verbose
      --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
