# NAME

`bpkg-pkg-update` – update package

# SYNOPSIS

`bpkg pkg-update|update [options] [vars] pkg...
bpkg pkg-update|update [options] [vars] --all|-a
bpkg pkg-update|update [options] [vars] (--all-pattern <pattern>)...`

# DESCRIPTION

The `pkg-update` command updates the specified packages (the first form), all the held packages (the second form, see `bpkg-pkg-status(1)`), or all the held packages that match any of the specified wildcard patterns (the third form). Additionally, immediate or all dependencies of these packages can be also updated by specifying the `--immediate|-i` or `--recursive|-r` options, respectively. Underneath, this command doesn't do much more than run `b update` (or one of its `update-for-*` variants; see `--for|-f`). In the first form the specified packages must have been previously configured with `bpkg-pkg-build(1)` or `bpkg-pkg-configure(1)`.

Additional command line variables (`vars`, normally `config.*`) can be passed to the build system. Such variables apply to all the specified packages but can also be specified to only apply to specific packages using the argument grouping mechanism (see `bpkg-argument-grouping(1)` for details).

# PKG-UPDATE OPTIONS

`--all`|`-a`
  Update all held packages.
`--all-pattern` `pattern`
  Update held packages that match the specified wildcard pattern. Repeat this option to match multiple patterns. Note that you may need to quote the pattern to prevent expansion by your shell.
`--immediate`|`-i`
  Also update immediate dependencies.
`--recursive`|`-r`
  Also update all dependencies, recursively.
`--for`|`-f` `operation`
  Instead of the default `update` build system operation, perform the `update-for-``operation` variant where `operation` is normally `install` or `test`.
`--directory`|`-d` `dir`
  Assume configuration is in `dir` rather than in the current working directory.
