OPAM-UPGRADE(1)

NAME

opam-upgrade - Upgrade the installed package to latest version.

SYNOPSIS

opam upgrade [OPTION]... [PACKAGES]...

DESCRIPTION

This command upgrades the installed packages to their latest available versions. More precisely, this command calls the dependency solver to find a consistent state where most of the installed packages are upgraded to their latest versions.

ARGUMENTS

PACKAGES
    List of package names.

OPTIONS

-b, --keep-build-dir
    Keep the build directory. This is equivalent to setting $OPAMKEEPBUILDIR to a non-empty string.

--cudf=FILENAME
    Save the CUDF request sent to the solver to FILENAME-<n>.cudf.

-d, --build-doc
    Build the package documentation. This is equivalent to setting $OPAMBUILDDOC to a non-empty string.

--dry-run
    Simply call the solver without actually performing any build/install operations.

-e TAGS, --external=TAGS
    Display the external packages associated to the given tags.

--fake
    WARNING: This option is fo testing purposes only! Using this option without care is the best way to corrupt your current compiler environement. When using this option OPAM will run a dry-run of the solver and then fake the build and install commands

-m MAKE, --make=MAKE
    Use MAKE as the default 'make' command.

-n, --no-checksums
    Do not verify the checksum of downloaded archives.This is equivalent to setting $OPAMNOCHECKSUMS to a non-empty string.

-t, --build-test
    Build and run the package unit-tests. This is equivalent to setting $OPAMBUILDTEST to a non-empty string.

COMMON OPTIONS

These options are common to all commands.

--debug
    Print debug message on stdout. This is equivalent to setting $OPAMDEBUG to a value greater or equal to 2.

--git-version
    Print the git version if it exists and exit.

--help[=FMT] (default=pager)
    Show this help in format FMT (pager, plain or groff).

--no-base-packages
    Do not install base packages (useful for testing purposes). This is equivalent to setting $OPAMNOBASEPACKAGES to a non-empty string.

-q, --quiet
    Be quiet when installing a new compiler.

-r ROOT, --root=ROOT (absent=/Users/tgazagna/.opam)
    Use ROOT as the current root path. This is equivalent to setting $OPAMROOT to ROOT.

--switch=SWITCH
    Use SWITCH as the current compiler switch. This is equivalent to setting $OPAMSWITCH to SWITCH.

-v, --verbose
    Be more verbose. This is equivalent to setting either $OPAMDEBUG to a value greater or equal to 1 or $OPAMVERBOSE to a non-empty string.

--version
    Show version information.

-y, --yes
    Disable interactive mode and answer yes to all questions that would otherwise be asked to the user. This is equivalent to setting $OPAMYES to a non-empty string.
