NAME

       opam-uninstall - An alias for remove.

SYNOPSIS

       opam uninstall [OPTION]... [PACKAGES]...

DESCRIPTION

       opam uninstall is an alias for opam remove.

       See opam remove --help for details.

ARGUMENTS

       PACKAGES
           List of package names, with an optional version or constraint, e.g `pkg', `pkg.1.0' or
           `pkg>=0.5'.

COMMON OPTIONS

       --color=WHEN (absent=auto)
           Colorize the output. WHEN must be one of `always', `never' or `auto'.

       --criteria=CRITERIA
           Specify user preferences for dependency solving for this run. Overrides both
           $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details on the supported language, and the
           external solvers available, see
           http://opam.ocaml.org/doc/Specifying_Solver_Preferences.html. A general guide to using
           solver preferences can be found at  http://www.dicosmo.org/Articles/usercriteria.pdf.
           The default value is
           -count(down),-count(removed),-notuptodate(solution),-sum(solution,version-lag),-count(new)
           for upgrades, and
           -count(removed),-notuptodate(request),-sum(request,version-lag),-count(down),-notuptodate(changed),-count(changed),-notuptodate(solution),-sum(solution,version-lag)
           otherwise.

       --cudf=FILENAME
           Debug option: Save the CUDF requests sent to the solver to FILENAME-<n>.cudf.

       --debug
           Print debug message to stderr. This is equivalent to setting $OPAMDEBUG to "true".

       --debug-level=LEVEL
           Like `--debug', but allows specifying the debug level (`--debug' sets it to 1).
           Equivalent to setting $OPAMDEBUG to a positive integer.

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

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

       --no-self-upgrade
           OPAM will replace itself with a newer binary found at OPAMROOT/opam if present. This
           disables this behaviour.

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

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

       --safe
           Make sure nothing will be automatically updated or rewritten. Useful for calling from
           completion scripts, for example. Will fail whenever such an operation is needed ; also
           avoids waiting for locks, skips interactive questions and overrides the OPAMDEBUG
           variable.

       --solver=CMD
           Specify the name of the external dependency solver. The default value is aspcud.
           Either 'aspcud', 'packup' or a custom command that may contain the variables
           %{input}%, %{output}% and %{criteria}%

       --strict
           Fail whenever an error is found in a package definition or a configuration file. The
           default is to continue silently if possible.

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

       --use-internal-solver, --no-aspcud
           Force use of internal heuristics, even if an external solver is available.

       -v, --verbose
           Be more verbose, show package sub-commands and their output. Repeat to see more.
           Repeating n times is equivalent to setting $OPAMVERBOSE to "n".

       -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 "true".

OPTIONS

       -a, --auto-remove
           Remove all the packages which have not been explicitly installed and which are not
           necessary anymore. It is possible to prevent the removal of an already-installed
           package by running opam install <pkg>. This flag can also be set using the
           $OPAMAUTOREMOVE configuration variable.

       -b, --keep-build-dir
           Keep the build directory. This is equivalent to setting $OPAMKEEPBUILDDIR to "true".

       -d, --build-doc
           Build the package documentation. This is equivalent to setting $OPAMBUILDDOC to
           "true".

       --dry-run
           Simulate the command, but don't actually perform any changes.

       -e TAGS, --external=TAGS
           Display the external packages associated to the given tags. This is deprecated, use
           `opam list --external' instead

       --fake
           This option registers the actions into the OPAM database, without actually performing
           them. WARNING: This option is dangerous and likely to break your OPAM environment. You
           probably want `--dry-run'. You've been warned.

       --force
           Execute the remove commands of given packages directly, even if they are not
           considered installed by OPAM.

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

       -j JOBS, --jobs=JOBS
           Set the maximal number of concurrent jobs to use. You can also set it using the
           $OPAMJOBS environment variable.

       --json=FILENAME
           Save the result output of an OPAM run in a computer-readable file

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

       --no-checksums
           Do not verify the checksum of downloaded archives.This is equivalent to setting
           $OPAMNOCHECKSUMS to "true".

       --require-checksums
           Reject the installation of packages that don't provide a checksum for the upstream
           archives. This is equivalent to setting $OPAMREQUIRECHECKSUMS to "true".

       --show-actions
           Call the solver and display the actions. Don't perform any changes.

       -t, --build-test
           Build and run the package unit-tests. This is equivalent to setting $OPAMBUILDTEST to
           "true".

       --version
           Show version information.
