NAME

       opam-remove - Remove a list of packages.

SYNOPSIS

       opam remove [OPTION]... [PACKAGES]...

DESCRIPTION

       This command removes (i.e. uninstalls) one or more packages currently installed in the
       currently selected compiler switch. To remove packages installed in another compiler, you
       need to switch compilers using opam switch or use the --switch flag. This command is the
       inverse of opam-install.

ARGUMENTS

       PACKAGES
           List of package names.

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

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

       -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 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.

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

       --compat-mode-1.0
           Compatibility mode with OPAM 1.0

       --debug
           Print debug message on stdout. This is equivalent to setting $OPAMDEBUG to a non-empty
           value.

       --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-aspcud
           Do not use the external aspcud solver, even if available.

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

       --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.

       -v, --verbose
           Be more verbose. This is equivalent to setting $OPAMVERBOSE to a non-empty value.

       --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.

ENVIRONMENT VARIABLES

       opam makes use of environment variables listed here.

       OPAMCOLOR, when set to always or never, sets a default value for the --color option

       OPAMCURL can be used to define an alternative for the 'curl' command-line utility to
       download files
