nix-env [OPTIONS...] [ARGUMENTS...]
`nix-env' is a tool to manipulate Nix user environments.
Operations:
* Implemented Eelco V.'s `nix-env -I' command to specify the default path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2004-01-05 16:26:43 +00:00
--install / -i: add derivations to the user environment
--upgrade / -u: upgrade derivation in the user environment
* Version numbers can be omitted in install/uninstall. E.g., nix-env -i foo.nix subversion The version number part of a derivation name is defined as everything following the first dash not followed by a letter.
2003-12-21 23:58:56 +00:00
--uninstall / -e: remove derivations from the user environment
* Help text for all (non-script) programs, so no more: $ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)

--query / -q: perform a query on an environment or Nix expression
The previous operations take a list of derivation names. The special
name `*' may be used to indicate all derivations.
* Implemented Eelco V.'s `nix-env -I' command to specify the default path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2004-01-05 16:26:43 +00:00
--profile / -p [FILE]: switch to specified user environment
--import / -I FILE: set default Nix expression
* Implemented Eelco V.'s `-p' command to switch profiles. It switches the symlink ~/.nix-userenv to the given argument (which defaults to .../links/current). /etc/profile.d/nix-profile creates this symlink if it doesn't exist yet. Example use: $ nix-env -l my_profile -i foo.nix subversion quake $ nix-env -p my_profile I don't like the term "profile". Let's deprecate it :-)

2003-12-01 15:55:05 +00:00
--version: output version information
--help: display help
Query types:
--name: print derivation names (default)
* Sort `nix-env -q' output by derivation name. * `--version' flag for all commands. * Manual updates.
2004-02-02 10:51:54 +00:00
--expr: print derivation store expression
* Help text for all (non-script) programs, so no more: $ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
2003-12-01 15:55:05 +00:00
--status / -s: print installed/present status
Query sources:
--installed: use installed derivations (default)
* Implemented Eelco V.'s `nix-env -I' command to specify the default path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2004-01-05 16:26:43 +00:00
--available / -a: use derivations available in Nix expression
* Help text for all (non-script) programs, so no more: $ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
2003-12-01 15:55:05 +00:00
Options:
* `-u' -> `-e'. * `--link' / `-l' flag to specify the switch symlink to use (by default, /nix/var/nix/links/current).
2003-12-21 22:34:41 +00:00
--link / -l LINK: use symlink LINK instead of (...)/current
* Implemented Eelco V.'s `nix-env -I' command to specify the default path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2004-01-05 16:26:43 +00:00
--file / -f FILE: use Nix expression FILE for installation, etc.
* Help text for all (non-script) programs, so no more: $ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
2003-12-01 15:55:05 +00:00
--verbose / -v: verbose operation (may be repeated)
--keep-failed / -K: keep temporary directories of failed builds
