|
|
|
Operations:
|
|
|
|
--install / -i: add derivations to the user environment
|
|
--upgrade / -u: upgrade derivation in the user environment
|
|
--set: create a user environment containing a single derivation
|
|
--uninstall / -e: remove derivations from the user environment
|
|
--query / -q: perform a query on an environment or Nix expression
|
|
--set-flag NAME VALUE: set derivation meta-attribute to given value
|
|
|
|
The previous operations take a list of derivation names. The special
|
|
name `*' may be used to indicate all derivations.
|
|
|
|
--switch-profile / -S [FILE]: switch to specified profile
|
|
--switch-generation / -G NUMBER: switch to specified generation of profile
|
|
--rollback: switch to the previous generation
|
|
--list-generations: list available generations of a profile
|
|

|
|
`old' for all non-current generations

|
|
--no-name: hide derivation names
|
|

|
|
derivation which can be used when installing with -A
|
|
--system: print the platform type of the derivation
|

|
|
--drv-path: print path of derivation
|
|
--out-path: print path of derivation output
|
