flox rollback command¶
NAME¶
flox-rollback - rollback to a previous generation of an environment
SYNOPSIS¶
flox [ <general-options> ] rollback [ <rollback-options>]
DESCRIPTION¶
Managed environments evolve in atomic generations. Any change to a
managed environment is tracked as a new generation. By default,
flox activate will activate the latest generation.
flox rollback allows to reset the activated environment to an earlier
generation. When called without arguments, flox will reset the default
environment to the previous generation. A specific generation number
can be provided using the --to GENERATION option.
EXAMPLES¶
Changes to a managed environment are always made to the currently active environment:
$ flox create -e demo # Generation 1 ()
$ flox install -e demo hello # Generation 2 ( hello )
$ flox install -e demo vim # Generation 3 ( hello, vim )
$ flox rollback -e demo # Generation 2 ( hello )
$ flox install -e demo emacs # Generation 4 ( hello, emacs )
