bpkg-cfg-link(1)

NAME
bpkg-cfg-link - link configuration

SYNOPSIS

bpkg cfg-link [options] dir

DESCRIPTION

The cfg-link command links the specified bpkg configuration with the current configuration. Note that it also establishes an implicit backlink from the specified to the current configuration. See bpkg-cfg-create(1) for background on linked configurations. To unlink previously linked configurations use bpkg-cfg-unlink(1).

The linked configurations are normally referred to using names when specified on the bpkg command line. Unless overridden with the --name option, the original configuration name is used to name the link. If the link is unnamed, then it can be referred to using the numeric id that is automatically assigned when establishing the link or using the configuration UUID.

If the specified configuration path is relative, then it is rebased relative to the current configuration directory. This way, when the linked configurations are moved around together, the stored relative paths remain valid. If the specified directory path is absolute, then it is stored as absolute unless the --relative option is specified in which case it is also rebased relative to the current configuration directory.

CFG-LINK OPTIONS

--name name
    Alternative link name. If this option is not specified, then the configuration name is used as the link name (see bpkg-cfg-create(1) for details).

--relative
    Rebase the absolute linked configuration path relative to the current configuration directory.

--directory|-d dir
    Assume configuration is in dir rather than in the current working directory.
