Usage: vault write [options] path [data]
Write data (secrets or configuration) into Vault.
Write sends data into Vault at the given path. The behavior of the write
is determined by the backend at the given path. For example, writing
to "aws/policy/ops" will create an "ops" IAM policy for the AWS backend
(configuration), but writing to "consul/foo" will write a value directly
into Consul at that key. Check the documentation of the logical backend
you're using for more information on key structure.
Data is sent via additional arguments in "key=value" pairs. If value
begins with an "@", then it is loaded from a file. If you want to start
the value with a literal "@", then prefix the "@" with a slash: "\@".
General Options:
` + generalOptionsUsage() + `
Write Options:
-f | -force Force the write to continue without any data values
specified. This allows writing to keys that do not
need or expect any fields to be specified.
