Options:
|
||||||
|
|
||||||
|
-f|--file AUTHFILE : specify netrc-style files. Files with the .gpg extension
|
||||||
|
will be decrypted by GPG before parsing. Multiple -f
|
||||||
|
arguments are OK. They are processed in order, and the
|
||||||
|
first matching entry found is returned via the credential
|
||||||
|
helper protocol (see below).
|
||||||
|
|
||||||
|
When no -f option is given, .authinfo.gpg, .netrc.gpg,
|
||||||
|
.authinfo, and .netrc files in your home directory are used
|
||||||
|
in this order.
|
||||||
|
|
||||||
|
-k|--insecure : ignore bad file ownership or permissions
|
||||||
|
|
||||||
|
-d|--debug : turn on debugging (developer info)
|
||||||
|
|
||||||
|
-v|--verbose : be more verbose (show files and information found)
|
||||||
|
|
||||||
|
To enable this credential helper:
|
||||||
|
|
||||||
|
git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'
|
||||||
|
|
||||||
|
(Note that Git will prepend "git-credential-" to the helper name and look for it
|
||||||
|
in the path.)
|
||||||
|
|
||||||
|
...and if you want lots of debugging info:
|
||||||
|
|
||||||
|
git config credential.helper '$shortname -f AUTHFILE -d'
|
||||||
|
|
||||||
|
...or to see the files opened and data found:
|
||||||
|
|
||||||
|
git config credential.helper '$shortname -f AUTHFILE -v'
|
||||||
|
|
||||||
|
Only "get" mode is supported by this credential helper. It opens every AUTHFILE
|
||||||
|
and looks for the first entry that matches the requested search criteria:
|
||||||
|
|
||||||
|
'port|protocol':
|
||||||
|
The protocol that will be used (e.g., https). (protocol=X)
|
||||||
|
|
||||||
|
'machine|host':
|
||||||
|
The remote hostname for a network credential. (host=X)
|
||||||
|
|
||||||
|
'path':
|
||||||
|
The path with which the credential will be used. (path=X)
|
||||||
|
|
||||||
|
'login|user|username':
|
||||||
|
The credential’s username, if we already have one. (username=X)
|
||||||
|
|
||||||
|
Thus, when we get this query on STDIN:
|
||||||
|
|
||||||
|
host=github.com
|
||||||
|
protocol=https
|
||||||
|
username=tzz
|
||||||
|
|
||||||
|
this credential helper will look for the first entry in every AUTHFILE that
|
||||||
|
matches
|
||||||
|
|
||||||
|
machine github.com port https login tzz
|
||||||
|
|
||||||
|
OR
|
||||||
|
|
||||||
|
machine github.com protocol https login tzz
|
||||||
|
|
||||||
|
OR... etc. acceptable tokens as listed above. Any unknown tokens are
|
||||||
|
simply ignored.
|
||||||
|
|
||||||
|
Then, the helper will print out whatever tokens it got from the entry, including
|
||||||
|
"password" tokens, mapping back to Git's helper protocol; e.g. "port" is mapped
|
||||||
|
back to "protocol". Any redundant entry tokens (part of the original query) are
|
||||||
|
skipped.
|
||||||
|
|
||||||
|
Again, note that only the first matching entry from all the AUTHFILEs, processed
|
||||||
|
in the sequence given on the command line, is used.
|
||||||
|
|
||||||
|
Netrc/authinfo tokens can be quoted as 'STRING' or "STRING".
|
||||||
|
|
||||||
|
No caching is performed by this credential helper.
