The command echo "${url=http:--example-com}" | git credential reject
is used to reject or invalidate a stored credential entry for a specific URL in Git.
Here's a breakdown of what each part of the command does:
-
echo
: This is a command in Unix-like operating systems that prints the given arguments to the terminal or standard output. -
"${url=http:--example-com}"
: This sets the environment variable$url
to the valuehttp:--example-com
. The format${variable=value}
is used to assign a default value to a variable if it is not already set. In this case, if the$url
variable is not set, it will be assigned the valuehttp:--example-com
. The variable$url
typically represents the URL that needs to be rejected. -
|
: This is a pipe operator that connects the output of theecho
command to the input of thegit credential reject
command. It allows the output of one command to be used as input for another command. -
git credential reject
: This is a Git command that rejects a stored credential entry for a given URL. It communicates with the Git credential system, which can store and retrieve credentials (such as usernames and passwords) for different remote repositories.
In summary, this command combines setting a default URL value using echo
and rejecting that URL's stored credential entry using git credential reject
. It is typically used to discard or invalidate a stored credential for a specific URL in Git.
