NAME¶

kdb-get - Get the value of a key stored in the key database

SYNOPSIS¶

kdb get <key name>

Where key name is the name of the key.

DESCRIPTION¶

This command is used to retrieve the value of a key.

If you enter a key name starting with a leading /, then a cascading lookup will be performed in order to attempt to locate the key. In this case, using the -v option allows the user to see the full key name of the key if it is found.

Note: There is a current limitation where only keys that are mounted will be considered during a cascading lookup. A workaround that will lookup all keys is to pass the -a option. Additionally, a user can use the command kdb ls <same key> to see if an override or a fallback will be considered by the lookup.

OPTIONS¶

-H, --help

Show the man page.

-V, --version

Print version info.

-p, --profile <profile>

Use a different kdb profile.

-C, --color <when>

Print never/auto(default)/always colored output.

-a, --all

Consider all of the keys.

-n, --no-newline

Suppress the newline at the end of the output.

-v, --verbose

Explain what is happening. Gives a complete trace of all tried keys. Very useful to debug fallback and overrides.

EXAMPLES¶

To get the value of a key: kdb get user/example/key

To get the value of a key using a cascading lookup: kdb get /example/key

To get the value of a key without adding a newline to the end of it: kdb get -n /example/key

To explain why a specific key was used (for cascading keys): kdb get -v /example/key

To use bookmarks: kdb get +kdb/format

This command will actually get user/sw/elektra/kdb/#0/current/format if the bookmarks commands from kdb-set(1) kdb-set.md man pages are executed before.
