kdb-get(1) – 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.

LIMITATIONS

Only keys within the mount point or below the <key name> will be considered during a cascading lookup. A workaround is to pass the -a option. Use the command kdb get -v <key name> to see if an override or a fallback was considered by the lookup.

RETURN VALUES

This command will return the following values as an exit status:

  • 0: No errors.
  • 1-10: standard exit codes, see kdb(1)
  • 11: No key found.

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) man pages are executed before.
