kdb-set(1) -- Set the value of a key

SYNOPSIS

kdb set <key name> [<value>]

Where key name is the name of the key you wish to set the value of (or create) and value is the value you would like to set the key to. If the value argument is not passed, the key will be set to a value of null.

DESCRIPTION

This command allows the user to set the value of an individual key.

EMPTY VALUES

To set a key to an empty value, "" should be passed for the value argument.

NEGATIVE VALUES

To set a key to a negative value, -- has to be used to stop option processing. (see example below)

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.
  • -v, --verbose: Explain what is happening.
  • -q, --quiet: Suppress non-error messages.
  • -N, --namespace=NS: Specify the namespace to use when writing cascading keys. See below in KDB.
  • --: Do not process any following arguments starting with - as options.

KDB

  • /sw/elektra/kdb/#0/current/verbose: Same as -v: Explain what is happening.

  • /sw/elektra/kdb/#0/current/quiet: Same as -q: Suppress default messages.

  • /sw/elektra/kdb/#0/current/namespace: Specifies which default namespace should be used when setting a cascading name. By default the namespace is user, except kdb is used as root, then system is the default.

EXAMPLES

To set a Key to the value Hello World!:
kdb set user/example/key "Hello World!"

To create a new key with a null value:
kdb set user/example/key

To set a key to an empty value:
kdb set user/example/key ""

To set a key to a negative value:
kdb set -- /tests/neg -3

To create bookmarks:
kdb set user/sw/elektra/kdb/#0/current/bookmarks

Followed by:
kdb set user/sw/elektra/kdb/#0/current/bookmarks/kdb user/sw/elektra/kdb/#0/current
