NAME¶
md_doc_help_kdb-sget - kdb-sget(1) -- Get the value of a key stored in the key database from a script kdb sget <key name> <default-value>
Where key name is the name of the key to retrieve and default-value is the value that should be printed if no value can be retrieved.
DESCRIPTION¶
This command is used to retrieve the value of a key from within a script. When using the kdb tool in a script, the user should use the sget command in place of the kdb-get(1) command. The kdb-get(1) command should not be used in scripts because it may return an error instead of printing a value in certain circumstances. The sget command guarantees that a value will be printed (unless the user passes faulty arguments). This command will either print the value of the key it retrieves or a default value that the user specifies.
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.
EXAMPLES¶
To get the value of a key from a script or return the value 0: kdb sget user/example/key 0
To get the value of a key using a cascading lookup or return the value notfound: kdb sget /example/key 'notfound'
