kdb-cp(1) -- Copy keys within the key database

kdb cp <source> <dest>

This command copies key(s) in the Key database. You can copy keys to another directory within the database or even below another key. Note that you cannot copy a key below itself.

Where source is the path of the key(s) you want to copy and dest is the path where you would like to copy the key(s) to. Note that when using the -r flag, source as well as all of the keys below it will be copied.

Neither source nor dest can be a cascading key. (Start with /). Make sure to select a namespace.

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

# Backup-and-Restore: user:/tests/cp/examples
# Create the keys we use for the examples
kdb set user:/tests/cp/examples/kdb-cp/key key1
kdb set user:/tests/cp/examples/kdb-cp/key/first key
kdb set user:/tests/cp/examples/kdb-cp/key/second key
kdb set user:/tests/cp/examples/kdb-cp/cpkey key1
kdb set user:/tests/cp/examples/kdb-cp/cpkey/first key
kdb set user:/tests/cp/examples/kdb-cp/cpkey/second key
kdb set user:/tests/cp/examples/kdb-cp/cpkeyerror/first key
kdb set user:/tests/cp/examples/kdb-cp/cpkeyerror/second anotherValue
kdb set user:/tests/cp/examples/kdb-cp/another/key one
kdb set user:/tests/cp/examples/kdb-cp/another/value two
# To copy a single key:
kdb cp user:/tests/cp/examples/kdb-cp/key user:/tests/cp/examples/kdb-cp/key2
#>
# To copy multiple keys:
kdb cp -r user:/tests/cp/examples/kdb-cp/key user:/tests/cp/examples/kdb-cp/copied
#>
# If the target-key already exists and has a different value, cp fails:
kdb cp -r user:/tests/cp/examples/kdb-cp/key user:/tests/cp/examples/kdb-cp/cpkeyerror
# RET: 11
# If the target-key already exists and has the same value as the source, everything is fine:
kdb cp -r user:/tests/cp/examples/kdb-cp/key user:/tests/cp/examples/kdb-cp/cpkey
#>
# To force the copy of keys:
kdb cp -rf user:/tests/cp/examples/kdb-cp/key user:/tests/cp/examples/kdb-cp/cpkeyerror
#>
# Now the key-values of /cpkeyerror are overwritten:
kdb export user:/tests/cp/examples/kdb-cp/cpkeyerror mini
#> =key1
#> first=key
#> second=key
# To copy keys below an existing key:
kdb cp -r user:/tests/cp/examples/kdb-cp/another user:/tests/cp/examples/kdb-cp/another/key
#>
kdb rm -r user:/tests/cp/examples/kdb-cp/
