-------------------------------------------
Summary: Executing multiple commands non-interactively with the C
client cli
Key: ZOOKEEPER-3646
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3646
Project: ZooKeeper
Issue Type: Improvement
Components: c client
Reporter: Mate Szalay-Beko
With the current C CLI client, we can execute a single command, using the
{{--cmd}} option.
However, when one wants to execute multiple commands in a session from a bash
script, he can not really do this now.
The idea is to allow to execute a command file, where ZooKeeper C client CLI
commands are specified in each line. It would be also great to support to read
the commands from the standard input, so one is able to use standard unix pipes
to channel commands to the zookeeper client. This would allow more dynamic
generation of commands from scripts.
What about the following syntax?
{code:bash}
# execute a single command (this is working now)
cli_mt --host localhost:2181 --cmd 'ls /zookeeper'
# new: execute a list of commands specified in a file
cli_mt --host localhost:2181 --cmd ./zk_commands.txt
# new: read the commands from stdin
cat ./zk_commands.txt | cli_mt --host localhost:2181 --cmd
{code}
Or if it is easier / nicer, we can add a new parameter and not use {{--cmd}}
for the last two cases.
Please assign the ticket to yourself if you start working on it (or leave a
comment).
