Simple Interactive Wrapper of CLI with sub-command with Go

Nowdays, we have lots of CLI tools with many sub-commands, eg. hdfs, etcdctl... When we use these tools continuously， we may input main-command again by again.

This little wrapper will help you to reduce that useless input.

Usage

hdfs is the CLI.

# install test cli(hdfs), just for example
go get github.com/colinmarc/hdfs/cmd/hdfs
# config to connect to your hadoop
export HADOOP_NAMENODE="wxnn:8020"

go build -o interactive
./interactive hdfs

!quit will quit the current interactive session

!cmd will execute cmd in shell, eg. !ls will list files.
cmd will execute cmd will the main-cmd, eg. ls / will run hdfs ls / and list files in the hdfs.

./interactive hdfs
> ls -l /
drwxr-xr-x hbase       hbase  0 Feb 23 14:15 hbase
drwxrwxrwx  hdfs  supergroup  0 Feb 23 14:23 tmp
drwxrwxrwx  hive        hive  0 Feb 23 17:00 user
