Hyunsik Choi commented on TAJO-79:

The permission seems to not support general linux utils 'diff' and 'patch'. The permission
should be given when this patch is committed. Thanks!

> This patch improves TajoCli. This improvement is not backward compatible, but this improvement
makes TajoCli  more intuitive and similar to PostgreSQL cli. So, I believe this gives users
better experience. In addition, I've added some useful options.
> In detail, the patch does as follows:
>  * Refactor TajoCli to be based on command pattern
>  * multiple lines for one SQL statement are recorded as one history
>  * command prefix '/' is replaced by '\'.
>  * the command '/t' is replaced by '\d'.
>  ** '\d' lists tables or describes a table.
>  * jline version is updated to 2.11.
>  * add a help command '\?' to list all commands that can be used in TajoCli
>  * add a cli option '-c' for running a single SQL statement or command
>  * add a cli option '-f' for executing statements included in a text file
>  * add a script 'bin/tsql'
