Sqoop not working at all

I am trying to execute sqoop commands.Nothing working

[sukhjinder@gw03 ~]$ sqoop list-tables\

–connect jdbc:mysql://ms.itversity.com:3306/retail_db
–username retail_user
–password itversity
No such sqoop tool: list-tables–connect. See ‘sqoop help’.

You are not following sqoop syntax correctly, please refer this link. And also you have to give \ at the end of each line except the last one to write a long command in multiple lines.
Please refer the command below

sqoop list-tables \
  --connect jdbc:mysql://ms.itversity.com:3306/retail_db \
  --username retail_user \
  --password itversity
