Unable to execute multiple commands from Linux terminal [Red-Hat, Centos, Unix, too]?

I want to execute multiple commands from Linux terminal on Linux Red-hat.

 echo deltaasm |. oraenv && snrctl status;

[oracle@DeltaLinOraASM2 datavail]$  echo deltaasm |. oraenv && snrctl status;
ORACLE_SID = [oracle] ? The Oracle base has been set to /u01/app/oracle
bash: snrctl: command not found

If execute the same command on Linux ubuntu it works perfectly. I am unable to execute on Linux Red Hat. . oraenv script sets oracle home and sid of oracle so oracle related commands will work. But if i execute from terminal it works ok here is the result

[oracle@DeltaLinOraASM2 datavail]$ . oraenv
ORACLE_SID = [oracle] ? deltaasm
The Oracle base has been set to /u01/app/oracle
[oracle@DeltaLinOraASM2 datavail]$ lsnrctl status

Please suggest on the above problem, thank you

The problem is that I can execute on this Linux Ubuntu, with any trouble but I am facing problem to execute on Linux Centos And some of the other flavors of Linux distro. Tried on Ubuntu, Not working on Red-Hat, Centos, Unix, too. Thank You for your suggestion.
