Using c shell
 

Hi all,
Am very new to linux, I have been restricted to use c shell to configure my redhat box to work with oracle on our test system

I noticed that am using bourne shell, how do i convert my system so that i use c shell so that i set environment variables for oracle
setenv ORACLE_SID testdb
setenv ORACLE_HOME /u01/oracle/oratest/bin
e.t.c

You can try the chsh command:
You will be prompted for your password, then you can verify the shell effectively changed by looking at your user entry in /etc/passwd. If it does not work (that is you don't have permissions to run the chsh command) the only option is asking to the system administrator.
