If i type $ export $SHELL --this will give the current shell. But if i change the shell to ksh, $ ksh --this wont be reflected in the Shell variable (SHELL). So if this is the case how to know in which shell i am present ! regs

The prompt will tell u. but same prompt for ksh & sh. In that case issue ps command .it will tell u.If u start another shell inside,then u have to grep and check with PPID.. hi Howard, ur command will give u the default shell, not the current shell. Thanks, niru
