Question: Default shell of the logged in User
Answer: There are many ways to find the default shell.
a)
By checking the last column in the /etc/passwd file ( grep –i
username /etc/passwd )
Eg:
[vjsujay@cheetah:/home/vjsujay]#grep -i vjsujay /etc/passwd
vjsujay:x:48153:63002:Sujay-kumar:/home/vjsujay:/bin/ksh
b)
By displaying the value of global environment variable SHELL
( echo $SHELL )
Eg: [vjsujay@cheetah:/home/vjsujay]#echo
$SHELL
/bin/ksh
NOTE: This will give
correct default shell name as output as long as your current shell is your
default shell
c)
By using the command echo $0
Eg: [vjsujay@cheetah:/home/st39422]#echo $0
-ksh
