Shows only default shell

Submitted by Ray Foulkes (not verified) on Sat, 04/14/2012 - 08:08.

Be careful, as far as I can determine the echo $SHELL does not tell you the actual shell in use, it only tells you the default shell. For example, if you put that command in a script which is invoked on a different shell, you will not see the ACTUAL shell used by the script.

Place hashpling/bin/tcsh at the beginning of a script with echo $SHELL in it and run the script from bash. It will report /bin/bash not /bin/tcsh.

Correct - Shows Only the $SHELL Environment Variable

Submitted by Aaron Newton (not verified) on Sat, 07/28/2012 - 12:55.

Ray is correct - this only shows the $SHELL environment variable. You can check using the following commands ($ is terminal cursor):

$set | grep SHELL
SHELL=/bin/bash
$ ksh -c 'echo $SHELL'
/bin/bash

What you could try instead is the '$0' variable:

$ ksh -c 'echo $0'
ksh
aaron@zebrafish:~/oblivion/words$ echo $0
bash

'$0' is the name of the running process. See http://www.tldp.org/LDP/abs/html/othertypesv.html
