If it's a local user, the 7th field of /etc/passwd is their shell. Are you looking for the currently preferred shell?

-1 The default login shell is not necessrily the one currently running. –  rahmu May 3 '12 at 12:05
#!/bin/sh  
ps h -p $$ -o args='' | cut -f1 -d' '
  • ps process list
  • h do not print column headers
  • -p <PID> list only process id PID
  • $$ replaced by the shell with current PID
  • -o args print the command line, no other information
  • cut cut the output into parts
  • -f1 print only the first field
  • -d' ' use a space as a field separator

    $ ./testje

    /bin/sh

On Mac OX X I get an additional line with the header ARGS. With -o args='' you can remove the header –  Matteo May 3 '12 at 18:50
