Word count of lines ending with certain word

Hi all, I am trying to write a command that can help me count the number of lines in the /etc/passwd file ending in bash.

I have read through other threads but am yet to find one indicating how to locate a specifc word at the end of a line. I know i will need to use the wc command but when i attempt to combine this with grep it seems to do nothing at all. Below is the command i am entering:

cat /etc/passwd | wc | grep bash

If anyone can help me correct this and indicate where i am going wrong i'd be most grateful.

vipw(8) 						      System Manager's Manual							   vipw(8)

NAME
vipw - Edits the /etc/passwd file SYNOPSIS
/usr/sbin/vipw DESCRIPTION
You use the vipw command to edit the /etc/passwd file with the editor defined in the EDITOR environment variable. If the variable is not set, the default editor is vi. The vipw command performs basic consistency checks on the edited file. If a hashed indexed passwd existed previously, the vipw command uses the mkpasswd command to create recreate it. The command must not be used on systems that use extended security attributes since it cannot set or change them. You must be root to run this command. Only root and security administrators should have execute access to this command. Since the vipw command cannot effectively change all the attributes of users, it should not be used in a secure environment. The vipw command accesses the following files, and requires the listed permissions: ------------------------------ Permissions File ------------------------------ rw /etc/passwd rw /etc/passwd.pag rw /etc/passwd.dir rw /etc/ptmp rw /etc/ptmp.pag rw /etc/ptmp.dir ------------------------------ EXAMPLE
To edit the /etc/passwd file, type the following command and add the required line entry: vipw FILES
Specifies the command path RELATED INFORMATION
Commands: passwd(1), passwd(4), adduser(8), mkpasswd(8) delim off vipw(8)
