The /etc/shells file is missing.
Hi the /etc/shells file is missing on some of development boxes. Is this ok? Where can I find this file?

---------- Post updated at 07:07 AM ---------- Previous update was at 07:07 AM ----------

I have solaris, linux, aix and hpux machines and on all of these machines the /etc/shells file is missing.

Unless you plan to restrict shells using /etc/shells file, you can ignore the missing /etc/shells.

Solaris 10, hpux by default don't have the file.

Thanks..! but I need to write script which needs to find the shells supported by the system. I just thought of doing cat /etc/shells, so if this is missing from where can i get the information.

You may have to write a script to see what shells are on your system. Look at man getusershell.
Code:

getusershell is Solaris-specific. It is not portable and is a C function

You can prepare a list of known shells and check their availability. Something like this:
Code:
for sh in bash ksh93 ksh88 ksh sh dash zsh csh tcsh; do
  if which $sh >/dev/null; then
    echo "Find $sh"
  fi
done
