Full Discussion: Set password in bash script without manual entry-Solaris 10
Operating Systems Solaris Set password in bash script without manual entry-Solaris 10 Post 302963890 by MadeInGermany on Thursday 7th of January 2016 03:29:55 PM

The following is pasted from various scripts, use it with care!
Code:
PATH=/bin:/usr/bin:/usr/sbin:/usr/sfw/bin:/opt/csw/bin
export PATH

# Solaris has no tool to set a password non-interactively.
# Using "expect" has many risks. So we directly edit /etc/shadow.
sol_pwd()
{
ETCSHADOW=/etc/shadow
DATECHG=`perl -e 'print int time/86400'`
# Backup with owner/permission
if
  cp -p ${ETCSHADOW} ${ETCSHADOW}- &&
  cp -p ${ETCSHADOW} ${ETCSHADOW}.aux &&
# Overwrite the files; owner/permission and line order remains
  awk '
    BEGIN { FS=OFS=":" }
    ($1==user) { $2=hash; $3=datechg }
    { print }
  ' user="$ID" hash="$HASH" datechg="$DATECHG" < ${ETCSHADOW} > ${ETCSHADOW}.aux
then
  # *LK* in pw-hash and 0 in lastchg was overwritten. passwd -u is not necessary
  mv -f ${ETCSHADOW}.aux ${ETCSHADOW}
fi
} # sol_pwd

# main

echo "Enter user:"
read ID
echo "Enter pw:"
read PASS
if [ -z "$ID" ] || [ ${#PASS} -lt 3 ]
then
  exit
fi
HASH=`echo "${PASS}" | openssl passwd -stdin` || exit
sol_pwd

getusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

	 /bin/bash		    /bin/csh
	 /bin/jsh		    /bin/ksh
	 /bin/ksh93		    /bin/pfcsh
	 /bin/pfksh		    /bin/pfsh
	 /bin/sh		    /bin/tcsh
	 /bin/zsh		    /sbin/jsh
	 /sbin/pfsh		    /sbin/sh
	 /usr/bin/bash		    /usr/bin/csh
	 /usr/bin/jsh		    /usr/bin/ksh
	 /usr/bin/ksh93 	    /usr/bin/pfcsh
	 /usr/bin/pfksh 	    /usr/bin/pfsh
	 /usr/bin/sh		    /usr/bin/tcsh
	 /usr/bin/zsh		    /usr/sfw/bin/zsh
	 /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.

NOTES

       Restricted shells should not be listed in /etc/shells.
