I would embed the necessary bash commands in the awk subscript using its (awk's) system command. 

I would embed the necessary bash commands in the awk script using its (awk's) system command: 

system ( "useradd -m -G accts -c " $1 $2) system ( "echo " $3 "| passwd --stdin " $1) system ( "mkdir -p " $5) system ( "chown " $2 $5)

system ( "useradd -m -G accts -c " "\"" $1 "\" " $2) # Step 6 (1) system ( "echo " $3 "| passwd --stdin " $2) # Step 6 (2) system ( "mkdir -p " $5) # Step 7 system ( "chown " $2 " " $5) # Step 7

Here is code to test the above fragment: 

awk -F\\t '{ print "useradd -m -G accts -c " $1 $2 print "echo " $3 "| passwd --stdin " $1

awk -F: '{ print "useradd -m -G accts -c " "\"" $1 "\" " $2 print "echo " $3 " | passwd --stdin " $2

print "chown " $2 $5

print "chown " $2 " " $5 print "" }' users.txt | less

Step 13 can be acomplished by re-running the Step 7 code: 

awk -F\\t '{
      system ( "mkdir -p " $5)                               # Step 7 & 13
      system ( "chown " $2 " " $5)                           # Step 7 & 13 

For RH, at least, we will be able to it all in plaintext.  I would capture the user table as a text file (users.txt) & process it using awk.  I would embed the necessary bash commands in the awk subscript using its (awk's) system command. 

#! /bin/bash
     .
     .
     .
awk -F\\t '{
      system ( "useradd -m -G accts -c " $1 $2)
      system ( "echo " $3 "| passwd --stdin " $1)
      system ( "mkdir -p " $5)
      system ( "chown " $2 $5)
   }' users.txt

# test code
awk -F\\t '{
      print "useradd -m -G accts -c " $1 $2
      print "echo " $3 "| passwd --stdin " $1
      print "mkdir -p " $5
      print "chown " $2 $5
   }' users.txt

The excersise gives a table of 10 users in Table _ _ on page -.  We are instructed to do the following for each of them: 

The excersise gives a table of 10 users in Table 2.1. 

We are given 14 steps to complete the "Migration from Windows NT4 Workstation System to Samba-3".  We are instructed to do the following for each user: 

6. For each user who uses this system (see Table 2.1), execute the following:

root# useradd -m -G accts -c "Name of User" "LoginID"
root# passwd "LoginID"
Changing password for user "LoginID"
New Password: XXXXXXXXX <-- the password from the table
Retype new password: XXXXXXXXX
root# smbpasswd -a "LoginID"
New SMB password: XXXXXXXXX <-- the password from the table
Retype new SMB password: XXXXXXXXX
Added user "LoginID"

7. Create the directory structure for the file shares by executing the following:

root# mkdir -p /data
root# chown alan /data
root# for i in james suzy ursula peter dale eric jeannie russell
> do
> mkdir -p /data/$i
> chown $i /data/$i
> done
root# chgrp -R accts /data
root# chmod -R ug+rwxs,o-r+x /data

13. Verify that the files are being copied correctly from the Windows NT4 machine to the Samba-3 server. This is best done on the Samba-3 server. Check the contents of the directory tree under /data. This can be done by executing the following command:

root# ls -aR /data

root# chown alan /data
root# for i in james suzy ursula peter dale eric jeannie russell
> do
> chown $i /data/$i
> done
root# chgrp -R accts /data
root# chmod -R ug+rwxs,o-r+x /data

Discussion

Steps 6 & 7 can be placed in a script, provided we know how to interact with useradd, passwd, & smbpasswd.  Let's look at the supplied versions & their capabilities in our selected distros. 

Notes

• "???" in Version indicates no response to -v, -V, or --version.
  This indicates the need for a mandate to provide a version option in all commands,
  preferably a uniform one like -V.

• PT = Plain Text

• PTA = Plain Text command line Argument

A secure method to add samba users & their passwords would be to provide a table of user information which includes the encrypted password.  There are two flaws in this approach: 

1. Even though useradd can accept an encrypted password, there is no documented way for smbpasswd to do this. 
2. All the documentation I can find on crypt (RH et al.) & mcrypt (Debian) is abominable.  There is the implication that you can pipe a plaintext password through these commands to get an encrypted password for useradd, but no straightforward method for doing so.             RTFM...RTFM?...WAFRFM,AH!!
