[Samba] compare users in /etc/passwd versus /etc/samba/smbpasswd

[Colb, Andrew]

Comm command is ideal; it was built for this type of text processing
problem. It requires sorted ("collated") input lists. 

cut -d: -f1 /etc/passwd | sort > pass_f1   # provide sorted list of the
first field in the passwd file
cut -d: -f1 /etc/samba/smbpasswd | sort > smbpass_f1  # provide sorted
list of the first field in the smbpasswd file

then run

comm. -3 pass_f1 smbpass_f1 |more 
this will show two columns: first is entries unique to passwd, the
second column are entries unique to smbpasswd

comm command has several forms based on its output in three columns:
lines unique to file1, lines unique to file2 and lines found in both
files.
 
   comm -1 file1 file2  displays the items that are unique to file2  [-1
says omit results unique to file1 ]
   comm -2 file1 file2  displays the items that are unique to file1  [-2
says omit results unique to file2]
   comm -3 file1 file2  displays the items that are not common to file1
and file2
   comm -12 file1 file2  displays the items that are found in both file1
and file2

cut -f1 -d: to get the first field. Then sort, then diff, or a new
favorite: comm .
