IMNSO sed is the wrong tool here, awk can deal with the
password file much easier than sed and should handle just
about any input just so long as it doesn't add any :'s to the
lines that we are trying to mungle the password out of:
BEGIN {FS=":"; OFS=":"; ORS=""}
// {if (NF==10) {
print $1,"(password):"
for (n = 3; n <=NF; n++) print $n,"";
} else
print $0;
print "\n";
Defantily works on diff, diff -u and diff -c.
