@Don Cragun: Thanks for drawing the attention to these aspects. As I said, tinkering with system files is always a thing to consider twice.
Btw, you should add a s/:,/:/ to your sed cmd in case $Usr would be the first in $Grp.
Good catch. And doing that in the ed script would be something like:
with the .g needed in front of the second s command to preserve the 0 exit status if $Grp was found and $Usr wasn't the first user in the group.
One should also make sure that the script isn't adding a user to the "nobody" group nor the "nogroup" group (or other groups depending on the OS on the machine), but I didn't bother because the idea of editing /etc/passwd, /etc/group, or any corresponding shadow files because usermod won't work (without explaining why usermod won't work) still just seems wrong.
:confused:
I have a script that Cats a flat database file which contains 12 columns into sed. I want to add a 13th column which includes " ,2005-08-29 " * The date needs to be the current date.
This 13th column would be appended to the end of each line.

append
append(1T) Tcl Built-In Commands append(1T)__________________________________________________________________________________________________________________________________________________NAME
append - Append to variable
SYNOPSIS
append varName ?value value value ...?
_________________________________________________________________DESCRIPTION
Append all of the value arguments to the current value of variable varName. If varName doesn't exist, it is given a value equal to the
concatenation of all the value arguments. The result of this command is the new value stored in variable varName. This command provides
an efficient way to build up long variables incrementally. For example, ``append a $b'' is much more efficient than ``set a $a$b'' if $a
is long.
EXAMPLE
Building a string of comma-separated numbers piecemeal using a loop.
set var 0
for {set i 1} {$i<=10} {incr i} {
append var "," $i
}
puts $var
# Prints 0,1,2,3,4,5,6,7,8,9,10
