You're absolutely right in your approach to making the script more robust and I must admit there were several basic assumptions made by me that were possibly optimistic.
I did assume;
And again I'd say that I took yogeshkumkar at face value when I gave the advice, not that that is any excuse for sloppiness. I should have tested for file types incase there was a link or the likes, should have enclosed the variable to ensure that it worked around spaces etc.
I work in a fairly pressured production/dr/test/development environment. So have four of every machine from M9000's to T5120's where I always have the facility to test - possibly it has made me a little cavalier.
I'll try to remember that not everyone can restore Pb sized file systems in minutes if things go pear shaped

for
for(n) Tcl Built-In Commands for(n)
__________________________________________________________________________________________________________________________________________________NAME
for - ``For'' loop
SYNOPSIS
for start test next body
_________________________________________________________________DESCRIPTION
For is a looping command, similar in structure to the C for statement. The start, next, and body arguments must be Tcl command strings,
and test is an expression string. The for command first invokes the Tcl interpreter to execute start. Then it repeatedly evaluates test
as an expression; if the result is non-zero it invokes the Tcl interpreter on body, then invokes the Tcl interpreter on next, then repeats
the loop. The command terminates when test evaluates to 0. If a continue command is invoked within body then any remaining commands in
the current execution of body are skipped; processing continues by invoking the Tcl interpreter on next, then evaluating test, and so on.
If a break command is invoked within body or next, then the for command will return immediately. The operation of break and continue are
similar to the corresponding statements in C. For returns an empty string.
Note: test should almost always be enclosed in braces. If not, variable substitutions will be made before the for command starts execut-
ing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an
infinite loop. If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
ation), so changes in the variables will be visible. For an example, try the following script with and without the braces around $x<10:
for {set x 0} {$x<10} {incr x} {
puts "x is $x"
}
