I think i know whats the problem. i tried to print out the line number. it seems the script reads those files as one file. What can we do so that the script can read one file than loop for 2nd file? i try to put unix command but don't know how to pass the file variable to replace @Files. Any advise?

ls file*.txt > list
for i in `cat list`
do
Perl script
done
output: Eg: each file contain 17 lines.

gets
gets(n) Tcl Built-In Commands gets(n)
__________________________________________________________________________________________________________________________________________________NAME
gets - Read a line from a channel
SYNOPSIS
gets channelId ?varName?
_________________________________________________________________DESCRIPTION
This command reads the next line from channelId, returns everything in the line up to (but not including) the end-of-line character(s), and
discards the end-of-line character(s).
ChannelId must be an identifier for an open channel such as the Tcl standard input channel (stdin), the return value from an invocation of
open or socket, or the result of a channel creation command provided by a Tcl extension. The channel must have been opened for input.
If varName is omitted the line is returned as the result of the command. If varName is specified then the line is placed in the variable
by that name and the return value is a count of the number of characters returned.
If end of file occurs while scanning for an end of line, the command returns whatever input is available up to the end of file. If chan-
nelId is in nonblocking mode and there is not a full line of input available, the command returns an empty string and does not consume any
input. If varName is specified and an empty string is returned in varName because of end-of-file or because of insufficient data in non-
blocking mode, then the return count is -1. Note that if varName is not specified then the end-of-file and no-full-line-available cases
can produce the same results as if there were an input line consisting only of the end-of-line character(s). The eof and fblocked commands
can be used to distinguish these three cases.
EXAMPLE
This example reads a file one line at a time and prints it out with the current line number attached to the start of each line.
set chan [open "some.file.txt"]
set lineNumber 0
while {[gets $chan line] >= 0} {
puts "[incr lineNumber]: $line"
}
close $chan
