This simple a question sounds *very* much like a homework assignment.

Ronald and rich sorry for that. I have try using below script but why the result always add two lines (blank string) on the end of actual string?
set lines [lrange $lines 2 end]
puts $fp [join $lines “\n”]
Thanks for helps!
set lines [lrange $lines 2 end]
puts $fp [join $lines “\n”]

puts -nonewline $fd $something. [split \n] converts every line into a
string. If you have a regular file, which ends in \n, it will give you
an empty string at the end.

puts always adds an extra newline. If you want to stop it, use
