I'm appending a line before a pattern and after another pattern(;) but omitting the first pattern - same as if comes duplicates before the second pattern.
Also, I'm adding a word before the first pattern -

fblocked
fblocked(n) Tcl Built-In Commands fblocked(n)
__________________________________________________________________________________________________________________________________________________NAME
fblocked - Test whether the last input operation exhausted all available input
SYNOPSIS
fblocked channelId
_________________________________________________________________DESCRIPTION
The fblocked command returns 1 if the most recent input operation on channelId returned less information than requested because all avail-
able input was exhausted. For example, if gets is invoked when there are only three characters available for input and no end-of-line
sequence, gets returns an empty string and a subsequent call to fblocked will return 1.
ChannelId must be an identifier for an open channel such as a Tcl standard channel (stdin, stdout, or stderr), the return value from an
invocation of open or socket, or the result of a channel creation command provided by a Tcl extension.
EXAMPLE
The fblocked command is particularly useful when writing network servers, as it allows you to write your code in a line-by-line style with-
out preventing the servicing of other connections. This can be seen in this simple echo-service:
# This is called whenever a new client connects to the server
proc connect {chan host port} {
set clientName [format <%s:%d> $host $port]
puts "connection from $clientName"
fconfigure $chan -blocking 0 -buffering line
fileevent $chan readable [list echoLine $chan $clientName]
}
# This is called whenever either at least one byte of input
# data is available, or the channel was closed by the client.
proc echoLine {chan clientName} {
gets $chan line
if {[eof $chan]} {
puts "finishing connection from $clientName"
close $chan
} elseif {![fblocked $chan]} {
# Didn't block waiting for end-of-line
puts "$clientName - $line"
puts $chan $line
}
}
# Create the server socket and enter the event-loop to wait
# for incoming connections...
socket -server connect 12345
vwait forever
