| I am having a little problem running a simple awk command.
I need the entire string output twice, but when I try
c:\>dir /b | gawk '{print $0 " " $0}'
if only get one output item
This is using cygwin's gawk on a windows box ( excuse the 'w' word )

| Janis,
thanks but this also does not work.
this is a simple example of what is happening:
C:\BIN>echo one two | gawk '{print $1 " " $2}'
one two
C:\BIN>echo one two | gawk '{print $1 " " $1}'
one one
C:\BIN>echo one two | gawk '{print $0 " " $0}'
one two
the last command I would expect to be:
one two one two

| I have always had success with the quotes I used. But just to give it a
try:
c:\>echo one two | gawk "{print $0 ' ' $0}"
gawk: {print $0 ' ' $0}
gawk: ^ invalid char ''' in expression
so here is some other output
c:\>echo one two | gawk '{print $0" some stuff " $0}'
some stuff one two
c:\>echo one two | gawk '{print $1" some stuff " $1}'
one some stuff one
c:\>echo one two | gawk '{print $1" some stuff " $2}'
one some stuff two
now the next 2 are a little interesting
c:\>echo one two | gawk '{print $0 " some stuff"}'
some stuff
c:\>echo one two | gawk '{print " some stuff " $0}'
some stuff one two
oh well just one of those windows thingies
works fine on linux ( no surprise there )

Will you PLEASE just do what Janis suggested days ago instead of
repeating all this nonsense that obviously will not work!!!!!

It should :-)
Try without the spaces maybe ?
$ echo one two | gawk '{print $0" "$0}'

I bet it's that darn CRLF thing again.
In other words, you are only seeing $0 one time because gawk is printing
$0\r" "$0
dir /b | gawk '{sub(/\r/,""); print $0 " " $0}'

Compiled with a Windows compiler, perhaps with specific modifications
for use in the Windows console environment. The Cygwin version is
intended for use in the Cygwin environment though it does seem to work
in the pure Windows environment (Cygwin is installed and configured
for DOS style files). I seem to remember that they fail differently
when asked to do Unix specific things like bidirectional pipes and
direct read/write to TCP/IP, though they both fail.

What "this" are you talking about.

All three calls do not match what I suggested to try out; re-read what
I had written...[color=darkred]
