My apologies if this has already been discussed:

I would just love a CYGWIN variable setting that would make cygwin ignore
the O_TEXT flag from all programs, thus bypassing any translation code in
cygwin1.dll.
May I suggest "notextmode", if not taken already :)

At work, we're aiming for maximum UNIX compatibility between all files
across win32/linux/solaris. All this O_TEXT stuff really, really gets in the
way. All our mounts are binmode, yet the fact that some programs set the
O_TEXT flag, and cygwin doesn't ignore it, will at some point add a stray
carriage return (see various threads on CRLF) in various pipes and
redirects.


We'd rather patch/wrap all non-cygwin utilities in our tool chain (i.e.
cl.exe) to output binmode only. Thinking of it, one could add an lf-ize
utility that invokes a program and adds CR to input while removing them from
output. This would keep the pipes clear of carriage returns.

lfize cl.exe | grep -v "^$"
lfize cat textfile | sed | awk

I freely admit not offering much thought to CTRL+Z.

Dan
