Hi again,
I managed to isolate the problem to the awk.exe.
Calling like this:
export FAWK; FAWK="awk -F^ --compat --source="
${FAWK}/"SIMU_included/{print \$3}" subst$1 >${TMPDIR}/$$
[ -s ${TMPDIR}/$$ ] && < ${TMPDIR}/$$ read SIMU
works only occassionally. But calling awk without redirection
first works 100% of the time.
export FAWK; FAWK="awk -F^ --compat --source="
${FAWK}/"SIMU_included/{print \$3}" subst$1
${FAWK}/"SIMU_included/{print \$3}" subst$1 >${TMPDIR}/$$
[ -s ${TMPDIR}/$$ ] && < ${TMPDIR}/$$ read SIMU
What is happening here? I am using the 1.5.16-1 version of Cygwin.

Hi there,
I am using the following convention to set variables in Bash:
awk -f /"SIMU_included/{print \$3}" subst$1 >${TMPDIR}/$$
[ -s ${TMPDIR}/$$ ] && < ${TMPDIR}/$$ read SIMU
For some reason parameter "SIMU" gets set randomly.
Could this be due W2K's buffering in creation of
temporary file ${TMPDIR}/$$? i.e read happens before file
is written on disk?
For some reason setting "ntsec" seems to help but this does not
explain the random success of file reading.
