Description:
using the script:
#!/bin/bash
TMPFILE=$(mktemp /tmp/tmp.XXXX)
for a in this is a test; do
if [ $a == 'a' ]; then
>&2 echo b
fi
done 2> >(echo "test!"> "$TMPFILE")
#touch "$TMPFILE"
if [ -s "$TMPFILE" ]; then
echo temp file is not empty
else
echo temp file is empty
fi
echo "Contents of $TMPFILE"
cat $TMPFILE
rm $TMPFILE
I get the output of:
temp file is empty
Contents of /tmp/tmp.LGvR
test!
if I touch or cat the TMPFILE before the test, it behaves as expected.
