[Help-bash] Missing stdin in bash script.

[Jin Li]

Dear all,

I have one problem as below:
1. I have one script file, say 'test.sh':

#!/usr/bin/env bash
cat > xxx.txt

2. Running command as:

$ ./test.sh <<< aaa

Get the error:

cat: -: Stale file handle


3. Running like below works:

echo "aaa" | ./test.sh


Hope you guys can give me some clues about the error. Thanks.

Best regards,
Jin
