Machine Type: i686-redhat-linux-gnu
Bash Version: 3.2
Patch Level: 25
Release Status: release
Description:
When I use the 'exec' built-in to redirect standard output
for a script, and then also use explicit redirection on
other commands, pointing both to the same output file,
I get unpredictable (but repeatable) results with the output
out of order.
Repeat-By:
The following script:
#!/bin/bash
>/tmp/foo
exec 1>/tmp/foo
echo a
echo B >>/tmp/foo
echo c
echo D >>/tmp/foo
echo e
echo F >>/tmp/foo
...should produce the following contents in /tmp/foo:
a
B
c
D
e
F
...but instead it produces:
a
c
e
F
Fix:
I am at a loss for how to understand this behavior -- sorry,
I can't suggest a fix. :-(
