/usr/bin/script doesn't wait for command to finish before exiting

[Fergus Henderson]

The script command fails to wait for the command that it is executing to finish.
For example, the command

  /usr/bin/script -c "sleep 1; echo foo" < /dev/null; echo bar

produces the output

  Script started, file is typescript
  Script done, file is typescript
  bar
  foo

and an empty "typescript" file, whereas the correct output should be

  Script started, file is typescript
  foo
  Script done, file is typescript
  bar

and the "typescript" file should contain "foo".

The attached patch fixes the problem.

Hi Fergus,

Thanks for reporting this bug! We could fix it in Ubuntu, but i would really prefer if this could be fixed upstream as it is something that affects the functioning of the program.

Instructions on how to report bugs against util-linux-ng can be found here.
http://userweb.kernel.org/~kzak/util-linux-ng/

Thanks!

If you are unable to report it upstream for any reason, please let me know and I will see if I can assist.

Hi Fergus,

Is the bug still an issue in the newer util-linux packages on Intrepid or Jaunty?

If so, we can look incorporate your patch if it is still applicable.

I don't know if it is still an issue on Intrepid or Jaunty. I don't
know how to access those.
If you do have access to a system running Intrepid or Jaunty, it's
very easy to test: just run the command

    /usr/bin/script -c "sleep 1; echo foo" < /dev/null; echo bar

and if the output is

   Script started, file is typescript
   Script done, file is typescript
   bar
   foo

then the bug is still present.
