Public bug reported: Using bash redirection with sponge does not work as expected. For example, this will make test_file empty:
sed 's/^/prefix/' test_file | sponge > test_file Instead, one should do this instead: sed 's/^/prefix/' test_file | sponge test_file I feel the man page should be updated to include this warning. ** Affects: moreutils (Ubuntu) Importance: Undecided Status: New ** Tags: documentation -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879077 Title: sponge's man page should include a warning on how not to use it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/moreutils/+bug/879077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
