Bash Nitpicking on Redirections
This little excerpt from the bash man page explains the reason I just wasted 2 hours:
Note that the order of redirections is significant. For example, the command
ls > dirlist 2>&1
directs both standard output and standard error to the file dirlist, while the command
ls 2>&1 > dirlist
directs only the standard output to file dirlist, because the standard error was duplicated as standard output before the standard output was redirected to dirlist.

Not bash-specific. That is how the Bourne
shell has always been.
