       annotate-output - annotate program output with time and stream


       annotate-output program [args ...]


       annotate-output  will  execute  the specified program, while prepending
       every line with the current time and O for stdout and E for stderr.


       $ annotate-output make
       21:41:21 I: Started make
       21:41:21 O: gcc -Wall program.c
       21:43:18 E: program.c: Couldn’t compile, and took me ages to find out
       21:43:19 E: collect2: ld returned 1 exit status
       21:43:19 E: make: *** [all] Error 1
       21:43:19 I: Finished with exitcode 2


       Since stdout and stderr are processed in parallel, it can  happen  that
       some  lines received on stdout will show up before later-printed stderr
       lines (and vice-versa).

       This is unfortunately very hard to  fix  with  the  current  annotation
       strategy.   A  fix  would  involve switching to PTRACE’ing the process.
       Giving nice a (much) higher priority over the  executed  program  could
       however cause this behaviour to show up less frequently.

       The  program does not work as well when the output is not linewise.  In
       particular, when an interactive program asks for  input,  the  question
       might  not  be  shown until after you have answered it.  This will give
       the impression that the annotated program has hung, while it has not.

       annotate-output does not currently accept any command-line options,  so
       --help, --version, and that kind of stuff do not currently work (unless
       you install /usr/bin/--help ;) ).


       Accept --help, --version command-line options.

       Get rich with this very sophisticated piece of bash.

       This  program  is  community-supported  (meaning: you’ll need to fix it
       yourself).   Patches  are  however  appreciated,  as  is  any  feedback
       (positive or negative).
