Which systems guarantee monotonic behavior for gettimeofday()? I can't think of any. I hope there's no behavior in nq which relies on monotonicity other than file naming, because otherwise you might run into some obscure issues.

Could you please add some usage examples or elaborate on when this tool would be useful? For example,

> building several targets of a Makefile

As opposed to `make && sudo make install` ?

> downloading multiple files one at a time

As opposed to `(wget url1 &) ; (wget url2 &)` ?

> or simply as a glorified `nohup`

As opposed to `nohup` ?

Thank you for making the comment I came to make!

The shells have had queueing for, well, a very, very long time....

I imagine it's useful if you don't know all the commands you want to queue at the beginning.

For example:

    nq ./my_awesome_analysis /data/complicated_file_with_long_name.dat

    # um... what's the next file? 

    ls /data 
    nq ./my_awesome_analysis /data/even_more_complicated_path.dat

    man rsync
    nq rsync -avh --progress out* somewhere_else.net:

For example: nq ./my_awesome_analysis /data/complicated_file_with_long_name.dat # um... what's the next file? ls /data nq ./my_awesome_analysis /data/even_more_complicated_path.dat man rsync nq rsync -avh --progress out* somewhere_else.net:

You don't need nq for that. Just kick off ./my_lame_analysis in the background whenever you want.

Earlier quoted context omitted.

Yes but then they will execute at the same time instead of sequentially.
