Re^2: Execute by order

if you persist with ...using files and "while" as a queqe at its simplest, then you won't be able to do ...someone of those at same time, - especially on Windoze.

Why? In particular, why - especially on Windoze?

...depends on the implementation I suppose - I took it to mean using `while` to iterate thro' a list of simple commands i.e. no parallelism. On *NIX, I submit it is easy to modify the command strings to run a command in parallel ... which, IIRC, isn't possible on Windoze.

...at its simplest, by changing `command` to `command &`. However, by just doing the above, the backgrounded command will suspend if it needs to write to either device 1 or device 2 (STDOUT/STDERR in perl parlance), or read from device 0 (STDIN), so `command` is usually rewritten as `command >file 2>&1 &` to send all output from stdout and stderr to `file`. If you don't care about output from either stdout or stderr, the frequently seen idiom - `command >/dev/null 2>&1 &` - is used.

...but ...someone of those at same time..., to me at least, implies parallelism i.e. two, or more, commands running in parallel. A user level that continues to overstate my experience :-))	[reply]
