I think it is cool.
Oleg (author of task.ijs) produced lots of well thought out additions to
J. But even before his work, most of my use of J (especially in terms of
other people using my work) has been in J scripts.
J script of two sorts - #! shell scripts and the same but invoked as cgi
from an Apache web server. In the case of #! scripts, they are run from
a command line in either Linux or OS X (i.e. 'nix environments). I have
several "system admin tasks" that are started up and left running
indefinitely looping on a timer (typically between 1 second and 1 minute).
The cgi scripts start on demand from a browser call to the web server.
I have also used J #! scripts that wait on sockets activity from some
external (perhaps remote) process.
Key issues (for me) are how to pass standard input/output between
scripts/commands where some are J and others are not, and how to pick up
parameters from a browser user interacting with the web server.
I have sometimes posted descriptions of the tools I use (not as general
or "elegant" as those proposed/written by Oleg) and I am happy to share
such information with anyone interested.

Hi, All.
It's interesting for me. Does anybody usually use J scripts instead of Bash
scripts. Is it cool? Mb. there are examples & tutorials & *.pdf s about
this topic (any docs in addition to system/main/task.ijs )?
