Sorry for the repeat posting, that's NOT solved.
(Excuse the long post.)
Unless I'm missing something, this doesn't do what I wanted. I want
is the whole command *line*, not the portion of it that evoked the
script, the latter being the individual *command* within the command
line--confusing enough ;-) ? If I issue the example I gave in my OP:
echo -n "Starting..." ; more some-stuff | \
doStuff.pl - 3 > save-here.out ; echo "done."
Within doStuff.pl I want to obtain the command line, i.e. everything
from "echo" through to '"done."', or at least everything from "more"
through to "save-here.out". (As I wrote in my OP: "everything
including pipes and redirects, etc.") Its the reason I gave this
extended example command line as an example, including it spanning
lines.
PID->get_command() gives me just the script and it parameters. That
is, it gives the command, not the command line.
Trying to get Unix::PID to give the command of the ppid, yields
'-bash' (let's hope I'm doing things right!), so I presume that the
command *line* isn't considered a unit in this scheme of things--?
Put another way, the example above would yield five commands, each
whose parent is '-bash' and the command *line* isn't retained in the
PID hierarchy? This makes sense to me in that lines aren't
processes are such, so I can imagine the shell splitting into the
five piece, but it'd also mean that Unix::PID is very unlikely to be
any use to me :-(
(I know bash 3.0+ has a BASH_COMMAND env. var. and I'm looking into
installing a bash 3.0.x alongside Apple's 2.05b btw, but it'd be
nicer to have a solution that's not tied to a particular shell or
version.)
Thanks,
Grant
