i'm using plan9port (thanks, rsc) on linux for some 8 years now, for all

i've realized i never use the Esc key in Acme.
meanwhile, i often go through cycle of:

the man page of test(1) mentions "-l string" as string length operator
for -eq, -gt, etc.
but there seems to be nothing in the plan9port's src/cmd/test.c, nor
in 9p.io/sources/cmd/test.c
is there any implementation of this floating around?
i was mildly surprised that p9p awk handles NUL-terminated records just fine.
either via -v 'RS=\0', or via BEGIN { RS="\0" }
needed it to handle output of git status --porcelain=v2
thanks, that did the trick indeed.
given multi-line dot, spanning only part of a file, how do i construct
an Edit command to remove lines matching certain regular expression?
wanted to delete lines starting with one particular character; without
leaving an empty line behind, thus Edit s/X.+//d is not sufficient.
does anybody have a version of Rc that allows unquoted equality sign?
having to quote the character get a bit annoying on POSIX systems (plan9port)
was there any attempt at using Slack through Acme?
the default desktop GUI, a browser AFAICT, is taking 1+ GB of RAM
after a few hours
given
pathnames = ( foo/a.txt bar/b.txt baz/c.txt )
how do i construct arguments to test(1) that test for existence of
those files in one go?
wanted:
test -e foo/a.txt -o -e bar/b.txt -o -e baz/c.txt
assuming the pathnames may contain space characters.
rc is a thing of beauty.

i'm using plan9port mk on linux and just hit the environment+argument
length limit -- linux' execve($PLAN9/bin/rc, ... ) returns E2BIG because

the mkfile is:
TIMESTAMP_FILE:
how do i turn off output buffering in p9p Acme for particular fd?
a braindead linux application does dup(2), and proceeds using FD 3 as error
output, which results in buffered output in Acme.
