Where can I read the argument list size limit? I fail to see anything relevant with ulimit -a or in proc or in pam's limits.conf.

check the man pages for the shells
usually they list the length of the command line buffer.
In 4.3 BSD, I believe the buffer was 10 kiB. -- which I
thought was deliriously excessive back before I understood
shell scripting and filename globbing.

That's true and interesting, but not really relevant to the xargs discussion. xargs doesn't use the shell command line buffer limit, but the *ARG_MAX limits from sysconf(3) and takes also the environment space into account.

Best,
Joachim
