I don't know much about the underlying lower operating system level. But I'd like to note, that it seems to work in *some* directories, but not in others: [lisp] $ for f in ${ls} {echo $f} 2cyr.txt draw.el iso646-de.el single-frame.el *much more output snipped* [lisp] $ mkdir test [lisp] $ cd test [test] $ touch alpha beta gamma delta [test] $ for f in ${ls} {echo $f} Wrong type argument: listp, #("alpha beta delta gamma" 0 25 (escaped t)) [test] $ for f in ${ls -l} {echo $f} total 0 usage: echo [-n] [object] -n terminate with a newline -h, --help output this help screen Does anybody know offhand where in the eshell code `for' is implemented?
