These shouldn't make any difference. The limit is on the size of the expanded shell command line.
Really?
$ M=0; N=0; for W in `find /usr -xdev 2>/dev/null`; do M=$(($M+1)); N=$(($N+${#W}+1)); done; echo $M $N 156304 7677373
vs.
$ /bin/echo `find /usr -xdev 2>/dev/null` bash: /bin/echo: Argument list too long
For the first case, the shell never tries to pass the list as command arguments. It builds the list internally, limited only by memory size, and processes the words one by one. As a final test case, by using the shell's builtin 'echo' the whole 7-plus megabytes gets echoed to the terminal:
$ echo `find /usr -xdev 2>/dev/null` (no errors -- just lots of output)
Anyway, the "for i in `ls ...`" solution breaks for paths that include embedded white space.
