Yes. Same suggestion as Herbert Xu's, who stated: 'a perfectly adequate work-around in "cat"' Unfortunately, that work around is neither perfect nor adequate. I'd call it painful, as: read MAX </proc/sys/kernel/pid_max is so much more efficient (about 25x faster, on my box) than: MAX=$(cat /proc/sys/kernel/pid_max) I hope you noticed, this is a problem _only_ with /proc files holding integers >9. No such problems with files containing strings.
