using this silly batch code I got (what I believe to be) all errosr
reported by dmesg:
_OFL_PRFX=dmesg_$(whoami)_$(date +%Y%m%d%H%M%S);

cat ${_OFL} | grep -i "${_2CHCK}" > "${_OFL2}"
ls -l ${_OFL2}
wc -l ${_OFL2}
kwrite ${_OFL2} &
#
_CUT_HERE="---\[ cut here \]---"
_END_TRACE="\] ---\[ end trace "
_OFL04=""
_IFL="${_OFL}"
_LNS=$(wc -l ${_IFL} | awk '{print $1}')
echo "// __ \$_LNS: |$_LNS|"
_FND_TF=0
_IXL=0
while IFS= read -r _L; do
if [ $_FND_TF -eq 0 ]; then
_LCTH=$(echo "${_L}" | grep --regexp="${_CUT_HERE}")
if [[ ! -z ${_LCTH} ]]; then
_KRTM=$(echo "${_LCTH}" | awk -F' ' '{print $2}')
_KRTM=${_KRTM%?} # removing last char
echo "// __ \$_KRTM: |$_KRTM|"
_OFL04="${_OFL_PRFX}_${_KRTM}_cut_here.log"

_OFL04=""

else
echo "// __ |$_FND_TF| [$_IXL/$_LNS): |$_L|"

done < "${_IFL}"
ls -l "${_OFL_PRFX}_"*"_cut_here.log"

I *think* it should be harmless, but if not, you'll have to upgrade to a sufficiently newer kernel version to get the fix. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

Is there such a thing? Do people take it seriously? It's more that I'm not sure how you manage to write or read that quickly or easily. I could *do* it, on the read side at least, but it would take work; it's not anything close to readable. If it works for you, then it's not a fatal defect by any means, but it does tend to get in the way when sharing code with others (as here). That said, yes, I do tend to use longer (descriptive, not abbreviated) variable names and include moderately extensive comments in my shell scripts, just as in my other code. I find that it helps greatly in understanding what I've written, both at the time and when revisiting it later. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

I do quite a bit of stuff in bash, and the single, most expert help in the form of good practice teaching was from Jon LaBadie, on the amanda list. Tricks that I didn't know bash could do, are both efficient and child's play for Jon. Like me, he's been at it for a long time, and growing less active on the amanda list. Me, I make noise just to let folks know the old fart is still around, or when I need help. My next b-day in about 6 weeks, will be my 86th.

Is there such a thing? Do people take it seriously? Not enough, unfortunately. Way too many people just throw together some stuff that *looks* like it works (because they didn't test it properly), and then it goes into production and becomes a landmine just waiting to explode. The code in question had several quoting errors, and was using internal shell variables that didn't contain any lowercase letters. Also, for some reason, almost all of the variables began with the _ character. I have no idea why, but it certainly doesn't help readability. I didn't analyze it beyond that.
