This is both wrong (insecure) and clumsy. You can't create a temp file
this way. If the file already existed, then you're using someone else's

Sorry about delay, for some reason Google put your emails in SPAM. Also, I
don't really read much email on Sunday. I was "busy" building up my planets
in GOFA after church. And watching some TV. Pretty much didn't think about
email at all, because I do all that "other stuff" on my tablet, not my PC

Thanks for the training. I appreciate people pointing out my errors, that's
how I learn too. I'll blame GMAIL for the mish-mash. I don't have as good a
control of it as I would like (sorry). I'm always forgetting about people
who put LFs in a file name. That is just so weird, to me. I should rememb

The Gregorian calendar has 14 different year layouts: 7 non-leap-years
beginning with Sunday through Saturday, and 7 leap-years beginni

Hi all,
Thank you very much for providing me more information, I am getting more
confused. but learning more.
I tried this one, but failed if the folder has more than one file name (eg
*.csv) in that folder.
find . -maxdepth 2 -mindepth 2 -type f -name '*.csv' -o -name '*.txt' |\
egrep '^\./[0

Seriously, use this one:
find . \( -iname '*.txt' -o -iname '*.csv' \) -exec bash -c '
for f; do
IFS=/ read -ra part <<< "$f"
print
I've "squirreled" that one away on GitHub, in a gist. Thanks.

Here is another problem with the following script
find . \( -iname '*.txt' -o -iname '*.csv' \) -exec bash -c '
for f; do
IFS=/ read -ra part <<< "$f"
printf "%-10.10s %-10.10s %-20.20s %5d\n" \
"${part[1]}" "${part[2]}" "${part[3]}" "$(wc -l < "$f")"
done
' _ {} +

I've been approached by some HPC system administrators (who have the
unenviable task of supporting thousands of users) who have requested a
new feature in bash: a system startup file with a fixed name (e.g.,
/etc/bashenv) that is sourced by every instance of bash. The initial
request was for somet

Hey,
As an administrator, when I faced this issue I usually used some
wicked sourcing in standard bash startup files to get one global file
that gets sourced by default (last time I wanted one per group of
users, etc).
It would be useful; at least for me. How much harm can it do? If the
file is

This isn't an exhaustive analysis, but a quick check for 300 years
