Hi All.
H have the next bash script code.:
#!/bin/sh
# Pring OK on empty input,
# Print input on non-empty input
read INPUT
if [ -z "$INPUT" ]; then
echo OK
else
echo $INPUT
while read INPUT; do
echo $INPUT
done
fi
The function read one input and
Sorry I forgot the main version.
I have tested in: all show the same issue.

Cleanliness.
Not polluting the global namespace.
Ensuring the function can't be called from outside a function.
It's a trite example, but

I thought Bash always first splits the identifier from the subscript,
then checks which attributes the variable has set. If it has the
associative array attribute plus a subscript then the subscript is
only processed for expansions and the resulting string is used as the
key. If the associative arr

While I was developing a small script, I thought about how to use -N flag
to a greater extent. Although -N in its own is very limited. It does serve
the purpose but not what I need. I also discussed this in #bash freenode,
and got some ideas like:
pgas: while read -n1 d;do case $d in '')brea

IFS=. read -ra octets <<< "$ip"

I find myself in need of something along the lines of Python's
`re.split` and `re.findall` all the time. E.g. splitting an ip into an
array of octets.

Any reason to justify this instead of using a simple loop?

Hi,
According to ''help read'' we can specify -N[chars] to trigger return
automatically. Is it possible to approach read differently?
For example: $re is some regular expression
read -N$re -p "Enter two or three digits to continue " getInput
The above is much of a pseudo-code but I hope you
