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 print the input or print "OK" if the input
is enpty
Example correct use:
echo "Hello World" | ~/OkIfNoInput.sh
Hello World
echo "" | ~/OkIfNoInput.sh
OK
The ISSUE is when the string Contain "*" the results are very estrange. or
"*[space]"
echo "* Hello World *" | ~/OkIfNoInput.sh

This is an expected result?
I'm doing something wrong?
Or is this a bug in bash?
Kind Regards
