How to read a space in bash - read will not
Many people have shown how to keep spaces when reading a line in bash. But I have a character based algorithm which need to process each end every character separately - spaces included. Unfortunately I am unable to get bash read to read a single space character from input.
while read -r -n 1 c; do
printf "[%c]" "$c"
done <<< "mark spitz"
printf "[ ]\n"
yields
[m][a][r][k][][s][p][i][t][z][][ ]
I've hacked my way around this, but it would be nice to figure out how to read a single any single character.
Yep, tried setting IFS, etc.
