echo
won't expand escape sequences. Consider printf.echo "Name:\t$value"printf 'Name:\t%s\n' "$value"Backslash escapes like \t and \n are not
expanded by echo, and become literal backslash-t, backslash-n.
printf does expand these sequences, and should be used
instead.
Other, non-portable methods include echo -e '\t' and
echo $'\t'. ShellCheck will warn if this is used in a
script with shebang #!/bin/sh.
If you actually wanted a literal backslash-t, use
echo "\\t"None
