No. What you're seeing is evidence that the output from the curl command is using DOS <carriage-return><newline> line terminators instead of UNIX <newline> line terminators. The echo output is showing that htcount has been set to "1<cr>" (where <cr> is a carriage return character). Since <cr> is not a numeric character, the test utility is complaining that "${htcount}" expands to a non-numeric string that is not valid in an operand of the binary -ge test operator. Note that an easier way to see this is to use:

Code:

printf '%s' "$htcount" | od -bc

Try adding:

Code:

tr -d '\r'

to the pipeline before or after the grep command.
