The shell is not very good at arithmetic, so for small numbers, I prefer working with just a string -- grow the string by one character in the loop, and once the string is x characters long, quit. But here, obviously, the number is large enough that the traditional way of doing this is better.

basename, dirname - extract portions of path names
SYNOPSIS
string [suffix]
[string]
DESCRIPTION
deletes any prefix ending in and the suffix (if present in string) from string, and prints the result on the standard output. If string
consists entirely of slash characters, string is set to a single slash character. If there are any trailing slash characters in string,
they are removed. If the suffix operand is present but not identical to the characters remaining in string, but it is identical to a suf-
fix of the characters remaining in string, the suffix is removed from string. is normally used inside command substitution marks within
shell procedures.
delivers all but the last level of the path name in string. If string does not contain a directory component, returns indicating the cur-
rent working directory.
EXTERNAL INFLUENCES

If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari-
able. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization
variable contains an invalid setting, and behave as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
