In contrast to wc, grep with -l or -q option stops reading the input when a match has occurred.
In this case a
(stop if any character is met) seems sufficient.
Because grep returns an exit status it becomes quite simple:
Note that -q is not portable. If this is an issue, use the -l option and suppress output.

shtool-mdate
SHTOOL-MDATE.TMP(1) GNU Portable Shell Tool SHTOOL-MDATE.TMP(1)NAME
shtool-mdate - GNU shtool pretty-print last modification time
SYNOPSIS
shtool mdate [-n|--newline] [-z|--zero] [-s|--shorten] [-d|--digits] [-f|--field-sep str] [-o|--order spec] path
DESCRIPTION
This command pretty-prints the last modification time of a given file or directory path, while still allowing one to specify the format of
the date to display.
OPTIONS
The following command line options are available.
-n, --newline
By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is
omitted.
-z, --zero
Pads numeric day and numeric month with a leading zero. Default is to have variable width.
-s, --shorten
Shortens the name of the month to a english three character abbreviation. Default is full english name. This option is silently ignored
when combined with -d.
-d, --digits
Use digits for month. Default is to use a english name.
-f, --field-sep str
Field separator string between the day month year tripple. Default is a single space character.
-o, --order spec
Specifies order of the day month year elements within the tripple. Each element represented as a single character out of ``"d"'',
``"m"'' and ``"y"''. The default for spec is ``"dmy"''.
EXAMPLE
# shell script
shtool mdate -n /
shtool mdate -f '/' -z -d -o ymd foo.txt
shtool mdate -f '-' -s foo.txt
HISTORY
The GNU shtool mdate command was originally written by Ulrich Drepper in 1995 and revised by Ralf S. Engelschall <rse@engelschall.com> in
1998 for inclusion into GNU shtool.
