Still I'd like to strip it down a bit, given your system allows for "process substitution" and the relevant / applied grep options. Try:
Code:
grep -hirof file.txt * | sort -u | tee >(grep -vif- file.txt | sed 's/$/|missing/') | sed '/|/!s/$/|found/'

Definitely agreeing with you Smilie
I just shook my head when I saw it ha ha!
I just thought, do what they say and trust it Smilie

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...] zegrep [grep-flags] [--] pattern [file ...] zfgrep [grep-flags] [--] pattern [file ...] DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1). The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern argument. zegrep calls egrep(1), while zfgrep calls fgrep(1). EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0. SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1) AUTHORS
