As long as the length of your certificates is less than the limit LINE_MAX bytes on your system (the limit on your system can be found using:
Code:
getconf LINE_MAX

but should be at least 2048), the following will reformat your certificates to 72 characters per line, tell you how many times each certificate appeared in your input file, and tell you where any duplicates appeared in your input file:
Code:
#!/bin/ksh
awk '
BEGIN {	nl = 72	# Normalized Length of certificate data.
}
/-----BEGIN CERTIFICATE-----/ {
	incert = 1	# We are processing a certificate.
	ac[++cc] = 1	# Increment # of certifcates seen and set appearance
			# count for this certificate
	next
}
/-----END CERTIFICATE-----/ {
	# End of certificate data found; look for a match...
	for(i = 1; i < cc; i++)
		if(l[i] == l[cc] && cd[i] == cd[cc]) {
			# We found a matching certificate.
			printf("# %s %d dups certicate #%d\n",
				"Certificate ending on line", NR, i)
			ac[i]++		# Increment appearance count.
			cd[cc] = ""	# Delete this duplicate...
			l[cc--] = 0
			break
		}
	incert = 0	# We are between certificates.
	next
}
incert {# Gather certificate data.
	l[cc] += length($0)
	# NOTE: The following line will not work on some systems if certficate
	# data is more than LINE_MAX bytes long!
	cd[cc] = cd[cc] $0
}
END {	# Print results:
	for(i = 1; i <= cc; i++) {
		printf("# Certificate #%d, %d characters, appeared %d time%s\n",
			i, l[i], ac[i], ac[1] > 1 ? "s" : "")
		print "-----BEGIN CERTIFICATE-----"
		for(j = 1; j <= l[i]; j = j + nl)
			print substr(cd[i], j, nl)
		print "-----END CERTIFICATE-----"
	}
}' "${1:-certificates.txt}"

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.

This was tested using the Korn shell, but will work with any shell that handles POSIX standard variable expansions. If the file certificates.txt (or another file of your choosing passed as the 1st operand to this script) contains:
Code:
