# awk -F"[][ ]" 'NF>4{a[$3]=(a[$3]?a[$3] RS:z) $(NF-1)}END{for(i in a) {print i":" RS a[i]}}' tst
Full:
manatsu
TXT:
manachan

awk -F"[][ ]"	use the square braket as well as the space charactere as fields separator
'tolower($3)~/full<pipe>txt/	According to those field separators if the third field set to lower case matches "full" or "txt"
{a[$3]=(a[$3]?a[$3] RS:z) $(NF-1)}	then build associative array indexed by the value of $3 and concatenate in element a[$3] the field N-1
a[$3]?a[$3] RS:z	just means : if a[$3] is true (means : is not null and not empty and not equal to zero), then assign it with itself + a record separator(new line), otherwise assign z (wich defaulty has not been assigned so its value is empty)
a[$3]=(a[$3]?a[$3] RS:z) $(NF-1)	concatenate the N-1** field to the previous expression and store it into the a[$3] element
	(**)since space " " and closing square bracket "]" are record separator)
END{	once the whole input file has been processed
for(i in a) {	for all index existing in array a
print i":" RS a[i]}}'	Display the name of the index with ":" then new line, then the element that contains the list of concatenated entries found for that index

lcp_mlehash

LCP_MLEHASH(8)							   User Manuals 						    LCP_MLEHASH(8)

NAME

       lcp_mlehash - generate a SHA-1 hash of a TXT MLE binary file suitable for use in a TXT launch control policy

SYNOPSIS

       lcp_mlehash [-v] [-c cmdline] [-h] mle-file

DESCRIPTION

       lcp_mlehash is used to generate a SHA-1 hash of the portion of an executable file that contains the Intel(R) TXT measured launched environ-
       ment (MLE).  In the MLE binary file, the portion of the file to be used as the MLE is specified in the MLE header  structure.   If  verbose
       mode is not used, the output is suitable for use as the mle-file to the lcp_crtpol and lcp_crtpolelt commands.

OPTIONS

       mle-file
	      File name of the MLE binary.  If it is a gzip file then it will be un-ziped before hashing.

       -v     Verbose mode, display progress indications.

       -c cmdline
	      Specify  quote-delimited	command  line. It is important to specify the command line that is used when launching the MLE or the hash
	      will not match what is calculated by SINIT.

       -h     Print out the help message.

EXAMPLES

       lcp_mlehash -c "logging=memory,serial,vga" /boot/tboot.gz > mle-hash
