Assistance to calculate number of hugepages

Hi,

I am trying to count the number of hugepages & total usage being used by applications..

INPUT FILE
==========

Code:
[root@xxx~]# grep huge /proc/*/numa_maps 2>/dev/null
/proc/47173/numa_maps:140000000 default file=/anon_hugepage\040(deleted) huge anon=1 dirty=1 N0=1 kernelpagesize_kB=1048576
/proc/47173/numa_maps:1000000000 default file=/buffers-numa-0 huge dirty=313 N0=313 kernelpagesize_kB=2048
/proc/47173/numa_maps:1027200000 default file=/buffers-numa-1 huge dirty=313 N1=313 kernelpagesize_kB=2048
/proc/47173/numa_maps:2d00000000 default file=/anon_hugepage\040(deleted) huge anon=1 dirty=1 N1=1 kernelpagesize_kB=1048576
/proc/47173/numa_maps:4dc0200000 default file=/anon_hugepage\040(deleted) huge anon=1 dirty=1 N0=1 kernelpagesize_kB=2048
/proc/47173/numa_maps:4dc0400000 default file=/anon_hugepage\040(deleted) huge anon=1 dirty=1 N0=1 kernelpagesize_kB=2048
/proc/47173/numa_maps:4dc0600000 default file=/anon_hugepage\040(deleted) huge anon=1 dirty=1 N0=1 kernelpagesize_kB=2048
/proc/47173/numa_maps:2aaac0000000 default file=/mnt/hugepages1G/libvirt/qemu/2-instance-0000001f/qemu_back_mem._objects_ram-node0.su05tD\040(deleted) huge dirty=2 mapmax=2 N0=2 kernelpagesize_kB=1048576
/proc/488519/numa_maps:7f6e80000000 bind:0 file=/mnt/hugepages1G/libvirt/qemu/2-instance-0000001f/qemu_back_mem._objects_ram-node0.su05tD\040(deleted) huge dirty=2 mapmax=2 N0=2 kernelpagesize_kB=1048576

SCRIPT
==========

Code:
#!/bin/bash

total_num_hugepages=0

for id in $(grep huge /proc/*/numa_maps 2>/dev/null | awk -F'/' '{proc[$3]=1} END {for (i in proc) print i}'); do
        for hugepagesize in $(find /sys/devices/system/node/node[0-9]*/hugepages/ -type d -name "hugepages-*" | sed 's/.*hugepages-\([0-9]\+\).*/\1/'| sort | uniq);
        do
        ps $id;
        total_num_hugepages+=$(grep huge /proc/$id/numa_maps 2>/dev/null | grep "kernelpagesize.*=$hugepagesize" | sed 's/.*dirty=\([0-9]\+\).*/\1/')
        echo $total_num_hugepages
        done
done

Code:
[root@xxx ~]# ./hugepage_usage.sh
    PID TTY      STAT   TIME COMMAND
  47173 ?        SLl  333416:10 /usr/bin/vpp -c /etc/vpp/vpp.conf
01 1 2
    PID TTY      STAT   TIME COMMAND
  47173 ?        SLl  333416:10 /usr/bin/vpp -c /etc/vpp/vpp.conf
01 1 2313 313 1 1 1
    PID TTY      STAT   TIME COMMAND
 488519 ?        Sl    27:46 /usr/libexec/qemu-kvm -name guest=instance-0000001f,debug-threads=on -S -ob
01 1 2313 313 1 1 12
    PID TTY      STAT   TIME COMMAND
 488519 ?        Sl    27:46 /usr/libexec/qemu-kvm -name guest=instance-0000001f,debug-threads=on -S -ob
01 1 2313 313 1 1 12

Expected sample output
======================
PID TTY STAT TIME COMMAND
47173 ? SLl 333416:10 /usr/bin/vpp -c /etc/vpp/vpp.conf

/usr/bin/vpp
10 hugepages x 1048576 kB = xx kB
2 hugepages x 2048 kB = xx kB
Total hugepage usage = xx kB

Please give me some pointers on how I can improve my code, and achieve the output.

Thanks.

NAME
grep, g - search a file for a pattern SYNOPSIS
grep [ option ... ] pattern [ file ... ] g [ option ... ] pattern [ file ... ] DESCRIPTION
Grep searches the input files (standard input default) for lines that match the pattern, a regular expression as defined in regexp(7) with the addition of a newline character as an alternative (substitute for |) with lowest precedence. Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output. The options are -c Print only a count of matching lines. -h Do not print file name tags (headers) with output lines. -e The following argument is taken as a pattern. This option makes it easy to specify patterns that might confuse argument parsing, such as -n. -i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre- tation. Matched lines are printed in their original form. -l (ell) Print the names of files with selected lines; don't print the lines. -L Print the names of files with no selected lines; the converse of -l. -n Mark each printed line with its line number counted in its file. -s Produce no output, but return status. -v Reverse: print lines that do not match the pattern. -f The pattern argument is the name of a file containing regular expressions one per line. -b Don't buffer the output: write each output line as soon as it is discovered. Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name argument.) Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in single quotes '...'. An expression starting with '*' will treat the rest of the expression as literal characters. G invokes grep with -n and forces tagging of output lines by file name. If no files are listed, it searches all files matching *.C *.b *.c *.h *.m *.cc *.java *.cgi *.pl *.py *.tex *.ms SOURCE
/src/cmd/grep /bin/g SEE ALSO
ed(1), awk(1), sed(1), sam(1), regexp(7) DIAGNOSTICS
Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs. GREP(1)
