Hi all, I am new to the forum and Shell Script programming.
The problem is:
I need to do a script to search all system processes and show me hierarchical way the number of bytes occupied by each of the regions of the memory map of each process.
Today I got to show me the number of regions in the memory map, this I did just to check if it really is working on AWK, now I have not done is stored in 2 variables memory addresses that appear in the first chain MAPS each line of the file, I understand that the address is in hexadecimal format must subtract the address "minor" to "higher" but first change the string to uppercase divided into two variables (that I understand) and then perform the calculation for show me now if I need hehe happy Bytes
Here the public part of the file MAPS:
00110000-00126000 r-xp 00000000 08:01 8051 /usr/lib/libnssutil3.so
00126000-00129000 r--p 00015000 08:01 8051 /usr/lib/libnssutil3.so
00129000-0012a000 rw-p 00018000 08:01 8051 /usr/lib/libnssutil3.so
0012a000-0012d000 r-xp 00000000 08:01 7711 /usr/lib/libgmodule-2.0.so.0.2200.2

The script is as follows:
#!/bin/sh
#!/bin/bash
filtrado()

thank you very much guys
