== Print Global variable ==
In gdb
"info variables" list all global and static variable names
Could also check "info locals" which list local variables of current stack frame or "info adress <symbol>"

to save all globals in a file (my_global_var)
./gdb myprog
set logging file my_global_var
set logging on
info variables
set logging off
q

prepare a file with gdb commands to print every variables except pointer
#!/bin/sh
rm command_gdb;
echo "set print array on" >>command_gdb;
echo "set print pretty on" >> command_gdb;
echo "set logging on" >> command_gdb ;
for i in $(more my_global_var | grep -v ":" | grep -v "*" | awk ' { print ( $(NF) ) }'| awk -F";" '{print $1}'| sed 's/$[.^[]*$\[.*\]/\1/); do echo "print $i" >> command_gdb; done

prepare a file with gdb commands to print every var
#!/bin/sh
rm command_gdb_pt;
echo "set print array on" >>command_gdb_pt;
echo "set print pretty on" >> command_gdb_pt;
echo "set logging on" >> command_gdb_pt ;
for i in $(more global_var_isp | grep -v ":" | grep "*" | awk ' { print ( $(NF) ) }'|sed 's/\*$.*$;/\1/'| sed 's/$[.^[]*$\[.*\]/\1/); do echo "print $i" >> command_gdb_pt; done

get variables values
gdb ./myprog
b init_func
r
#break 1
set logging file var_before
source -v command_gdb
set logging file off
c
#Do stuff
#break
set logging file var_after
source -v command_gdb
set logging file off
