attach process to gdb through script

monu_1 — Thu, 21 Jan 2010 17:08:13 GMT

Hello All,

I have a requirement to attach a process to gdb with help of its name in gdb prompt.

I made a script test whose content is :-

Test_script :-:>
VAR=`pgrep '
gdb

and requirement is to attach the process-id in VAR variable to gdb

.gdbinit
attach VAR

The script has to be automated and has to collect many gdb related logs about the process stack and registers periodically with different process name.

Hello.

You can do this like so:

gdb -p "$VAR"

Put commands in ".gdbinit" or in a different file that you pass to gdb with "-x". I recommend to put this in ".gdbinit":

set paginatin off

Then put the rest in another file and call:

gdb -batch -x "myfile" -p "$VAR" > myoutput

You can also set where gdb logs its output inside gdb if you wish.

Goran
