gdb不执行文件命令

Question

I'd like to execute following commands during gdb start. I've put them in file in my /root directory.

> cat /root/gdbst.gdb
file /root/centos-6.3-x86_64/abc
dir /root/centos-6.3-x86_64/dir/abcdir
target extended-remote 192.168.0.180:1234

Then I run

> gdb -x /root/gdbst.gdb

gdb is started but no command executed.
Here is what I get

root@ubuntu:~# gdb -x /root/gdbst.gdb

(gdb)

And

-rwxrwxr-x  1 root root  236 Jan 24 03:16 gdbst.gdb

Doing so from gdb command prompt

(gdb) source -v /root/gdbst.gdb
+file /root/centos-6.3-x86_64/abc
+dir /root/centos-6.3-x86_64/dir/abcdir
+target extended-remote 192.168.0.180:1234

Runnign all these commands manually do what I want: gdb sets file and dir and connects to remote gdbserver. But why it ignores command file?

Answer 1

Seems that problem was with remote side. gdbserver had been started, but it doesn't respond to connections as it should. So gdb executed commands silently, and last command doesn't connect to remote gdb, but silently. Restarting gdbserver solved the problem. But seems that it should be restarted any time I'd like to reconnect...
