My actual problem is that a process I run in an rcfile in docker as docker run container bash --rcfile rcfile remains attached to the bash session by sharing the PGID which means that when I Ctrl-C an unrelated command the process receives a SIGINT
So, inside the rcfile its just (nohup command &), when instead of using the rcfile I call it directly in the shell the PGID is different and Ctrl-C does not affect.
From there I deduced that for some reason, bash does not background processes the same while executing the rcfile.
Wrote a small test without docker where I see the PGID behavior.
RCFILE, sleep and bash share PGID
Cobain ~/tmp/testbash$ cat rcfile
#!/bin/bash
(sleep 10 &)
Cobain ~/tmp/testbash$ bash --rcfile rcfile
arkaitzj@Cobain:~/tmp/testbash$ ps -o "%p %r %y %x %c"
PID PGID TTY TIME COMMAND
2883 2883 pts/0 00:00:06 bash
27911 27911 pts/0 00:00:00 bash
27913 27911 pts/0 00:00:00 sleep
27914 27914 pts/0 00:00:00 ps
Command input in the shell, PGID differs
Cobain ~/tmp/testbash$ bash
Cobain ~/tmp/testbash$ ( sleep 10 &)
Cobain ~/tmp/testbash$ ps -o "%p %r %y %x %c"
PID PGID TTY TIME COMMAND
2883 2883 pts/0 00:00:06 bash
27999 27999 pts/0 00:00:00 bash
28127 28126 pts/0 00:00:00 sleep
28132 28132 pts/0 00:00:00 ps
What I don't understand of this bash example though, is that in the rcfile case, when I ctrl-C it does not SIGINT the sleep process, when it is sharing the PGID
