Re: [Help-bash] How to figure out what files has been loaded by bash?

[Eduardo A . Bustamante López]

You can also run:

ssh -t ... 'bash --norc --noprofile -i'

(or ssh -t ... 'bash --norc --noprofile -l', since IIRC ssh spawns a login
shell)

So that it doesn't load any file. And then you can debug it inside the remote
host.

It might also be a good idea to strace it, if using GNU/Linux:

| address@hidden ~ % ssh -t HOST 'strace -o /tmp/s -e open bash -i' 
| address@hidden ~]$ exit
| Connection to HOST closed.
| address@hidden ~ % ssh HOST 'cat /tmp/s'
| open("/etc/ld.so.cache", O_RDONLY)      = 3
| open("/lib/x86_64-linux-gnu/libtinfo.so.5", O_RDONLY) = 3
| open("/lib/x86_64-linux-gnu/libdl.so.2", O_RDONLY) = 3
| open("/lib/x86_64-linux-gnu/libc.so.6", O_RDONLY) = 3
| open("/dev/tty", O_RDWR|O_NONBLOCK)     = 3
| open("/usr/lib/locale/locale-archive", O_RDONLY) = 3
| open("/proc/meminfo", O_RDONLY)         = 3
| open("/etc/nsswitch.conf", O_RDONLY)    = 3
| open("/etc/ld.so.cache", O_RDONLY)      = 3
| open("/lib/x86_64-linux-gnu/libnss_compat.so.2", O_RDONLY) = 3
| open("/lib/x86_64-linux-gnu/libnsl.so.1", O_RDONLY) = 3

| open("/etc/passwd", O_RDONLY|O_CLOEXEC) = 3
| open("/usr/lib/x86_64-linux-gnu/gconv/gconv-modules.cache", O_RDONLY) = 3
| open("/etc/bash.bashrc", O_RDONLY)      = -1 ENOENT (No such file or 
directory)
| open("/home/dualbus/.bashrc", O_RDONLY) = 3
| open("/home/dualbus/.bash_history", O_RDONLY) = 3
| open("/home/dualbus/.bash_history", O_RDONLY) = 3
| open("/lib/terminfo/r/rxvt-unicode", O_RDONLY) = 3
| open("/etc/inputrc", O_RDONLY)          = 3

vs:

| address@hidden ~ % ssh -t HOST 'strace -o /tmp/s -e open bash --norc 
--noprofile -i'
| bash-4.2$ exit
| Connection to HOST closed.
| address@hidden ~ % ssh HOST 'cat /tmp/s'
