Help me to find out the problem here [msfconsole]

[madper]

When i run msfconsole directly from my home directory, which run /usr/local/bin/msfconsole everything goes fine except i can't use several standard shell command like 'clear', msf always replay with an error indicating unrecognized the command. This problem not occur when i run msfconsole from /opt/framework/msf3 directory.

the only different is at the first msfconsole there is more path in $PATH, but i think as long as /usr/bin there, command clear should work.

So, where is exactly the problem is?

Thx in advance.

I was experience the exactly some problem with metasploit installed in my ubuntu 11.04 x86 on my netbook. Still have no idea whats going wrong here...

Yes, I also have this same issue (running BT5 on 32-bit gnome). Thus far, it hasn't been a big problem for me, so I've just been ignoring it. I did a global find on clear, and located 2: /usr/bin/clear, and /opt/framework3/bin/clear. When I start msfconsole from the menu, it runs the following: sh -c "msfconsole;sudo -s". I think that how metasploit is started determines how/if shell commands work inside msfconsole.

[scottm99]

A quick follow up...just ran /opt/framework3/bin/clear from a command prompt, and got the message "xterm: unknown terminal type". I think what's happening is a path issue; /opt/framework3/bin/clear is being run, rather that /usr/bin/clear.

You could probably fix this by renaming /opt/framework3/bin/clear. Then, run clear inside of msfconsole, and see what happens

Yeah I can confirm this works on BT-GNOME 32bit.

rm /opt/framework/bin/clear
ln -s /usr/bin/clear /opt/framework/bin/clear

or you could just do rm /opt/framework/bin/clear and then forget about the symlink and msfconsole will find clear all on its own
