Various apps not working in RPi 1B headless

[DanielH]

I've installed TCL in a RPi headless, and installed some apps used to download and share files (curl, wget, lftp, python3.8-pip and then youtube-dl).

I've installed mc too.
mc refuses to start, presenting a message:  aterm: can't open display :0
I can't solve this issue, nor installing aterm.tcz.
How can I solve this problem? Below, my console commands:

tc@cultura:~/Shared$ tce-run mc
tc@cultura:~/Shared$ aterm: can't open display :0

tc@cultura:~/Shared$ tce-size aterm.tcz
  aterm.tcz                                     65536,   0.06 MB
  libICE.tcz                                    36864,   0.04 MB
  libSM.tcz                                     12288,   0.01 MB
  libX11.tcz                                   917504,   0.88 MB
  libXau.tcz                                     4096,   0.00 MB

tc@cultura:~/Shared$
tc@cultura:~$ tce-run aterm.tcz
aterm: can't open display :0

Your answers will be appreciated!
Best regards, DanielH

If you are headless, how do you expect to open a display?  You need to run applications designed for just a shell session.

just type mc on the command prompt to run mc.

@Paul_123

Thanks you! I've erroneously suppose that the mc command needs to be prepended by tce-run.
My mistake!

From TCL wiki:
Start an Application
To start an application that is not loaded, use tce-run app_name
