Is Midnight Commander stability

[tbvink]

Hi,

I am new to TrueNAS Core and have installed TrueNAS-13.0-U2 on a PC with a Gen 12 I5 CPU.

For much of the file maintenance I expect to do, MC looks like a wonderful solution. However it crashes so easily I am wondering if it is supported in the latest versions of TrueNAS. For example:

If I start MC from the directory that the shell starts in, it prints half of a screen and crashes. Will not respond to any keys. If I CD up a level MC runs OK.

On the F6 command ( copy/move ) I am not sure how to select the two files but when I press F6, MC crashes. I was able to move a directory yesterday, but to my recollection the same procedure crashes today.

I have started reading the documentation for MC but as I try things, a lot does not seem to work.

If MC is a recommended service, I can provide more detail to my problems.

Thanks,
Tony

MC should work and be stable. If it's crashing, the best thing to do is likely to submit a bug report through the TrueNAS GUI, attaching a debug file and screen shots of any of the crash messages.

I am not sure how to select the two files

Ctrl-T will "tag" or select a file, repeat for as many files as you like.

Are you using the shell in the web UI? Don't. That one is broken. Use Putty or Windows 10+ native or Mac OS SSH to connect directly, Then use mc in that terminal window.

Thanks, I'll give it a try.

I am using MC in the GUI shell. So I'll try the putty terminal to see if that works better. ( Patrics advice )

Hi,

In putty I logged in as my user name. Then "cd /" to go to the root directory.
When I run mc, I get the following:

common.c: unimplemented subshell type 1
read (subshell_pty...): No such file or directory (2)
truenas%

So I guess I either do not have my user setup properly in TrueNAS or I need to do some shell configuration. I dont need to install MC, do I?

Thanks again,
Tony

I use MC a lot but only as root. My guess would be that the account's home directory or login shell setting is causing this.

I have root access as well as my standard Active Directory user on our TrueNAS and I get exactly the same error when logging in as an unprivileged user:

Code:

ry93@truenas:~ $ mc
common.c: unimplemented subshell type 1
read (subshell_pty...): No such file or directory (2)

The solution seems to be to run mc -u:

misc/mc problem

For a week or a couple of weeks, after upgrade of misc/mc port, I can't start mc from ordinary user, only from root. I tried doing it from different shells. The error states:common.c: unimplemented subshell type 1 read (subshell_pty...): No error: 0 (0) May be something wrong was during upgrade...

No, it's installed for you. Based on the thread Patrick linked (which I also had found), there are two possible fixes:

• invoke mc with the -u flag, or
• change the user's shell to bash, tcsh, or zsh.

The latter can be done in Accounts -> Users, edit the user in question and change the shell there.

Thanks, mc -u did it!
