I installed ubuntu from the minimalcd because I just want to use vim and command line tools.
However I would like more than 80 columns of text. I have a large monitor so I would like at least a couple hundred columns so I can split panes in vim and have several windows open.
BTW ubuntu is installed as a VMWare Player VM. I have already verified that the VM settings are for a large monitor; it seems that my ubuntu setup is at issue.
The following command:
docker exec -e COLUMNS="`tput cols`" -e LINES="`tput lines`" -ti container bash
works under most, if not all circumstances.
The variable $COLUMNS specifies how wide the terminal session is; so running COLUMNS=200 would make it 200 columns wide.
If you wanted to change that permanently you should put this in your ~/.bashrc file which is run every time you start a terminal.
I met about the same situation and the above answer was just what I was needed.
But in your case, here are some hints if you are still interested:
Execute: echo $COLUMNS. In my case is was 141.
By manipulating with export COLUMNS=XXX I was indeed been able to adjust the columns amount.
And this 141 number comes from the next.
My .bashrc file contains the next code:
# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize
I don't know for sure, but pretty much seems like using shopt command Ubuntu detects my screen resolution and sets the according number of terminal columns.
Again, setting export COLUMNS=XXX allows me to change this number for the current terminal window.
So in your particular case, you would have to add export COLUMNS=200 after the quoted shopt -s checkwinsize or at the very end of .bashrc.
