Unable to create a directory using mkdir

I installed Openfoam a couple of days ago . I could follow the instructions given here without facing any major issues. However, when I run the command $mkdir -p $FOAM_RUN today, I am getting this error: mkdir: missing operand. I also tried mkdir -p "$FOAM_RUN" (it is suggested here). Even this failed with the error message mkdir: cannot create directory `': No such file or directory. /.bashrc file is updated as per the instructions given on Openfoam website.

Like @unxnut said, your variable is not defined. To define the variable, you just type:

FOAM_RUN=dir_name

then your above command will create a directory called "dir_name", or whatever you assign FOAM_RUN.

Hope this helps.

Seems to me that your variable $FOAM_RUN is not defined. You can confirm that by executing the command: echo $FOAM_RUN
