Sintaxe error, please help

Hey guys, can you please help me.
When I try to come back to vagrant ssh after pulling the linux files, I get the sintaxe error below:

Vagrant failed to initialize at a very early stage:
There is a syntax error in the following Vagrantfile. The syntax error
message is reproduced below for convenience:
m040-vagrant-env-/Vagrantfile:23: syntax error, unexpected ‘~’, expecting keyword_do or ‘{’ or ‘(’
mongod -f ~/university/m040/shared/rs1_li
Documents/m040-vagrant-env-/Vagrantfile:23: syntax error, unexpected tINTEGER, expecting end-of-input
mongod -f ~/university/m040/shared/rs1_linux.conf

do you know how to fix it?

Looks to be issue with vagrant config file
Is any end missing in the block?
Try to give full path of rs1_linux.conf
mongod -f ~/university/m040/shared/rs1_li
