can't not open source_file

[ZZZ02zk]

I am stuck at task1 step 4, the system report that they can't not open the source file. but the source file works fine at Lab 0, I don't know how to fix it.

Hi, this is because currently you are in the Lab1 directory, you will need to cd into task1's directory, where your files are.
cd task1
and then running the commands should work
