Documents:
1.Didn’t find any bugs. :)
2.I compare my nsh with /bin/sh when running my test_script and the
output is the same, except the current running process when I run ps
aux.
3. In my test_script, first I printed the section that I am currently testing
first.
Then for each commend, I printed the command/description first, then
executed them. So it will be easier to read the output of my test_script.
(there are new lines in between each commands and sections.)
Notes:
1. I redirect my output result of my test_script to different directory
and delete the testing directory —dir, so when I ls in sh and nsh
will be the same. Or the second one I run will print the previous
one’s output result.
2. /bin/sh test_script > ../sh_res
and
nsh test_script > ../nsh_res
needs to run at the same directory to be able to have the same result,
when I am testing, I put cd /home/lizhenl/cs146/hw6 in the end of my
script, so it can guarantee the ls will give same result. But due to I
don’t know the hierarchy of the testing environment, so i commented
the command out. So when running my test_script please make sure
they run at the same directory.

How to run the shell:
make clean (optional)
make
nsh
?enter commands here (support ;)
?Ctrl +D to terminate
/bin/sh test_script > ../sh_res
Please cd back to the original directory, because right
now you will be at HOME directory
nsh test_script > ../nsh_res
diff ../sh_res ../nsh_res > diff_res
cat diff_res
Note: there should some differences, like the current
running process, the folder’s creation time.
