Mac Compatibility Issue For 'expr substr' #76

Closed Hughshine closed 4 years ago

Hughshine commented 4 years ago

grade.sh uses expr substr to cut string, which cannot be use in macos. This problem exists from lab5 to lab8 (also in the corresponding lab_result folder), which can be solved by change one line into this

# example code in lab5, grade.sh, line 256
select=`echo $1 | cut -c 2-${#1}`

Just a notice :-) .
