syntax error near unexpected token `(' in below code

Question

I have very small shell script.When I am running it run flow. it is giving "syntax error near unexpected token `(". Very basic question but sorry not able to figure out.

foreach i ( `cat list407`)
mkdir cells/${i}
 cp /<path>/$i/${i}.gds cells/${i}/${i}.gds
end

Error:

flow: line 1: syntax error near unexpected token `('
flow: line 1: `foreach i ( `cat list407`)'

You seem to be executing csh syntax using bash.

You've used csh syntax for execution using bash which is causing the error.

Either use csh to execute your script, or using bash say:

while read -r i; do
  mkdir "cells/${i}"
  cp "/<path>/${i}/${i}.gds" "cells/${i}/${i}.gds"
done < list407

for i in $(cat list407); do
  mkdir cells/${i};
  cp /<path>/$i/${i}.gds cells/${i}/${i}.gds;
done

Bad practice. Never use command substitution with for loop. Also, never read a file with for loop, always use while for this purpose. refer this
