I receive

syntax error: unexpected end of file

when trying to execute a script. What’s wrong with the script? (checked in https://www.shellcheck.net/ like everything is green)

#! / bin / sh
PROCESS_COUNT = $ (ps aux | grep my-program | grep -v grep | awk '{print $ 2}' | wc -l)
if [$ PROCESS_COUNT! = 0]; then
  ps aux | grep my-program | grep -v grep | awk '{print $ 2}' | xargs kill -9
fi
FINAL_RESULT = $ (ps aux | grep my-program | grep -v grep | awk '{print $ 2}' | wc -l)
if [$ FINAL_RESULT! = 0]; then
  echo "error thrown"
fi

Answer 2, authority 100%

Instead of counting the number of processes as insurance against calling kill without arguments, it is much more convenient to use the while read loop, because if there are no items in the process list, it simply will not start. For example:

#! / bin / bash
my_program = sublime_text # for example
while read -r pid
do
  kill -9 "$ {pid}"
done & lt; & lt; (awk '$ 11 ~ my_program {print $ 2}' my_program = "$ {my_program}" & lt; & lt; (ps aux))
