Note that "==" is a bashism. "=" is more portable across other shells
such as dash.

thank you, the:

if ! [ "${PWD##*/}" == "asdf" ]; then echo "error: not the asdf dir"; exit 1; fi

worked! :)

Two mistakes :
1) "if" expects a command, not a boolean expression. Use "test
" or "[  ]" to evaluate the expression.
2) "-eq" is the equal operator for numeric integers, not strings. Use
"=" for string comparison.

if [ "${PWD##*/}" == "asdf" ]; then echo "this is the asdf folder"; else exit 
1; fi


Why not simple use:

if [ -e $SCRIPT ]; then
  echo "File exists";
else
  echo "File does not exist";
fi
