  * [[java:9|Java 9]] 에서 추가된 Java Shell

===== shebang =====
  * ''#!'' 형태로 jshell 실행하기
  * [[https://gist.github.com/ffissore/012d7e32a096fde5266f49038c93dcaf|with jshell-wrapper you get runnable java scripts: it removes the heading shebang, adds an "/exit" for good measure, and passes the result to jshell]]

<code sh>
# 이 내용을 jshell-wrapper로 저장하고 #!/path/to/jshell-wrapper 로 shebang 지정
TMP=`mktemp`
tail -n +2 $@ >> $TMP
echo "/exit" >> $TMP
#$JAVA_HOME/bin/jshell -q --execution local $TMP
/usr/bin/env jshell -q --execution local $TMP
rm $TMP

#put this file in /usr/local/bin/ or somewhere in your $PATH
