我正在编译
Scala代码并在文件中写出输出控制台输出.我只想在文件中保存STDOUT的最后一行.这是命令：
scalac -Xplugin:divbyzero.jar Example.scala >> output.txt
scalac -Xplugin：divbyzero.jar Example.scala的输出是：
helex@mg:~/git-repositories/my_plugin$scalac -Xplugin:divbyzero.jar Example.scala | tee -a output.txt You have overwritten the standard meaning Literal:() rhs type: Int(1) Constant Type: Constant(1) We have a literal constant List(localhost.Low) Constant Type: Constant(1) Literal:1 rhs type: Int(2) Constant Type: Constant(2) We have a literal constant List(localhost.High) Constant Type: Constant(2) Literal:2 rhs type: Boolean(true) Constant Type: Constant(true) We have a literal constant List(localhost.High) Constant Type: Constant(true) Literal:true LEVEL: H LEVEL: H okay LEVEL: H okay false symboltable: Map(a -> 219 | Int | object TestIfConditionWithElseAccept2 | normalTermination | L,c -> 221 | Boolean | object TestIfConditionWithElseAccept2 | normalTermination | H,b -> 220 | Int | object TestIfConditionWithElseAccept2 | normalTermination | H) pc: Set(L,H)
只需将stdout通过tail -n 1传递给你的文件
