如何检查目录中除 Groovy 语言中的一个文件之外的所有文件

Question

I am trying to search a word in every file in a directory but I want to exclude my logfile.

My code is something like this

user input: search test C:\Users\Desktop\test\Groovy

My code

import static groovy.io.FileType.FILES
import java.text.SimpleDateFormat

def terminal_log = new File("terminal.log")
def terminal_log_path = terminal_log.getName()
def fas = ""
def file2_path = ""
def cmd = System.console().readLine 'Enter command: '
String[] csplice = cmd.split(" ");
if(csplice.length == 3){
    def first_parameter = csplice[0]
    def second_parameter = csplice[1]
    def third_parameter = csplice[2]
    if(first_parameter == "search"){
        def file = new File(third_parameter)
        if(file.exists()){
            if(file.isDirectory()){
                file.eachFile(FILES) { f -> 
                    fas = "/"+f+"/"
                    File file2 = new File(fas)
                    file2_path = file2.getName()
                    if(!file2_path == terminal_log_path){
                        file2.eachLine{ line ->
                            if(line.contains(second_parameter)){
                                println "This file contains this word"
                            }
                        }
                    }
                }
            }else{
                println "Not a directory"
            }
        }else{
            println "Not exists"
        }
    }else{
        println "Invalid command"
    }
}else{
    println "Invalid command"
}

This block here is not working

if(!file2_path == terminal_log_path){

Is there any documentation that I can read to exclude a specific file while checking every files in a directory?

Many thanks

EDIT: the directory of the user input has the logfile (terminal.log) terminal.log exists

It should be:

if (file2_path != terminal_log_path) {
   ...
}

or

if (!(file2_path == terminal_log_path)) {
   ...
}

Eg you can run the following code to see the result of applying the "Not" operator to a string in Groovy:

def file2_path = "/i/am/path/"
println (!file2_path) // prints false file2_path is not an empty string

For more info, you can refer to the official Groovy doc on that topic:

The "not" operator is represented with an exclamation mark (.) and inverts the result of the underlying boolean expression, In particular: it is possible to combine the not operator with the Groovy truth:

    assert (!true)    == false
    assert (!'foo')   == false
    assert (!'')      == true
