How to use shell scripts in node

touch newFile.sh

chmod 777 newFile.sh changes the file to be readable, writable and executable

//Use the file reading method in the child process of nodejs const { execFile } = require('child_process');

DocsService.publishAllDocs = (req, res) => {

 var fileArr, fileName, spath, dirnameBack, docbackList = [], docbackPath, docPath = "";
 var username = req.session.user_name;
 var str = docName+'/'+ pathName + '|'+ username;
 var reg = new RegExp(`^(${str})`);

   }

   docbackPath = path.join(__dirname, dirnameBack);
   docbackList.push(docbackPath);
   docPath += docbackPath + " ";

 docPath += ""
 //cwd sets the current path. What I set here is the current location of the nodejs code js execFile(filepath, [docName, docPath, docType], { cwd: '.' }, function(err, stdout, stderr){

## $2 is the data received in the script and spliced ​​in the format as shown in the data example above## Use for...in in a loop. Remember to add do after it to execute the loop body and end the loop with done## Each sub-item of the item loop body is as follows: /Users/Desktop/work/docManager/docServer/gitlib/docBackup/mygitbook/docs/d09985fc67088b35/d09985fc67088b35.md
