No such process found!

[rahilwazir]

Following the code:

let childWorker = cp.fork(`${__dirname}/../somefile`);

console.log(childWorker.pid);
// 12345

ps.lookup({ pid: childWorker.pid }, (err, resultList) => {
    console.log(resultList);
    // []
});

Why it didn't work? I also randomly picked pid from ps -A and it still didn't work.

Weird, I am also having this issue. It just doesn't work!

ps.lookup {command: 'node'}, (err,res) ->
  console.log 'ps.lookup', err, res # always null, []

OSX 10.10

[jamietre]

This doesn't work at all for me in Winows either. No processes are ever returned.

I believe issue is with the TableParser.parse method.

On Mac, I run ps and I get:
/Users/bin/ffmpeg-f:v mpegts -fflags nobuffer -probesize 18192 -i udp://8.8.8.8:9000 -ignore_unknown -vf fps=20 /tmp/

However, when running ps.lookup, that process isn't found.

[IstoraMandiri]

@sleman you're correct - it seemed to be a problem with TableParse - it wasn't parsing the PID correctly

@neekey please see neekey/table-parser#3 any comment?

[neekey]

Hi, guys, I'm sure this is caused by neekey/table-parser#3 , I will fix it soon.

[ricovitch]

Does not work for me on windows.
I see @hitchcott made a patch, but i prefer to seek for another solution.

Actually there is this forked version that seems to work : https://www.npmjs.com/package/ps-nodejs

[codeandcats]

Yep TableParse is the issue. It is expecting line endings to be \n when they can be \r (even on windows).

[leegee]

👍

[jamietre]

Or just use sindre sorhus' package which works: https://github.com/sindresorhus/ps-list

I'm all for alternatives, but this code has been broken since I first tried it 6 months ago. You should make a note in the readme that it doesn't work so people don't keep wasting time, until if/when it is fixed.

[codeandcats]

Awesome, thanks for the suggestion @jamietre!

[leegee]

On the table-parser issue page, nfantone commented on 2 Jan this year, ps-node doesn't even need a table parser. Thanks, @jamietre, for your suggestion - I'll try that.

i noticed, i don't get a result when calling with an interger as pid paremeter, but converting it to a string it works just well.

i looked into the code and at

// 若限定了id列表
if( idList && idList.indexOf( String( p.pid ) ) < 0 ){
  return;
}

you are casting p.pid as a string and then matching it with an array that may (and with regards to your sample code should) hold integers. PR is underway.

[yetzt]

ping @neekey.

[yetzt]

well, i sent @neekey an email, but so far no response. i implemented the functionality i needed myself in this module, feel free to use it.

[PaulTerryGameDev]

Does this work for Windows 10 64-bit?

[PaulTerryGameDev]

(It doesn't seem to work for me in Windows 10 64-bit..is not finding any processes by ID (using the first example in the help)

[yetzt]

@PaulTerryGameDev this uses the ps command found on unix operating systems. you could write something that uses tasklist and parse it's output.

[neekey]

Sorry guys! I'm back! I just rewrite table-parser with connected-domain, and I create a new branch of PS using the latest version of table-parser.

The parser problem should be fixed, but I need you to help me test with it, install it through github:

npm install https://github.com/neekey/ps.git#0.1.0

@yetzt your PR is included

@PaulTerryGameDev I haven't got a chance to try win 10, can you open a new issue for it?

[neekey]

Hi guys, I have published version 0.1.0, and I will focus on these two issues( neekey/table-parser#4, #10 ) ,feel free to reopen this issue if you encounter any problem related.

[Luiz-N]

I'm having this issue now with latest version

[neekey]

Hi @Luiz-N, could you please provide more details like:

• your OS version
• NodeJS version
• the code you were running

thank you

[neekey]

@cloudtaxi ps-node has already passed test on Mac and Linux through https://travis-ci.org/neekey/ps, and I tested it with NodeJS 6.1.0 on my Mac, it works. Can you install the latest version of 0.1.1, run its test cases with npm test and tell me the result ?

Thank you

[breezewish]

I have the same issue as @cloudtaxi . npm test are passed.

1. in OS X: ps l will not return a full list of processes.
2. ps aux works, however the columns are incorrectly-mapped, may due to Chinese characters

[breezewish]

It may be much more easy to parse result if you use formatted output as https://github.com/yibn2008/find-process/blob/master/lib/find_process.js#L27

[neekey]

@summerwish if your problem is caused by multiple-byte characters, then it is a know issue with table-parser neekey/table-parser#4

However, the link you provided does not help much as you can see from the manual for ps:

-w      Use 132 columns to display information, instead of the default which is your window size.  If the -w option is specified more than once, ps will use as many columns as necessary without regard for your
             window size.  When output is not to a terminal, an unlimited number of columns are always used.
-o      Display information associated with the space or comma separated list of keywords specified.  Multiple keywords may also be given in the form of more than one -o option.  Keywords may be appended with
             an equals (`=') sign and a string.  This causes the printed header to use the specified string instead of the standard header.  If all keywords have empty header texts, no header line is written.

-w and -o really do not help to solve this problem, and to be honest, I do not have a good idea to deal with it right now. But you can avoid this problem by not using option "u" ( notice not "-u", "u" means to show detailed information, which will include a STARTED field, which may be output as local string ) or "-f" which quite does the same thing.

Another idea I just came out is maybe there's a way I can enforce the PS command to output a specified language like English, but I am not sure if it can be done.

How this can give you a little help : )

[breezewish]

Hi, thanks for your explanation! How about just split each row by whitespace? Since you can use -o to put the arg column as the last column and project only part of the columns, other columns should not contain any whitespace.

[neekey]

@summerwish the situation is much more complicated than you may have thought, for example, for some rows their certain field may be blank, and another case is that for COMMAND filed, they will include space to separate their command and arguments like:

System/Library/Frameworks/CoreServices.framework/Frameworks/Metadata.framework/Versions/A/Support/mdworker -s mdworker -c MDSImporterWorker -m com.apple.mdworker.single

and in windows you may not be able to control the position for COMMAND field, and not even in some case you will encounter strings like below:

"hello world"

Hope this makes sense to you

[breezewish]

Besides, ux breaks this utility in OS X:

ps.lookup({ psargs: 'ux' }, ...);

outputs:

{ pid: 'Breezewish',
    command: 'node',
    arguments: [ 't.js' ],
    ppid: undefined }

which is not correct

[breezewish]

Wow. Windows is a problem that I didn't considered :(

[MikiDavid]

Hi @neekey,

I had this issue now:

Attempt to found an active process by its name: NearoHostServer.exe - Fail each time and got [].
When at command I write nearohostserver.exe - Works like a charm and giving back the details.

My code:
Working:

var ps = require('ps-node');

ps.lookup({
    command: 'nearohostserver.exe',
    arguments: ''   
}, function(error, resultList){
    console.log(resultList);
        // [ { pid: '1104',
        // command: 'c:\\program files (x86)\\mce-100\\nearohostserver.exe',
        // arguments: [ '5F975E550A3FD20DDCA48B38EAF586F2', '/worker' ],
        // ppid: undefined } ]
})

Not Working:

var ps = require('ps-node');

ps.lookup({
    command: 'NearoHostServer.exe',
    arguments: ''   
}, function(error, resultList){
    console.log(resultList);
        // []
})

Windows 10 x64, table-parser version 0.1.1, ps-node version 0.1.1.
On other PCs at my organization, its working with capital letter, only at mine its not working.

[neekey]

@MikiDavid thanks for submiting this bug, it seems like a problem caused by string matching, should be fixed easily.

[neekey]

@MikiDavid I just published 0.1.2, it should fix this bug.
