queryp

a nodejs package for process query

usage

queryp( filter, callback )

example:
queryp({command:"chrome"}, (err, procs)=>{
        if( err ){
            console.error(err)
            return
        }
        procs.forEach((proc)=>{
            console.log( `${proc.pid} ${proc.command}` )
        })
})

filter

filter of queryp only support four field for filtering:
pid/ppid/command/cmd
you could specify filter like 
{
    pid : 123
} 
to find all processes with pid that match /123/
or 
{
    cmd : "node.*_mocha"
}
to find all processes with command line that match /node.*_mocha/
or
{
    ppid : 123
}
to find all processes with ppid that match /123/, which means it may also return processes with ppid 1234, but you could use array.filter to filter that out

it should noted that the filter support nodejs regex

return procs

Each item of procs should contain four keys:

• pid : pid of process
• pid : parent pid of process
• command : command name of process,for example, node
• cmd : command line of process, for example, node index.js

Attention

if you run queryp in linux, what you may get like cmd could be truncate, I will try to fix this later
