使用telnet在QNX提示符下执行二进制文件时确定等待时间

Question

I am processing certain output binary files using sloginfo on QNX, I have used ftp/telnet/vmware to get to a point where I upload the binary from my machine to the vmware instance and then run the sloginfo command. The issue is that binary files which need to be processed are of inconsistent size (ranging from 50mb to 200mb), and the time needed to process each of these files is different, thus making it impossible to determine the wait/sleep time required.

I need to know if sloginfo returns a value which can be used as a flag. I tried using tn.read_until(), without getting desired results.

 import os, sys, telnetlib, time from ftplib import FTP def upload(ftp, filed): ext = os.path.splitext(filed)[1] if ext in (".txt", ".htm", ".html"): ftp.storlines("STOR " + filed, open(filed)) else: ftp.storbinary("STOR " + filed, open(filed, "rb"), 1024) def gettext(ftp, filename, outfile=None): # fetch a text file if outfile is None: outfile = sys.stdout # use a lambda to add newlines to the lines read from the server ftp.retrlines("RETR " + filename, lambda s, w=outfile.write: w(s+"\\n")) if __name__ == '__main__': dbfile = "LOG1" nonpassive = False remotesite = '192.168.0.128' ftp_port = '21' tel_port = '23' password = 'root' ftp = FTP() ftp.connect(remotesite, ftp_port) ftp.login('root','root') print 'Uploading the Log file... Please wait...' upload (ftp, dbfile) print 'File Uploaded Successfully...' tn = telnetlib.Telnet(remotesite, tel_port) tn.read_until("login: ") tn.write('root' + "\\n") if password: tn.write(password + "\\n") tn.write("sloginfo LOG1 >> LOG1.txt\\n") **#need to get more control on this sleep time** time.sleep(300) print 'Downloading text file...' gettext(ftp, "LOG1.txt", open(r'LOG1.txt','wb')) ftp.close() tn.close() 

Answer 1

tn.write（“ sloginfo LOG1 >> LOG1.txt \\ n”）使用tn.write（'sloginfo'+ strdbfile +'>>'+ strdbfiletxt +'; echo Done！\\ n'）修改了以上注释，并且已解决问题
