stdout

问题 I'm looking to use a personal RSS Feed for system reporting, so I'm wondering if it's possible to create a script that sends its $1 to an RSS feed, ala self_test_command > rss_report.sh . I don't currently have an RSS feed set up, either, so what would be the easiest way to set up an RSS feed running from a Linux box? 回答1: I have a proper solution for you, in command line . That use Perl Template::Toolkit module in background (no need to learn Perl just now) : first install the package perl

问题 I ran into something different today. Consider this simple function: def hi(): return 'hi' If I call it in a Python shell, >>> hi() 'hi' >>> print hi() hi It prints out the 'returned' value, even if it's just the repr . This felt odd to me, how could returning be printing to stdout? So I changed it to a script to be run: def hi(): return 'hi' hi() I ran this from terminal: Last login: Mon Jun 1 23:21:25 on ttys000 imac:~ zinedine$ cd documents imac:documents zinedine$ python hello.py imac

问题 What I'm trying to do is launch the C program executable inside the Java application and allow them to communicate with each other using stdin and stdout. The C program will wait for a command from the java app and echo it back. I've tested the java code with "gnugo --mode gtp" (gnugo with in gtp mode communicates with stdin and stdout) and it works fine but my doesn't work with my C code. Any suggestion would greatly appreciated. C code #include <stdio.h> #include <stdlib.h> #include <string

问题 First question, ahhhh! Does anyone know / have info about why mongoose writes its debug log to stderr? Is there anyway to write it to stdout? 回答1: The debug option accepts a function instead of a boolean: mongoose.set("debug", function (collection, method, paramA, paramB, paramC) { console.log(collection) console.log(method) console.log(paramA) console.log(paramB) console.log(paramC) }) The reason I put paramA, paramB, paramC is because the arguments are dependent upon the method and options

问题 I wanna redirect cmd.exe output somewhere, below code works when the command is a line: Process p = new Process() { StartInfo = new ProcessStartInfo("cmd") { UseShellExecute = false, RedirectStandardInput = true, RedirectStandardOutput = true, CreateNoWindow = true, Arguments = String.Format("/c \"{0}\"", command), } }; p.OutputDataReceived += (s, e) => Messagebox.Show(e.Data); p.Start(); p.BeginOutputReadLine(); p.WaitForExit(); But how about a series commands like WriteLine(): p

问题 I have the following request library(RCurl) res=getURL("http://www.google.com/search?hl=en&lr=&ie=ISO-8859-1&q=RCurl&btnG=Search", .opts=list(verbose = TRUE) ) and would like to capture the verbose output of the call (i.e., what is printed in red in the R console). I thought that the output lines are messages and are therefore printed to stderr() . The following works for messages sink(textConnection("test","w"),type="message") message("test message") sink(stderr(),type="message") test #[1]

问题 This question already has answers here : Perl: Print on the “display” and also into a file (4 answers) Closed 6 years ago . I have a Perl script with several print statements. Is there a way by which I can direct all of these print statements to a file as well as to stdout simultaneously without duplicating print statements ? 回答1: You can use File::Tee. use File::Tee qw(tee); tee STDOUT, '>>', 'some_file.out'; print "w00p w00p"; If File::Tee is unavailable, it is easily simulated with a

问题 In shell script, We can change the default input to a File using the exec command as follow : exec 1>outputfile However, if in the same script if I want to restore the stdout descriptor '1' to the default (terminal). How can we achieve that? 回答1: This example Example 20-2. Redirecting stdout using exec #!/bin/bash # reassign-stdout.sh LOGFILE=logfile.txt exec 6>&1 # Link file descriptor #6 with stdout. # Saves stdout. exec > $LOGFILE # stdout replaced with file "logfile.txt". # --------------

问题 I want to meassure the throughput of a link using Windows build-in FTP tool inside a Perl script. Therefore the script creates the following command script: open <ip> <username> <password> hash get 500k.txt quit Afterwards I run the command script using the following Perl code: system(@args); @args = ("ftp", "-s:c:\\ftp_dl.txt"); system(@args); If I run the command inside a DOS-box the output looks like this: ftp> open <ip> Connected to <ip> 220 "Welcome to the fast and fabulous DUFTP005 ftp

问题 This question already has answers here : How to just call a command and not get its output [duplicate] (4 answers) Closed last year . For the following command: subprocess.call(shlex.split( """/usr/local/itms/bin/iTMSTransporter -m lookupMetadata -apple_id %s -destination %s"""%(self.apple_id, self.destination)) It prints the entire output into the Terminal window. How would I suppress ALL output here? I tried doing subprocess.call(shlex.split(<command> > /dev/null 2&1 )), but it didn't
