stdout

问题 I'm using PBSPro and am trying to use qsub command line to submit a job but can't seem to get the output and error files to be named how I want them. Currently using: qsub -N ${subjobname_short} \ -o ${path}.o{$PBS_JOBID} -e ${path}.e${PBS_JOBID} ... submission_script.sc Where $path=fulljobname (i.e. more than 15 characters) I'm aware that $PBS_JOBID won't be set until after the job is submitted... Any ideas? Thanks 回答1: The solution I came up with was following the qsub command with a qalter

问题 I start a python script in my java application with Process p = Runtime.getRuntime().exec("python script.py"); This script runs in a loop and is only canceled by an event (or user interaction). The script writes to the output every loop cycle, some text like "12:22:35 -- Heartbeat" while True: print("Heartbeat") time.sleep(1) In my Java application I want to read this output as it appears. My problem is, if I use the BufferReader, it will wait until the process is completed and after that it

问题 So I have a python application that is being bundled into a .app using py2app. I have some debugging print statements in there that would normally print to stdout if I was running the code in the terminal. If I just open the bundled .app, obviously I don't see any of this output. Is any of this actually being printed somewhere even though I don't see it? 回答1: It goes to standard output (so in the command line, if you are opening it in command line, or eg. to the log, if you are running it

问题 Profiling my program and the function print is taking a lot of time to perform. How can I send "raw" byte output directly to stdout instead of using fwrite, and making it faster (need to send all 9bytes in the print() at the same time to the stdout) ? void print(){ unsigned char temp[9]; temp[0] = matrix[0][0]; temp[1] = matrix[0][1]; temp[2] = matrix[0][2]; temp[3] = matrix[1][0]; temp[4] = matrix[1][1]; temp[5] = matrix[1][2]; temp[6] = matrix[2][0]; temp[7] = matrix[2][1]; temp[8] = matrix

问题 I am currently calling a DLL from labview, but I need to be able to debug it realtime (because of it's accessing time sensitive hardware). I would like to just printf() my error assert messages but I am unsure about how to open a DOS window from within the DLL to dump error information to. Has anyone done this before? I know I could do this with a file, and I may have to. printf is just such a handy quick and dirty way to do this though :) . 回答1: 1) Make a call to the windows api AllocConsole

问题 Because of stdin and stdout buffering sometimes printf , scanf and getchar are not executed. I usually flush output buffer using fflush(stdout) but code can become very unreadable because of that. If I set stdin and stdout unbuffered using setbuf(stdin, NULL) and setbuf(stdout, NULL) will I make my program perform better or worse? 回答1: Making stdin or stdout completely unbuffered can make your program perform worse if it handles large quantities of input / output from and to files. Most I/O

问题 How can I connect two C# processes so they can communicate with each other over stdin and stdout? Like this: Process A --> stdout A --> stdin B ---> Process B Process A <-- stdin A <-- stdout B <--- Process B 回答1: using System; using System.Diagnostics; class Program { static void Main(string[] args) { string name; if (args.Length > 0 && args[0] == "slave") { name = "slave"; } else { name = "master"; var info = new ProcessStartInfo(); info.FileName = "BidirConsole.exe"; info.Arguments =

问题 I have a bash script with some scp commands inside. It works very well but, if I try to redirect my stdout with " ./myscript.sh >log ", only my explicit echos are shown in the "log" file. The scp output is missing. if $C_SFTP; then scp -r $C_SFTP_USER@$C_SFTP_HOST:$C_SOURCE "$C_TMPDIR" fi Ok, what should I do now? Thank you 回答1: scp is using interactive terminal in order to print that fancy progress bar. Printing that output to a file does not make sense at all, so scp detects when its output

问题 I have an application in Go that reroutes the STDIN and STDOUT of binaries and then runs them. In a nutshell I'm doing: - create command object with the binary path (lets call the object command A) - create command object with the binary path (calling it command B) - set the stdout of command B to the stdin of Command A - start command A - start command B I noticed whenever the process for command B exits while command A is running, it becomes a zombie process in the process table. Here's an

问题 How can I redirect the STDOUT stream to two files (duplicates) within my Perl script? Currently I am just streaming into a single log file: open(STDOUT, ">$out_file") or die "Can't open $out_file: $!\n"; What do I have to change? Thx. 回答1: You can also use IO::Tee. use strict; use warnings; use IO::Tee; open(my $fh1,">","tee1") or die $!; open(my $fh2,">","tee2") or die $!; my $tee=IO::Tee->new($fh1,$fh2); select $tee; #This makes $tee the default handle. print "Hey!\n"; #Because of the
