Python capture subprocess output after termination

随声附和 提交于 2019-11-28 05:10:07
问题 I am trying to get subprocess output (on Windows) at the time the TimeoutExpired exception is raised. Any ideas? try: proc = subprocess.run(cmd,timeout=3) except subprocess.TimeoutExpired: print(???) 回答1: You need to use Popen and subprocess.PIPE in order to catch the process output when timeout expires. In particular Popen.communicate is what you need. Here is an example proc = subprocess.Popen(["ping", "192.168.1.1"], stdout=subprocess.PIPE) try: output, error = proc.communicate(timeout=2)

vbscript output to console

What is the command or the quickest way to output results to console using vbscript? Evan Anderson You mean: Wscript.Echo "Like this?" If you run that under wscript.exe (the default handler for the .vbs extension, so what you'll get if you double-click the script) you'll get a "MessageBox" dialog with your text in it. If you run that under cscript.exe you'll get output in your console window. RLH I know this was a while ago but maybe this will help others. It was found on Dragon-IT Scripts and Code Repository . You can do this with the following and stay away from the cscript/wscript

How to save the output of this awk command to file?

天涯浪子 提交于 2019-11-28 01:48:27
I wanna save this command to another text: awk '{print $2}' it extract's from text. now i wanna save output too another text. thanks awk '{ print $2 }' text.txt > outputfile.txt > => This will redirect STDOUT to a file. If file not exists, it will create it. If file exists it will clear out (in effect) the content and will write new data to it >> => This means same as above but if file exists, this will append new data to it. Eg: $ cat /etc/passwd | awk -F: '{ print $1 }' | tail -10 > output.txt $ cat output.txt _warmd _dovenull _netstatistics _avbdeviced _krb_krbtgt _krb_kadmin _krb_changepw

Writing to CSV from list, write.row seems to stop in a strange place

a 夏天 提交于 2019-11-28 01:39:54
I am attempting to merge a number of CSV files. My Initial function is aimed to: Look Inside a directory and count the number of files within (assume all are .csv) Open the first CSV and append each row into a list Clip the top three rows (there's some useless column title info I don't want) Store these results in an a list I've called 'archive Open the next CSV file and repeat(clip and append em to 'archive') When we're out of CSV files I wanted to write the complete 'archive' to a file in separate folder. So for instance if i were to start with three CSV files that look something like this.

Java: is there a way to run a system command and print the output during execution?

梦想的初衷 提交于 2019-11-28 01:25:52
I have a python script and it takes a long time to finish. I would like to run it from Java, but also output the script's output while it is executing, so that I can tell if it is properly running. I've searched and only found examples where we output the output after the system command has finished, rather than during its execution. Any way to do it while the script is running? Here's what I have public void doSomething() throws IOException { String[] callAndArgs = {"python", "/hi.py"}; Process p = Runtime.getRuntime().exec(callAndArgs); BufferedReader stdInput = new BufferedReader(new

Parsing the output of Bash's time builtin

五迷三道 提交于 2019-11-28 00:16:39
I'm running a C program from a Bash script, and running it through a command called time, which outputs some time statistics for the running of the algorithm. If I were to perform the command time $ALGORITHM $VALUE $FILENAME It produces the output: real 0m0.435s user 0m0.430s sys 0m0.003s The values depending on the running of the algorithm However, what I would like to be able to do is to take the 0.435 and assign it to a variable. I've read into awk a bit, enough to know that if I pipe the above command into awk, I should be able to grab the 0.435 and place it in a variable. But how do I do

Python: fastest way to write pandas DataFrame to Excel on multiple sheets

旧时模样 提交于 2019-11-28 00:14:33
问题 I need to export 24 pandas data frames ( 140 columns x 400 rows) to Excel , each into a different sheet. I am using pandas’ built-in ExcelWriter .

How to print variable inside quotation marks? [closed]

|▌冷眼眸甩不掉的悲伤 提交于 2019-11-28 00:11:04
I would like to print a variable within quotation marks. I want to print out "variable" I have tried a lot, what worked was: '"', variable", '"' – but then I have two spaces in the output -> " variable " When I do print '"'variable'"' without the comma I get a syntax error. How can I print something within a pair of quotation marks? you can use format : >>> s='hello' >>> print '"{}"'.format(s) "hello" Learn about format here: Format Mike Housky If apostrophes ("single quotes") are okay, then the easiest way is to: print repr(str(variable)) Otherwise, prefer the .format method over the %
