问题 TLDP's Advanced Bash Scripting Guide states that shell scripts shouldn't be used for "situations where security is important, where you need to guarantee the integrity of your system and protect against intrusion, cracking, and vandalism." What makes shell scripts unsuitable for such a use case? 回答1: Because of the malleability of the shell, it is difficult to verify that a shell script performs its intended function and only that function in the face of adversarial input. The way the shell

问题 I have a Jmeter test plan where I want my HttpSampler to send a post request. The body of the request should contain Json as follows: { "productIds" : [ "p1", "p2", ... ] } I have setup a random variable generator that returns well-formed productId with every call. What I would like to do is generating the payload by filling productIds of random pid's taken from the generator, directly in the body of the request. Something like (suppose *** is the scripting escape): { "productIds" : [ *** for

问题 I am having a list of machine ips in a ant property. <property name="machines" ip="10.10.10.1;10.10.10.2;10.10.10.3"/> I have to copy one file to all the machines(all the machines are windows machines). So I want to split this string and to use it inside a for loop. Inside that forloop i will execute the copy command. <exec executable="cmd.exe"> <pre> </pre> <arg line="/C COPY /Y sample.txt \\${machine_ip}\Shared_folder\sample.txt"/> <pre> </pre> </exec> Now how to split and use it inside for

问题 Given these 2 typescript files api/Token.ts interface Token { code: string } export default Token and index.ts export * from './api/Token' tsc 1.5 with the --declarations switch will generate two .d.ts files (with similar content) api/Token.d.ts interface Token { code: string; } export default Token; and index.d.ts export * from './api/Token'; Running grunt-dts-bundle with the following options dts_bundle: { release: { options: { name: 'my-module', main: 'index.d.ts' } } } will generate an

问题 this is quite a difficult topic by all accounts. I am building a website that requires users to upload large (multi-GB). What is the best way allow users to upload a file on a website and allow the file upload to be resumed should it fail? What is the way to write this in rails? Any ideas greatly appreciated. Max. 回答1: No browsers support resuming uploads. From my Googling, Flash doesn't seem to, either. Though I don't know enough about Java to say it's impossible, there don't seem to be any

问题 I think this question is rather easy for you shell scripting monsters. I am looking for the most elegant and shortest way to create symbolic links to shared libraries for Unix by means of a bash shell script. What I need is starting out with a list of shared library files such as "libmythings.so.1.1, libotherthings.so.5.11", get the symbolic links created such as: libmythings.so -> libmythings.so.1 -> libmythings.so.1.1 libotherthings.so -> libotherthings.so.5 -> libotherthings.so.5.11 The

问题 I have a little command line tool that reads from stdin. On the command line I would run either... ./foo < bar or ... cat bar | ./foo With a gziped file I can run zcat bar.gz | ./foo in Python I can do ... Popen(["./foo", ], stdin=open('bar'), stdout=PIPE, stderr=PIPE) but I can't do import gzip Popen(["./foo", ], stdin=gzip.open('bar'), stdout=PIPE, stderr=PIPE) I wind up having to run p0 = Popen(["zcat", "bar"], stdout=PIPE, stderr=PIPE) Popen(["./foo", ], stdin=p0.stdout, stdout=PIPE,

问题 I am trying plot data sets consisting of 3 coordinates: X-coordinate, x-coordinate and the number of occurrences. example: 1 2 10 3 1 2 3 2 1 I would like to draw for every line a dot at x,y with a diameter which is depending on the third value. Is that possible with Gnuplot? 回答1: Create a 2D plot with variable point size. See the demo. Example: plot 'dataFile.dat' u 1:2:3 w points lt 1 pt 10 ps variable 来源： https://stackoverflow.com/questions/2689403/gnuplot-dot-plot-with-data-depending-dot

问题 I'm trying to get an understanding of how I can use co-routines to "pause" a script and wait until some processing is done before resuming. Perhaps I'm looking at co-routines in the wrong way. But my attempt is structured similar to the example given in this answer. The loop in loop.lua never reaches a second iteration, and hence never reaches the i == 4 condition required to exit the running loop in the C code. If I do not yield in loop.lua , then this code performs as expected. main.cpp
