quotes

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I have an array x=["1", "2", "3", ":*", ":+", "4", "5", ":-", ":/"] I'm trying to get rid of the double quotation inside of the array. I know I can use: x.to_s.gsub('"','') and it will output a string: "[1, 2, 3, :*, :+, 4, 5, :-, :/]" The desired output I want is an array not a string: [1, 2, 3, :*, :+, 4, 5, :

问题 I want to call a program with arguments built from an array in bash. I want bash to call: echo -arg1=simple -arg2="some spaces" from array=(echo -arg1=simple "-arg2=\"some spaces\"") or similar (I can adjust the way the items are created). Problem With "${array[@]}" bash calls: echo -arg1=simple '-arg2="some spaces"' But I do not want the single quotes. How to build and expand the array correctly? Example code #!/bin/bash set -x array=() array+=(echo) array+=(-arg1=simple) array+=("-arg2=\

问题 The forfiles command establishes several variables, indicated by a leading @ , which return data concerning the currently iterated item to the loop body. All the variables related to the path and name of the iterated item return the value enclosed in "" . Those are: @file , @fname , @ext , @path and @relpath . So: how can you get rid of the enclosing double-quotes? For example, the following code returns relative paths to text files in the given root directory: forfiles /P "C:\root" /M "*.txt

问题 I'm generating some javascript in my PHP code, and I need to assign some php variables to javascript variables. Unfortunately, sometimes my PHP variables contain quote marks. for instance: $foo = "'Dis here be a \"string\""; print "<script type='text/javascript'>var foo = '{$foo}';</script>"; will generate a javascript error because the resulting javascript will look like this: <script type='text/javascript'>var foo = '"'Dis here be a \"string\"'; I know I can use regexp on $foo to replace

问题 I am building this project in which I have to execute UNIX commands using ssh. Here is my question : When I execute the following command in a UNIX shell, echo "Hello World" It produces the output : Hello World With 5 spaces in between as the arguments were given within double quotes. I want to achieve the same effects with ssh as well. I am trying to escape the double quotes using backslash as follows : ssh localhost echo \"Hello World\" as I do not want bash to process the quotes. But it

问题 How can I properly escape a quote in a search string when using findstr.exe? Example: findstr /misc:"namespace=\"" *.cs > ns.txt This outputs to the console, instead of to the file I specified. I am doing this directly on the command line, not actually in a batch file, though that information might be useful too. 回答1: Please correct me if I'm wrong, but I think I've figured it out: findstr.exe /misc:^"namespace=\^"^" *.cs > ns.txt This seems to give the correct output, even if you have spaces

问题 This is in response to my previous question: PowerShell: -replace, regex and ($) dollar sign woes My question is: why do these 2 lines of code have different output: 'abc' -replace 'a(\w)', '$1' 'abc' -replace 'a(\w)', "$1" AND according to the 2 articles below, why doesn't the variable '$1' in single quotes get used as a literal string? Everything in single quotes should be treated as a literal text string, right? http://www.computerperformance.co.uk/powershell/powershell_quotes.htm http:/
