问题 What is reason behind writing #! /bin/bash at the very starting of every bash script ? I means, I know that it is kind of hack but I want to know how it exactly works ? 回答1: If you call the script with an explicit interpreter, like bash foo.sh /bin/bash foo.sh dash foo.sh sh foo.sh your choosen interpreter is used, no matter what the shebang says, which is just a comment. If you make the script executable, and start it: chmod a+x foo.sh ./foo.sh the kernel looks for the shebang and starts the

问题 Within a makefile I have a some variables. For a better understanding I added some comments: variable1 = value1 #A comment variable2 = true #can be set true or false variable3 = foo #can be foo or bar The problem is now, that the variables contain the given text and all spaces between the text and the # . The output of a simple echo shows the problem: echo "$(variable1) $(variable2) endOfEcho" value1 true endOfEcho How to avoid the spaces to be interpreted as variable's text? 回答1: With GNU

问题 Im looking for a way to remove MS Office style html comments, and everything in between. These are of the form: <!--[if gte mso 10]> blablabla blablabla <![endif]--> or <!--[if gte mso 9]> blablabla blablabla <![endif]--> The problem i'm encountering is that I do not want to remove ALL comments from the html.

I do this by simply pasting in the MySQL commands and making them into a PHP string. Like this... $queryStg = " update table1 set col1 = 1; drop table table2; "; $sqlQuery = mysqli_multi_query($mysqliLink, $queryStg); However I've always had to strip out the MySQL comments to get it to work. I'd prefer to retain these comments. Is there a way

问题 @Dianuj solved my issue a week ago, when I asked how I can get a recent comment above a post . That all worked very well, but yesterday, when I tested it, I saw a little issue, which I not want on my Wordpress site. Let me explain it to you...

I thank Dianuj for making my life easier.

问题 Simple question. No answer given anywhere on the internet? I program in C++ / C# in VS2015 community.
