using “$@” will substitute the arguments as a list, without re-splitting them on whitespace (they were split once when the shell script was invoked), which is generally exactly what you want if you just want to re-pass the arguments to another program. Note that this is a special form and is only recognized as such … Read more
Well, there’s definitely no way to do exactly what you can do in Perl, because Python will complain about undefined variable names and a syntax error (missing comma, perhaps). But I would write it like this (in Python 2.X): print ‘%8s %8s %8s’ % (‘date’, ‘price’, ‘ret’) If you’re really attached to Perl’s syntax, I … Read more
If the encoding is UTF-8, the normal characters will work fine, and there is no reason not to use them. Browsers that don’t support UTF-8 will have lots of other issues while displaying a modern webpage, so don’t worry about that. So it is easier and more readable to use the characters and I would … Read more
Escape single quote with an additional single as Kirtan pointed out And if you are trying to execute a dynamic sql (which is not a good idea in the first place) via sp_executesql then the below code would work for you sp_executesql N’INSERT INTO SomeTable (SomeColumn) VALUES (”John””s”)’
General rule: quote it if it can either be empty or contain spaces (or any whitespace really) or special characters (wildcards). Not quoting strings with spaces often leads to the shell breaking apart a single argument into many. $? doesn’t need quotes since it’s a numeric value. Whether $URL needs it depends on what you … Read more
There is no way around it, you have to escape the values properly, or the HTML can’t be parsed properly. You can’t use Javascript to correct the code after it is parsed, because then it has already failed. Your example with proper HTML encoding would be: <p class=”example” data-example=”She said "<abbr title="What The F***">WTF</abbr>" on … Read more
Without quotes is better. It’s in {} so it’s obvious that you are not using barewords, plus it is both easier to read and type (two less symbols). But all of this depends on the programmer, of course.
Single quotes are not used at all by the cmd.exe command processor except to enclose the command to run within a FOR /F statement: for /f %%A in (‘someCommand’) do … Or to specify a string to process by FOR /F if the USEBACKQ option is used: for /f “usebackq” %%A in (‘some string’) do … Read more
str_replace(‘”‘, “‘”, $text); or Re-assign it $text = str_replace(‘”‘, “‘”, $text);
