Execute dos2unix for directory recursively.

Will recursively find all files inside current directory and call for these files dos2unix command. Would break if you had spaces in file name.

find . -type f -exec dos2unix {} \;

Wouldn't break if you had spaces in file names.

find . -type f -print0 | xargs -0 dos2unix

JavaScript: sort object properties by value (numeric or string)

Sort object properties by value (values are text)

I have following object:

var cities={10:'Tashkent', 14:'Karakalpakiya', 16:'Andijan'};

I want sort it by city names, so after sort it should be:

var cities={16:'Andijan', 14:'Karakalpakiya', 10:'Tashkent'};

But I can't sort object properties, instead can convert object into array, then sort items.
