外壳按字母顺序对输出进行排序

Question

I have a script with output for example acd txt iso ez I need to sort it alphabetically. These are file extensions so I cant compile it together in one word and then split up. Can anyone help me?

Answer 1

If your the name of your script is foo and it writes to stdout a string such as acd txt iso ez , you can get the sorted list by, for instance:

sorted_output=$(foo|xargs -n 1|sort)

Of course, depending on what you are going to do with the result, it might make more sense to store it into an array.
