I have to write a script that finds all executable files in a directory. So I tried several ways to implement it and they actually work. But I wonder if there is a nicer way to do so.
So this was my first approach:
ls -Fla | grep \*$
This works fine, because the -F flag does the work for me and adds to each executable file an asterisk, but let's say I don't like the asterisk sign.
So this was the second approach:
ls -la | grep -E ^-.{2}x
This too works fine, I want a dash as first character, then I'm not interested in the next two characters and the fourth character must be a x.
But there's a bit of ambiguity in the requirements, because I don't know whether I have to check for user, group or other executable permission. So this would work:
ls -la | grep -E ^-.{2}x\|^-.{5}x\|^-.{8}x
So I'm testing the fourth, seventh and tenth character to be a x.
Now my real question, is there a better solution using ls and grep with regex to say:
I want to grep only those files, having at least one x in the ten first characters of a line produced by ls -la
