How can I know the type of each element in the output of ls -l?
0
I was checking what exactly each field is in the output of ls -l. The example in this post solves my question. But again I'm wondering what type of each field is. The strings are obvious. But how about the numbers? Like 10, 2048, are they integers or strings? Is there any way I can check the type of each field?

ls -lproduces a string. If you feed the output ofls -lto bash or awk or another program, how that program interprets the strings is up to it.

Ok, I was confused because I saw someone read the output usingscanf ("%s, %s, %s, %s, %d, %s, %s, %s, %s， some_variable, some_variable, ...")Like why the middle one is%dinstead of%s
