排除awk无法正常工作的文件夹

Question

I've to make a folder contents list using ls -alis and using awk to filter the results.

I'm having some problems with $11 != "." && $11 != ".." $11 != "." && $11 != ".." . I don't want to display the folder . and the folder .. but they are still here.

ls --color -alis /home/user/ | 
tr -s ' ' | cut -d " " -f11 |
awk '$1 !~"^/\./$" { print $1 }'

I've tried $11 !~ "^/./$" as well.

Answer 1

Parsing output of ls is not recommended as filenames can have white-spaces newlines etc and will break your piped commands.

For your requirement you can just use this printf with xargs :

printf "%s\0" * | xargs -0 ls --color -Alis

Answer 2

Don't double quote the regex, and the anchor points ( ^ and $ ) go inside the regex:

awk '$11 !~ /^\.\.?$/ { print }'

That doesn't match a line where field 11 contains one or two dots (only).

This deals with the problems with the awk script; it is, however, debatable whether you should be parsing the output of ls as it is can be ambiguous.
