问题
I am trying to display the hidden files from a directory using the ls command alone, except for . and ...
ls -lAd .*
But the command returns . and .. directory names also in the output . What's wrong in this command even though I mentioned "A" option with ls .
回答1:
You could use GLOBIGNORE internal variable.
$ GLOBIGNORE=.:..
$ ls -ld .*

This is here for reference but the answer is given by @anishsane below.
Your glob is wrong:
.*
will be expanded to ., and ... You can either change the glob to something like:
.??*
but this will not match hidden files like: .a, .b. Or .[^.]* but that will not match files like ..a, ..b, combining both might be an option:
ls -lAd .[^.]* ..?*
But that will most likely yeild: ls: error: ..?* no such file or directory. Enabling nullglob will prevent this:
shopt -s nullglob
ls -lAd .[^.]* ..?*
This will however expand to ls -lAd if no hidden files are in the directory, which will show current working directory (.)
Alternative you can pipe the output from ls to awk, but that will most likely get rid of the colors:
ls -lA | awk '$9 ~ /^\./'
Also consider reading: Why you shouldn't parse the output of ls(1)
