Unix Tip #4071- April 4, 2012
GRABBING THE HIDDEN
To easily select all
hidden files, use the
following:
.[^.]* ..?*
For example,
echo .[^.]* ..?*
will output a list of
all hidden files in your
current directory.
.[^.]* selects all files
starting with a dot but NOT
having a dot as their
second character.
..?* selects all files
starting with two dots and
having at least one additional
character
Together, they will retrieve
ANY file starting with '.'
except '.' and '..' (even
tricky ones like '...hideme')
The ^ (caret) symbol can be
used as the first character
inside [ ] at any time to say
"not one of the following"
rather than the usual "any one
of the following."
[^0-9a-fA-F] will match any
character that is NOT a hex
digit.
