1. Searching for files with specific attributes.

To search for specific attributes you must enter a string pattern, which specifies which attributes are searched for, and if they should be enabled or disabled.

A single attribute is represented with the following format:

<attribute>+ or <attribute>-

The plus sign means that the file must have that attribute set, a minus sign means that the file must not have that attribute set.

The various <attribute> identifiers are as follows:

Attributes in WINDOWS
Attribute letterWhat it stands for
r
read only
a
archive
h
hidden
s
system
d
directory
l
symlink
t
temporary
p
sparse
c
compressed
e
encrypted

Attributes in Unix/Linux (Permissions)
Permissions lettersWhat it stands for
ur
user read
uw
user write
ux
user execute
gr
group read
gw
group write
gx
group execute
or
others read
ow
others write
ox
others execute
us
set user ID
gs
set group ID
sb
sticky bit

Attributes in Unix/Linux (File Types)
File Types lettersWhat it stands for
b
block
c
character
d
directory
f
fifo
l
symlink
r
regular
s
socket

In Unix/Linux you may also use octal representation of permissions. For example 0750 is the same as ur, uw, ux, gr and gx combined.

2. Advanced patterns

Several attributes may be combined together with an AND relationship.

Just specify one pattern after another.

For example: r+s+h+ matches files that have all three: read-only, hidden and system attributes set.

Furthermore, such groups of AND attributes may be combined together with an OR relationship.

This is done by using the "|" character (vertical bar). For example: r+|s+h+ matches files that have either:

It is possible to negate AND sequences using "!" character specified at the start of the sequence.

For example: !r+s+h+ matches files that don't have all three: read-only, hidden and system attributes set.

The matched file may have none, one or more of those attributes set, but not all of them.

Negation only applies to AND sequences, thus pattern !r+|!s+h+ matches files that either:

You cannot use parenthesis to separate sequences.

3. Examples


Example in Windows
Examples lettersHow it is interpreted
a+s-h-
matches files that have archive attribute set and don't have neither system nor hidden attributes set
e+|c+
matches files that are either compressed or encrypted (these are NTFS attributes)
d-
matches files but not directories

Example in Unix/Linux
Examples lettersHow it is interpreted
uw+|gw+|ow+
matches files that are writeable either by user, group or anybody else
222+
matches files that are writeable by user, and by group, and by anybody else
d+ox+
matches directories that are accessible by anybody
!700+
matches files that are not fully accessible to the user
