getfileinfo
GETFILEINFO(1) BSD General Commands Manual GETFILEINFO(1)NAME
/usr/bin/GetFileInfo -- get attributes of files and directories
SYNOPSIS
/usr/bin/GetFileInfo [-P -a[<attribute-letter>] | -c | -d | -m | -t] file ...
DESCRIPTION
/usr/bin/GetFileInfo is a tool to get the file attributes.
With no flags, GetFileInfo retrieves all information about the file. If exactly one option is provided, GetFileInfo retrieves and displays
just that information; supplying more than one is an error.
Flags:
-P Acts on a symlink file instead of the file the symlink resolves to.
-a[<attribute-letter>]
Gets a file's attribute bits where <attribute-letter> is one of the following:
a Alias file
b Has bundle
c Custom icon (allowed on folders)
d Located on the desktop (allowed on folders)
e Extension is hidden (allowed on folders)
i Inited - Finder is aware of this file and has given it a location in a window. (allowed on folders)
l Locked
m Shared (can run multiple times)
n File has no INIT resource
s System file (name locked)
t "Stationery Pad" file
v Invisible (allowed on folders)
z Busy (allowed on folders)
The value of a single attribute is printed as 0 for off or false, 1 for on or true. If no attribute letter is specified, the
value of all attributes is returned, with lowercase letters representing off or false, and uppercase representing on or true.
-t Gets the file type, a string of exactly four characters. If the type is not set, these will display as an empty pair of quo-
tation marks. Directories do not have types, so the type will be skipped if all information is being displayed; specifying -t
for a directory is an error.
-c Gets the file's creator, a string of four characters enclosed in quotation marks. If the creator is not set, these will dis-
play as an empty pair of quotation marks. Directories do not have creators, so the creator will be skipped if all information
is being displayed; specifying -c for a directory is an error.
-d Gets the creation date, a string of the form "mm/dd/yyyy hh:mm:ss" in 24-hour clock format.
-m Gets the modification date, a string of the form "mm/dd/yyyy hh:mm:ss" in 24-hour clock format.
RETURN VALUES
0 success
1 syntax error
2 any other error
SEE ALSO SetFile(1)EXAMPLES
The following command line gets and prints the creator for the "Late Breaking News" file:
/Developer/Tools/GetFileInfo -c "Late Breaking News"
This command line prints the modification date of "myFile":
/Developer/Tools/GetFileInfo -m myFile
