fileinfo
Provides information about a file
Calling Sequence
[x,ierr] = fileinfo(files)
Arguments
- files
a character string or a string column vector, file pathname
- x
an integer vector of size 13 containing information or an empty matrix if file does not exist.
if 'files' is a a string column vector, x wil be a matrix of size m x 13.
If a filename does not exist , it will return as output information a line of size 13 with Nan in each element of this line.
- ierr
error indicator, 0, if no error has occured
Description
x = fileinfo(file) returns
- x(1)
The file size
- x(2)
The file mode (decimal value).
- x(3)
The user id
- x(4)
The group id
- x(5)
The device number
- x(6)
The date of last modification
- x(7)
The date of last change
- x(8)
The date of last access
- x(9)
The device type (if inode device)
- x(10)
The blocksize for filesystem I/O (always 0 on Windows)
- x(11)
The number of blocks allocated (always 0 on Windows)
- x(12)
The inode
- x(13)
The number of hard links
Reference
This function is an interface to the C function stat.
Permissions are typically specified as octal numbers : dec2oct(x(2)) to convert
Numeric mode is from one to four octal digits (0-7), derived by adding up the bits with values 4, 2, and 1. Any omitted digits are assumed to be leading zeros. The first digit selects the set user ID (4) and set group ID (2) and sticky (1) attributes. The second digit selects permissions for the user who owns the file: read (4), write (2), and execute (1); the third selects permissions for other users in the file's group, with the same values; and the fourth for other users not in the file's group, with the same values.
Examples
w = fileinfo(SCI+'/etc/scilab.start') // file permission dec2oct(w(2)) // file date getdate(w(6)) // Checks write permission on a file w = fileinfo(SCI+'/etc/scilab.start') S_IWRITE = 128; // mask write permission S_IEXEC = 64; // mask exec permission S_IREAD = 256; // mask read permission S_IFCHR = 8192; // mask directory permission if ( bitand( w(2), S_IWRITE ) <> 0) then disp('WRITE PERMISSION on this file.'); else disp('NO WRITE PERMISSION on this file.'); end FILES = [SCI;SCIHOME;'not_exist_file';TMPDIR] [X,ERRS] = fileinfo(FILES)
