Thanks to all ...
Now I'm curious about something else:
Is the mode in a stat(file) readout something still different
than octal or decimal?
I see `33261' show up in the `mode' slot on a file with 755 permissions
(from perldoc -f stat:
[...]
($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,
$atime,$mtime,$ctime,$blksize,$blocks)
= stat($filename);
[...]
ls -l file
-rwxr-xr-x 1 reader staff 510 2009-07-06 15:25 file
My homemade script `mystat' prints out the various values:
./mystat file
file:
dev = 47776050
ino = 88208
mode = 33261
nlink = 1
uid = 1000
gid = 10
rdev = 4294967295
size = 510
atime = 1246912030
mtime = 1246911903
ctime = 1246911903
blksize = 512
blocks = 2
The mode field contains more information than just the
read/write/execute permissions:
man 2 stat
[ SNIP ]
The following flags are defined for the st_mode field:
S_IFMT 0170000 bit mask for the file type bit fields
S_IFSOCK 0140000 socket
S_IFLNK 0120000 symbolic link
S_IFREG 0100000 regular file
S_IFBLK 0060000 block device
S_IFDIR 0040000 directory
S_IFCHR 0020000 character device
S_IFIFO 0010000 FIFO
S_ISUID 0004000 set UID bit
S_ISGID 0002000 set-group-ID bit (see below)
S_ISVTX 0001000 sticky bit (see below)
S_IRWXU 00700 mask for file owner permissions
S_IRUSR 00400 owner has read permission
S_IWUSR 00200 owner has write permission
S_IXUSR 00100 owner has execute permission
S_IRWXG 00070 mask for group permissions
S_IRGRP 00040 group has read permission
S_IWGRP 00020 group has write permission
S_IXGRP 00010 group has execute permission
S_IRWXO 00007 mask for permissions for others (not in
group)
S_IROTH 00004 others have read permission
S_IWOTH 00002 others have write permission
S_IXOTH 00001 others have execute permission
