Solaris

Hi,

I am getting read error when i run cksum </dir> but this command runs successfully for the files and in different server it runs for both files and directories. I am using in both the servers solaris 10 with patch 148888-03. Please suggest...

Code:

# cksum ravi(directory)
3454912345      0 ravi [read error]

Thanks in advance...

Assuming: You want to checksum the directory file itself ( that is what your command seems to imply) then you need read and execute privilege on ravi. You can also get errors when the directory file is corrupted.

What does the command ls -ld ./ravi show? Please post the output.


What are you trying to do? it sounds like you want to checksum everything in the directory.

Maybe like this?:

Code:

cksum $(find ./ravi -type f)

Hi Jim,

Thanks for you reply..

I want to run chsum on directory so that it will show the chsum value and size of the directory (like below output) here we can see the 96 as the size of directory but from my first post we can see the cksum value but it can't show the size of the directory.

# cksum alerts
1721028050 96 alerts
#ls -ld alerts

I ran truss for the command then it is showing error while reading here is the output where we are getting error.

read(3, 0x0002260A, 4096) Err#21 EISDIR
close(3) = 0
ioctl(1, TCGETA, 0xFFBFED14) = 0
fstat64(1, 0xFFBFEC30) = 0
4294967295 0 lib [read error]write(1, " 4 2 9 4 9 6 7 2 9 5\t 0".., 29) = 29

write(1, "\n", 1) = 1
_exit(1)

As you suggested, Please find below output. I logged in the server as root.

#ls -ld ravi
drwxr-xr-x 4 ramesh other 43 Mar 21 06:00 ravi

Hi.

Many years ago in SunOS, one could use a number of standard commands on directories. AFAIK, that cannot be done these days.

Linux cksum produces:

Code:

$ cksum cohorts/
cksum: cohorts/: Is a directory

which is a useful error message.

Whereas, as you have noticed:

Code:

vm-solaris ~ $ cksum Desktop/
4294967295      0       Desktop/ [read error]

In other words (from my perpective) you cannot do that.

Best wishes ... cheers, drl
