Checksum is generally not used in this fashion. Using checksum to compare files from two different data sources is questionable. A checksum is usually used to insure that a single file or copy of that file is the same or has not been modified. Doing a checksum on linux is as simple as....

hi,
I wanted to know from anyone out there a way to perform a checksum command on a Microsoft FTP Server for a file and compare this with the checksum of the file that was transferred from a Unix machine.
Thanks,

Hi,
My Solaris Workstation has got 4 NICS, out of which one of them(bge3) is unplugged from the rest of the external network & connected to other interface(bge1). The isolated NIC serves as a simulated Ethernet Interface for my application under development.
Now, I'd like to capture RAW... (1 Reply)
Hello ,
When using vim, can ctag and cscope support recording search results and displaying the history results ? Once I jump to one tag, I can use :tnext to jump to next tag, but how can I display the preview search result? (0 Replies)
Hello ppl,
I'm working on a windows program simulating an existing Unix program,
the program is a firmware downloader, it sends a binary firmware file through the serial port (rs232) to a Set-Top Box running under unix system too, as i'm a poor unix user and not a unix programmer i choosed the... (10 Replies)
Hi,
When I use scp to copy a file from other location, I get the output like filename, time taken etc on console. I want to store that into a database table (in oracle).
Could someone give me some pointers on how to achieve this?

cksfv
CKSFV(1) General Commands Manual CKSFV(1)NAME
cksfv - tests and creates simple file verification (SFV) listings
SYNOPSIS
cksfv [-bciqrL] [-C dir] [-f file] [-g path] [file ...]
DESCRIPTION
cksfv is a tool for verifying CRC32 checksums of files. CRC32 checksums are used to verify that files are not corrupted. The algorithm is
cryptographically crippled so it can not be used for security purposes. md5sum (1) or sha1sum (1) are much better tools for checksuming
files. cksfv should only be used for compatibility with other systems.
cksfv has two operation modes: checksum creation and checksum verification
In checksum creation mode cksfv outputs CRC32 checksums of files to to stdout, normally redirected to an .sfv file.
In checksum verification mode cksfv reads filenames from an sfv file, and compares the recorded checksum values against recomputed check-
sums of files.
OPTIONS
These options are available
-b Strip dirnames from filenames that are checksumed. loads the files from original positions, but prints only basenames to catalogue
in sfv file.
-c Use stdout for printing progress and final resolution (files OK or some errors detected). This is useful for external programs
analysing output of cksfv. This also forces fflushes on the output when needed.
-C dir Change current directory before proceeding with a verification operation. This option is mostly obsoleted with -g option. Earlier
this was used to verify checksums in a different directory: cksfv -C foo -f foo/bar.sfv
-f file
Verify checksums in the sfv file
-g file
Change current directory to the path name of the file and verify checksums in the sfv.
-i Ignore case in filenames. This is used in the checksum verification mode.
-L Follow symlinks when recursing subdirectories. This option is used with the -r option.
-q Enable QUIET mode (instead of verbose mode), only error messages are printed
-v Enable VERBOSE mode, this is the default mode
-r recurse directories and check the .sfv files in each. Symlinks are not followed by default. This option cannot be used with -f and
-g options.
EXAMPLES
Verify checksums of files listed in 'foo/files.sfv':
cksfv -g foo/files.sfv
Create checksums for a set of files:
cksfv *.gz > files.sfv
Verify checksums of case-insensitive filenames listed in 'files.sfv'.
This is sometimes useful with files created by operating systems
that have case-insensitive filesystem names.
cksfv -i -g files.sfv
Check checksums of files 'foo' and 'bar' listed in 'files.sfv':
cksfv -g files.sfv foo bar
Create checksums of files matching /foo/bar/* and strip dirnames away:
cksfv -b /foo/bar/* > files.sfv
Recursively scan /foo/bar and verify each .sfv file:
cksfv -C /foo/bar -r
Same as previous, but starting from the current working directory
and also following symlinks during recursion:
cksfv -r -L
