I have a file like this:
(define argc :: int)
(assert ( > argc 1))
(assert ( = argc 1))
(define c :: float)
(assert ( > c 0))
(assert ( = c 0))
now, i want to separate each block('#' is the delimeter), make them separate files, and then send them as... (5 Replies)
I'm Unix. I'm looking at "df" on Unix now and below is an example. It's lists the filesystems out in 512-blocks, I need this in 4k blocks. Is there a way to do this in Unix or do I manually convert and how?
So for container 1 there is 7,340,032 in size in 512-blocks. What would the 4k block be... (2 Replies)
If you are interested in security, check out this new directory of unix and linux related software tools.

It's an online con that is growing fast and stealing tens of millions of dollars.
An e-mail seemingly from a financial institution instructs you to log on to a legitimate-looking Web site. Such “phishing” attacks exploit a universal weakness in online security: passwords.

SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)NAME
ssh-keysign -- ssh helper program for host-based authentication
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen-
Controls whether ssh-keysign is enabled.
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host-
based authentication is used.
SEE ALSO ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)HISTORY
ssh-keysign first appeared in OpenBSD 3.2.
