hi to all members in this forums .. Nice to meet you...
i only have a questions about command utility of "dd":
for example i will type:
pico trial
this is my file.
and save it and type chmod a+x trial
can there be a way that instead of typing:
so that my output in script trial will all become UPPERCASE.
And i want to change this "dd" command to "copyconv" just like the functionality of "dd" command also.. and the "conv=ucase" i would like to do the "conv=u" so that the content of my script trial will become UPPERCASE..
Hi All,
One small request. In UNIX/LINUX we can have our own aliases in .bashrc file. My doubt is when we add a new alias and if it is tried in already opened terminals it will not work, may be it is not going to recognise. Bit when we use the same alias in new terminal it will work. I... (1 Reply)
Folks;
I know this might sound stupid, but Can i alias a web link to another web link in a UNIX server?
Let say i have a web link named http://test.new.com/wiki
Can i alias that so when i click on it or i type it in the browser address it opens but the link in the browser say something like:... (1 Reply)
HI All,
I have a small question/clarification/doubt . Does anyone know how to provide alias in the mails that come from Unix servers.
Like i have a Unix server that generates status mails every hour for a scheduled job , it sends me mails with status with the ID in from field as... (3 Replies)
Here's my opportunity.... I want to turn off the * expansion, execute the shell script and have it see the arguement with the * and not all the filenames, and then set +f once the script is executed.
1) I have an alias set as follows:
alias scp='set -f; /opt/dir1/dir2/script.sh ; set +f'... (1 Reply)
Hi,
is it normal, that the IP alias (service IP) can't be seen with ifconfig -a , as eth0:1 for example
the IP is on the node, you can ping it, and open ports for that IP
look at this:
# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
link/loopback... (4 Replies)
HI Guys,
I hope you are well. I am trying to write a script that gets executed every time i open a shell (cshell). I have two questions about that
1) I need to enter these commands
$ echo $DISPLAY
$ setenv $DISPLAY output_of_echo_$display_command
How can i write a... (2 Replies)
Hello,
I need to rediret the directory location at run time as:-
If I type cd /dir1/dir2 then it should take me to /dir1/dir3 at run time.
Inside dir1, both dir2 and dir3 directories are present.
Could anyone guild me over it?
Thanks

Being able to mark in an alias definition a point of minimal abbreviation, an old feature of VAX/VMS shell (DCL) would be really nice in modern *nix shells.
In DCL you used to be able to define an alias (in its own weird syntax) which would be something like this:
$ alias fuz*zyanimals="cat... (5 Replies)

dsa_generate_parameters
DSA_generate_parameters(3SSL) OpenSSL DSA_generate_parameters(3SSL)NAME
DSA_generate_parameters - generate DSA parameters
SYNOPSIS
#include <openssl/dsa.h>
DSA *DSA_generate_parameters(int bits, unsigned char *seed,
int seed_len, int *counter_ret, unsigned long *h_ret,
void (*callback)(int, int, void *), void *cb_arg);
DESCRIPTION
DSA_generate_parameters() generates primes p and q and a generator g for use in the DSA.
bits is the length of the prime to be generated; the DSS allows a maximum of 1024 bits.
If seed is NULL or seed_len < 20, the primes will be generated at random. Otherwise, the seed is used to generate them. If the given seed
does not yield a prime q, a new random seed is chosen and placed at seed.
DSA_generate_parameters() places the iteration count in *counter_ret and a counter used for finding a generator in *h_ret, unless these are
NULL.
A callback function may be used to provide feedback about the progress of the key generation. If callback is not NULL, it will be called as
follows:
o When a candidate for q is generated, callback(0, m++, cb_arg) is called (m is 0 for the first candidate).
o When a candidate for q has passed a test by trial division, callback(1, -1, cb_arg) is called. While a candidate for q is tested by
Miller-Rabin primality tests, callback(1, i, cb_arg) is called in the outer loop (once for each witness that confirms that the
candidate may be prime); i is the loop counter (starting at 0).
o When a prime q has been found, callback(2, 0, cb_arg) and callback(3, 0, cb_arg) are called.
o Before a candidate for p (other than the first) is generated and tested, callback(0, counter, cb_arg) is called.
o When a candidate for p has passed the test by trial division, callback(1, -1, cb_arg) is called. While it is tested by the Miller-
Rabin primality test, callback(1, i, cb_arg) is called in the outer loop (once for each witness that confirms that the candidate may be
prime). i is the loop counter (starting at 0).
o When p has been found, callback(2, 1, cb_arg) is called.
o When the generator has been found, callback(3, 1, cb_arg) is called.
RETURN VALUE
DSA_generate_parameters() returns a pointer to the DSA structure, or NULL if the parameter generation fails. The error codes can be
obtained by ERR_get_error(3).
BUGS
Seed lengths > 20 are not supported.

DSA_generate_parameters() appeared in SSLeay 0.8. The cb_arg argument was added in SSLeay 0.9.0. In versions up to OpenSSL 0.9.4,
callback(1, ...) was called in the inner loop of the Miller-Rabin test whenever it reached the squaring step (the parameters to callback
did not reveal how many witnesses had been tested); since OpenSSL 0.9.5, callback(1, ...) is called as in BN_is_prime(3), i.e. once for
each witness.
