I am writing a C program that part of the idea is to using a command line parameter to control not to run certain part of the sub program.
I am totally new to C, I do not have any idea how to pass a command line arguments from a C program.
Can anyone help ?!

Anyone know how to set it up so that when at command line in unix (specifically solaris 2.5.1), and you hit the tab it will finish the command with the nearest file that matches? AND how to set it up so using up and down arrows access your previous commands?
Thanks for all the help here, i've had... (3 Replies)
Hello,
I am trying to replace a string with a paramter given along with the script.
I am replacing application1 to application2 with the script:

Hi,
I need to check if a parameter provided at the command line is equal to --.How can i do that ? Please help me.

"$#" gives the number of command-line arguments. How do you get the last command-line parameter (or any particular one determined by a variable)? I thought it would be "${$#}", but that produces something completely unexpected. (4 Replies)
I have a simple script that builds a complex program call which passes a number of parameters to the program. I'm trying to enhance the script to include the value of the command line parameter in the name of a file being created. The problem I'm having is that the parameter may include a forward...

i am a beginner, i want to make a program that takes any command line arguments... and print it out in reverse.
ie. if the command line argument is "thanks for helping me"
i want it to output "me helping for thanks" :D
i have tried using the reverse command, but i cant get it working!!

Hello Everyone,
I have been trying to complete a shell script where, I need to increment the date depending on the file (depending on the date) availability on the remote server.

dsa_generate_parameters
DSA_generate_parameters(3) OpenSSL DSA_generate_parameters(3)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.
