Thank you for both replies. I apologize for not responding sooner and for bumping a thread so long after it was replied to. A family emergency prevented (or, at least distracted from) replying sooner. The suggestions are now being turned into a working solution.
One question, though... Since the separator of choice, "|", follows both the factors at the beginning of the line and each of the subsequent trial entries, wouldn't only one existent trial be preserved from the file? Suppose there's a line:
8,6|NO,47,6.110|NO,47,3.910
Wouldn't $factor be "8,6" and $trial be "NO,47,6.110", the first trial? It seems like the second would be discarded and no more than 2 trials would ever be preserved. But I could easily be reading wrong. If not, though, perhaps I would be better off with a file structure like:
and IFS=":". What think ye? Again, many thanks.

Hi,
I need to write a shell script (ksh) to read contents starting at a specific location from one file and append the contents at specific location in another file. Please find below the contents of the source file that I need to read the contents from,

Hi, I am a newb as far as shell scripting and SED goes so bear with me on this one.
I want to basically append to each line in a file a delimiter character and the line's line number e.g
Change the file from :-
aaaaaa
bbbbbb
cccccc
to:-
aaaaaa;1
bbbbbb;2
cccccc;3

Hi
Suppose I have a variable called filename and it it contains the name of a file. I then would like to append an extension to that filename. The filename currently has no extensions.
How do I do this?

Hi,
I have the following file,
ABC.txt:
ABC=123
DEF=234
FGH=345
Based on my validation and conditional processing it is observed that i need to comment or append # before DEF=234
so the same file ABC.txt should look as follows
ABC=123
#DEF=234
FGH=345
Sorry if its a... (6 Replies)

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.
SEE ALSO dsa(3), ERR_get_error(3), rand(3), DSA_free(3)HISTORY
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.
