DSA_SIG_new(3) OpenSSL DSA_SIG_new(3)NAME
DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects
SYNOPSIS
#include <openssl/dsa.h>
DSA_SIG *DSA_SIG_new(void);
void DSA_SIG_free(DSA_SIG *a);
DESCRIPTION
DSA_SIG_new() allocates and initializes a DSA_SIG structure.
DSA_SIG_free() frees the DSA_SIG structure and its components. The values are erased before the memory is returned to the system.
RETURN VALUES
If the allocation fails, DSA_SIG_new() returns NULL and sets an error code that can be obtained by ERR_get_error(3). Otherwise it returns a
pointer to the newly allocated structure.
DSA_SIG_free() returns no value.

DSA_SIG_new() and DSA_SIG_free() were added in OpenSSL 0.9.3.

DSA_do_sign(3) OpenSSL DSA_do_sign(3)NAME
DSA_do_sign, DSA_do_verify - raw DSA signature operations
SYNOPSIS
#include <openssl/dsa.h>
DSA_SIG *DSA_do_sign(const unsigned char *dgst, int dlen, DSA *dsa);
int DSA_do_verify(const unsigned char *dgst, int dgst_len,
DSA_SIG *sig, DSA *dsa);
DESCRIPTION
DSA_do_sign() computes a digital signature on the len byte message digest dgst using the private key dsa and returns it in a newly
allocated DSA_SIG structure.
DSA_sign_setup(3) may be used to precompute part of the signing operation in case signature generation is time-critical.
DSA_do_verify() verifies that the signature sig matches a given message digest dgst of size len. dsa is the signer's public key.
RETURN VALUES
DSA_do_sign() returns the signature, NULL on error. DSA_do_verify() returns 1 for a valid signature, 0 for an incorrect signature and -1
on error. The error codes can be obtained by ERR_get_error(3).

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
12FX009:5 dpontius$ ls
ââWord FinderÂŽ Plusâ˘
12FX009:5 dpontius$ rm... (29 Replies)
