SSL_get_rbio - get BIO linked to an SSL object
SYNOPSIS
#include <openssl/ssl.h>
BIO *SSL_get_rbio(SSL *ssl);
BIO *SSL_get_wbio(SSL *ssl);
DESCRIPTION
SSL_get_rbio() and SSL_get_wbio() return pointers to the BIOs for the read or the write channel, which can be different. The reference
count of the BIO is not incremented.
RETURN VALUES

SSL_set_bio - connect the SSL object with a BIO
SYNOPSIS
#include <openssl/ssl.h>
void SSL_set_bio(SSL *ssl, BIO *rbio, BIO *wbio);
DESCRIPTION
SSL_set_bio() connects the BIOs rbio and wbio for the read and write operations of the TLS/SSL (encrypted) side of ssl.
The SSL engine inherits the behaviour of rbio and wbio, respectively. If a BIO is non-blocking, the ssl will also have non-blocking
behaviour.
If there was already a BIO connected to ssl, BIO_free() will be called (for both the reading and writing side, if different).
RETURN VALUES
SSL_set_bio() cannot fail.

Why do shell builtins like echo and pwd have binaries in /bin? When I do which pwd, I get the one in /bin. that means that I am not using the builtin version? What determines which one gets used? Is the which command a definitive way to determine what is being run when I enter pwd? (16 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)

Hi all,
I am learning POSIX shell programming, and the book I read, uses the let command for integer arithmetic.
I have downloaded and use the shellcheck program on Linux.
This programs says:
In POSIX sh, 'let' is undefined.

I don't know how to start this but here goes.
I've been "using" Linux for over 10 years, possibly more and I still feel like I'm nowhere

Hi all, (mainly Neo)...
I keep noticing that the SQRT code I wrote recently for a POSIX shell keeps appearing, (the green colour sticks out like a sore thumb).
So I decided to take a look on Google.
Guess what?
