SSL_CTX_flush_sessions(3SSL) OpenSSL SSL_CTX_flush_sessions(3SSL)NAME
SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired sessions
SYNOPSIS
#include <openssl/ssl.h>
void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
void SSL_flush_sessions(SSL_CTX *ctx, long tm);
DESCRIPTION
SSL_CTX_flush_sessions() causes a run through the session cache of ctx to remove sessions expired at time tm.
SSL_flush_sessions() is a synonym for SSL_CTX_flush_sessions().
NOTES
If enabled, the internal session cache will collect all sessions established up to the specified maximum number (see
SSL_CTX_sess_set_cache_size()). As sessions will not be reused ones they are expired, they should be removed from the cache to save
resources. This can either be done
automatically whenever 255 new sessions were established (see SSL_CTX_set_session_cache_mode(3)) or manually by calling
SSL_CTX_flush_sessions().
The parameter tm specifies the time which should be used for the expiration test, in most cases the actual time given by time(0) will be
used.
SSL_CTX_flush_sessions() will only check sessions stored in the internal cache. When a session is found and removed, the remove_session_cb
is however called to synchronize with the external cache (see SSL_CTX_sess_set_get_cb(3)).
RETURN VALUES SEE ALSO ssl(3), SSL_CTX_set_session_cache_mode(3), SSL_CTX_set_timeout(3), SSL_CTX_sess_set_get_cb(3)1.0.1e 2013-02-11 SSL_CTX_flush_sessions(3SSL)

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.

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.
