PAM_STRERROR(3) Linux-PAM Manual PAM_STRERROR(3)NAME
pam_strerror - return string describing PAM error code
SYNOPSIS
#include <security/pam_appl.h>
const char *pam_strerror(pam_handle_t *pamh, int errnum);
DESCRIPTION
The pam_strerror function returns a pointer to a string describing the error code passed in the argument errnum, possibly using the
LC_MESSAGES part of the current locale to select the appropriate language. This string must not be modified by the application. No library
function will modify this string.
RETURN VALUES
This function returns always a pointer to a string.

PAM_PUTENV(3) Linux-PAM Manual PAM_PUTENV(3)NAME
pam_putenv - set or change PAM environment variable
SYNOPSIS
#include <security/pam_appl.h>
int pam_putenv(pam_handle_t *pamh, const char *name_value);
DESCRIPTION
The pam_putenv function is used to add or change the value of PAM environment variables as associated with the pamh handle.
The pamh argument is an authentication handle obtained by a prior call to pam_start(). The name_value argument is a single NUL terminated
string of one of the following forms:
NAME=value of variable
In this case the environment variable of the given NAME is set to the indicated value: value of variable. If this variable is already
known, it is overwritten. Otherwise it is added to the PAM environment.
NAME=
This function sets the variable to an empty value. It is listed separately to indicate that this is the correct way to achieve such a
setting.
NAME
Without an '=' the pam_putenv() function will delete the corresponding variable from the PAM environment.
pam_putenv() operates on a copy of name_value, which means in contrast to putenv(3), the application is responsible to free the data.
RETURN VALUES
PAM_PERM_DENIED
Argument name_value given is a NULL pointer.
PAM_BAD_ITEM
Variable requested (for deletion) is not currently set.
PAM_ABORT
The pamh handle is corrupt.
PAM_BUF_ERR
Memory buffer error.
PAM_SUCCESS
The environment variable was successfully updated.

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:

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.
