  34. \fBunix_update\fR [\&.\&.\&.]
  35. .SH "DESCRIPTION"
  36. .PP
  37. \fIunix_update\fR
  38. is a helper program for the
  39. \fIpam_unix\fR
  40. module that updates the password of a given user\&. It is not intended to be run directly from the command line and logs a security violation if done so\&.
  41. .PP
  42. The purpose of the helper is to enable tighter confinement of login and password changing services\&. The helper is thus called only when SELinux is enabled on the system\&.
  43. .PP
  44. The interface of the helper \- command line options, and input/output data format are internal to the
  45. \fIpam_unix\fR
  46. module and it should not be called directly from applications\&.
