    when I move to /dev and run ls , I found some entries/devices (device files) that grabbed my attentions like :

     

    /dev/audit

    /dev/cfglock

    /dev/echo

    /dev/error

    /dev/nulls

    /dev/nvram

    /dev/xti

     

    any clarification about that devices?

    /dev/audit - part of aix auditing subsystem

    /dev/cfglock - used by aix odm subsystem (cfgmgr)

    /dev/echo - standard unix descriptor/device for the echo service

    /dev/error - standard unix descriptor for stderr (standard error)

    /dev/null - standard unix descriptor for null device

    /dev/nvram - descriptor for virtual memory device

    /dev/xti - directory that usually holds /dev/xti/utp and /dev/xti/tcp..network devices

    UNIX is built on the concept of filenames to manipulate and manage resources that aren't actually files...how cool is that.
