You can use the prtconf command to list your AIX hardware configuration. including CPU's, memory, adapters, disk and network. The prtconf command is available for the current version of AIX 4.3.3, and on AIX 5. For those running older versions of AIX, here's a list of commands that provide the same information: General prtconf - list system configuration lscfg [-v] - devices (-v = verbose for microcode levels, etc) lscfg -v - devices verbose (microcode level, firmware, etc) lsdev -Cc adapter - adapter cards lsdev -Cc disk - disks lsdev -Cc processor - CPU's lsattr -El sys0 - serial number, model number, memory AIX oslevel - AIX OS level instfix -i |grep ML - AIX maintenance level lslpp -l - installed SW and levels Disk lsvg -o - active volume groups lsvg -p vgname - disk drives in VG lsvg -l vgname - LV's in VG (ie: lsvg -l hekvg) lslv lvname - LV detail lslv -l lvname - LV disk location lspv - disks lspv -l hdisk# - LV's residing on a disk Network lsdev -Cc if -List network interfaces netstat -rn -List network gateways
EMAILING A FILE (ATTACHMENT) FROM UNIX USING THE MAIL COMMAND Here is an example. I tarred up a file (ktl.tar) and am going to uuencode it as "attachment.tt" and email it.
uuencode ktl.tar attachment.tt | mail kevin.lloyd@spirentcom.com
To view the attachment, the person receiving the email only needs to untar it.
When the person receives the attachment it will be called "attachment.tt"; when they untar it, it will be called "ktl.tar".
