sh-2.05$ who foo pts/0 Jun 19 21:50 (222-152-182-159.jetstream.xtra.co.nz)
So, I need to extract 222.152.182.159 using bash from the above string using bash scripting so I can update $CVSROOT.
MY_CURRENT_IP = $(who | cut -d( -f2 | cut -d\. -f1 | tr - \.)
The first cut picks up the open round bracket, and provides the right-hand portion.
The second cut finds the dot before jetstream, and returns the left.
The final tr converts the hyphens into dots.
