using sed to get IP-address
Hi folks!
I need to get an ip address of a string that has the same apperance in every case. The string looks like this:
$node="node_ip:109.50.89.211; node:j20"
What I want to do is to extract the IP-address from this string using regular expression. Since I havn't worked much with regexp's I dont really know how to tackle this.
However, if one is able to extract ip from the pattern:
[0-9]{1-3 digits}.[0-9]{1-3 digits}.[0-9]{1-3 digits}.[0-9]{1-3 digits}
somehow...
Does any of you know how to do this?

plgxax
PLGXAX(3plplot) PLplot API PLGXAX(3plplot)
NAME
plgxax - Get x axis parameters
SYNOPSIS
plgxax(digmax, digits)
DESCRIPTION
Returns current values of the digmax and digits flags for the x axis. digits is updated after the plot is drawn, so this routine should
only be called after the call to plbox(3plplot) (or plbox3(3plplot)) is complete. See the PLplot documentation for more information.
Redacted form: plgxax(digmax, digits)
This function is used in example 31.
ARGUMENTS
digmax (PLINT *, output)
Pointer to variable with the maximum number of digits for the x axis. If nonzero, the printed label has been switched to a floating
point representation when the number of digits exceeds digmax.
digits (PLINT *, output)
Pointer to variable with the actual number of digits for the numeric labels (x axis) from the last plot.
