Strange,
it seems that you're running this:

Code:

awk 'END { if (f) print x } $0 ~ v && f++ /^--/ { if (f) print x; x = f = 0 }
{ x = x ? x RS $0 : $0 }' v="^IP=172.18.0.1$" file

instead of this:

Code:

awk 'END { if (f) print x } $0 ~ v && f++
/^--/ { if (f) print x; x = f = 0 }
{ x = x ? x RS $0 : $0 }' v="^IP=172.18.0.1$" file

...
Anyway,
try separating the statments explicitly:

Code:

awk 'END { if (f) print x } $0 ~ v && f++;
/^--/ { if (f) print x; x = f = 0 }
{ x = x ? x RS $0 : $0 }' v="^IP=172.18.0.1$" file

How I run that awk script in Solaris unix shell? (Couple of lines, error comes if I run it on one line).

The last version should work well even on one line,
could you post the command and the errors (just copy/paste them from your terminal)?

awk 'END { if (f) print x } $0 ~ v && f++; /^--/ { if (f) print x; x = f = 0 } { x = x ? x RS $0 : $0 }' v="^IP=172.18.0.1$" list.txt
Illegal variable name.

I cannot reproduce it, could you try it with nawk?

Try this also:

1. Put this code into a file (for example Hone1975.awk) preserving the format:

Code:

END { if (f) print x }
$0 ~ v && f++
/^--/ { if (f) print x; x = f = 0 }
{ x = x ? x RS $0 : $0 }

2. Run it like this:

Code:

nawk -f Hone1975.awk v="^IP=172.18.0.1$" list.txt
