How to find pattern inside a specific pattern and print both of them

Question

I want to only print server name as header and whatever sas service is not up inside it.if everything is up inside server it should not be printed.

File content-

he2unix554 Server: 

SAS servers status:

SAS OLAP Server 1 is UP

SAS Object Spawner 1 is UP

SAS CONNECT Spawner 1 is NOT up

SAS Environment Manager Agent is NOT up

he2unix555 Server: 

SAS servers status:

SAS OLAP Server 1 is UP

SAS Object Spawner 1 is UP

SAS CONNECT Spawner 1 is NOT up

SAS Environment Manager Agent is UP

he2unix556 server:

SAS servers status:

SAS OLAP Server 1 is UP

SAS Object Spawner 1 is UP

SAS CONNECT Spawner 1 is UP

SAS Environment Manager Agent is NOT up

he2unix557 Server

SAS servers status:

SAS OLAP Server 1 is NOT up

SAS Object Spawner 1 is UP

SAS CONNECT Spawner 1 is UP

SAS Environment Manager Agent is UP

he2unix558 Server

SAS Web Infrastructure Data Server is UP

SAS OLAP Server 1 is UP

SAS Object Spawner 1 is UP

SAS DIP Job Runner 1 is UP

SAS CONNECT Spawner 1 is UP

SAS Cache Locator Service ins_41415 is NOT up

SAS Environment Manager Agent is NOT up

he2unix559 Server

SAS OLAP Server 1 is UP

SAS Object Spawner 1 is UP

SAS CONNECT Spawner 1 is UP

SAS Environment Manager Agent is UP

Desired Output-

   he2unix554 Server: 

    SAS CONNECT Spawner 1 is NOT up

    SAS Environment Manager Agent is NOT up

    he2unix555 Server: 

    SAS CONNECT Spawner 1 is NOT up

    he2unix556 server:

    SAS Environment Manager Agent is NOT up

    he2unix557 Server:

    SAS OLAP Server 1 is NOT up

    he2unix558 Server:

    SAS Cache Locator Service ins_41415 is NOT up

i tried below which is giving me server header even if everything is up inside it.

sed -n '/^he2unix5/ { p } ; /NOT up$/ { p }' sasserverstatus.log

he2unix554 Server: 

SAS CONNECT Spawner 1 is NOT up

SAS Environment Manager Agent is NOT up

he2unix555 Server: 

SAS CONNECT Spawner 1 is NOT up

he2unix556 server:

SAS Environment Manager Agent is NOT up

he2unix557 Server:

SAS OLAP Server 1 is NOT up

he2unix558 Server:

SAS Cache Locator Service ins_41415 is NOT up

**he2unix559 Server:**   #don't want this in output

are there really empty lines between each pair of lines? – RomanPerekhrest Oct 13 '17 at 18:56 — RomanPerekhrest, Oct 13 '17 at 18:56

Awk is more suitable for such cases:

awk '/^he2unix/{ sn=$0; f=1; sas=0 }f && /NOT up/{ if(!sas++) print sn; print $0 }' file

The output:

he2unix554 Server: 
SAS CONNECT Spawner 1 is NOT up
SAS Environment Manager Agent is NOT up
he2unix555 Server: 
SAS CONNECT Spawner 1 is NOT up
he2unix556 server:
SAS Environment Manager Agent is NOT up
he2unix557 Server
SAS OLAP Server 1 is NOT up
he2unix558 Server
SAS Cache Locator Service ins_41415 is NOT up
SAS Environment Manager Agent is NOT up

Thanks a lot. it does exactly what i wanted. can you please elaborate what it is doing. i know only basic of awk. — DGaynar, Oct 13 '17 at 18:59

It may be laughable :-) but the following sed command seems to work for me:

sed -n '/^he2unix5/ {h}; /NOT up$/ {x;H;p;x;P;s/.*//;x}' sasserverstatus.log

great. it worked. can you explain {x;H;p;x;P;s/.*//;x}' – DGaynar Oct 13 '17 at 20:56

You can make the second bracketed sequence a little simpler: `{H;g;p;s/.*//;x}` – Beta Oct 14 '17 at 01:50
You're too kind @Beta that's much better. Thanks! – Ken Schumack Oct 14 '17 at 02:25

With sed :

sed -n '/^he2unix5/h;/NOT up$/{x;G;s/^\n//;p;s/.*//;x}' sasserverstatus.log

Or to keep your look :

sed -n '/^he2unix5/{1bA;s/^/\n/;:A;s/$/\n/;h};/NOT up$/{x;G;p;s/.*//;x}' sasserverstatus.log
