Concatenating multiple lines to one line if match pattern - Shell Programming and Scripting

phixsius · #1 01-24-2008

Hi all,

I've been working on a script which I have hit a road block now. I have written a script using sed to extract the below data and pumped into another file:

Severity............: MAJORWARNING
Summary:
System temperature is out of normal range.
Severity............: MAJORWARNING
Summary:
Adapter at hardware path 0/4/1/0 : Received an interrupt indicating and
Elastic Store Error Storm
Severity............: MAJORWARNING
Summary:
Adapter at hardware path 0/3/1/0 : Received an interrupt indicating and
Elastic Store Error Storm
Severity............: MAJORWARNING
Summary:
System temperature is out of normal range.

I want to format it to look like this:
"Severity:.......... Summary:........"
"Severity:.......... Summary:........"
"Severity:.......... Summary:........"
"Severity:.......... Summary:........"

so that each ocurance will be in one line

Any ideas? Hope someone can help me quickly.

Thanks
phixsius.

With GNU Awk:

Code:

awk 'NF&&$1=RS$1'  RS="Severity" filename

Hi radoulov,

I ran the line, however this was the output:

Severityeverity............: MAJORWARNING
Severityummary: Adapter at hardware path 0/3/1/0 : Received an interrupt indicating and Elastic
Severitytore Error
Severitytorm
Severityeverity............: MAJORWARNING
Severityummary: Adapter at hardware path 0/4/1/0 : Received an interrupt indicating and Elastic
Severitytore Error
Severitytorm
Severityeverity............: MAJORWARNING
Severityummary:
Severityystem temperature is out of normal range.

I said GNU Awk ...

Given your sample this should work with non-Gnu Awk:

Code:

awk 'ORS=/:/?FS:RS' filename

Use nawk or /usr/xpg4/bin/awk on Solaris.

Hey mate,

Thanks alot for your suggestions. Unfort, i'm sorry, its still doesnt produce the result I'm looking...

Think there are any other logics to achieving this?

Code:

sed -n '
:a
/Sev/ {
N
/Sev.*Sev/ !{
s/\n/ /
ta
}
P
D
}' infile

is probably close :-)
