Egrep output
If I have an output from egrep that has two elements on separate lines can I concatenate them? so the egrep for examople might be:

Code:
egrep "filename|type"

And the actual output might be:

Code:
./file001.doc
Type Text Document

How do I get the egrep to remove the line feed so the output is:

Code:
./file001.doc Type Text Document

???
Thanks in advance.

Hello TuftyDave,

Request you to show sample Input_file with expected output sample. Could you please try following(not tested though) and let me know if this helps you.
Code:
awk '/filename/ || /type/{A=A?A OFS $0:$0;} /type/ && A{print A;A=""}' Input_file

Thanks,
R. Singh

Hi Ravinder

I really wanted to know if there is a solution to this using egrep, as my inout is via find....
I understand that ASCII 08 or ^H is the backspace character, I was hoping to find out how to integrate that into the egrep output parameter...

This is one I was doing a couple of days ago, but the issue is the same...

From this one, I want the filename & the Camera Model to be o/p on the same line...
what I used is:
Code:
find -iname "*.jpg" -print0 | xargs -0 exiftool -a | egrep "===|Camera Model Name"

What it gives me is:
Code:
======== ./20150608_142304.jpg
Camera Model Name               : GT-I9100
======== ./20150608_142308.jpg
Camera Model Name               : GT-I9100
======== ./20150608_154859.jpg
Camera Model Name               : GT-I9100
======== ./20150610_090355.jpg
Camera Model Name               : GT-I9100
.... (etc)

What I want is:

Code:
======== ./20150608_142304.jpg Camera Model Name               : GT-I9100
======== ./20150608_142308.jpg Camera Model Name               : GT-I9100
======== ./20150608_154859.jpg Camera Model Name               : GT-I9100
======== ./20150610_090355.jpg Camera Model Name               : GT-I9100

So I want to modify the egrep op somehow to loose the line feed.

You can't change the output format of egrep using egrep, although if you could directly grep the files instead of reformatting them using exiftool, you could just use:
Code:
fgrep 'Camera Model Name' /dev/null *.jpg

to print the lines containing Camera Model Name preceded by the name of the file that contained that line.

But you can use another filter to join lines together at the end of your current pipeline. For example:
Code:
find -iname "*.jpg" -print0 | xargs -0 exiftool -a | egrep "===|Camera Model Name" | paste -d ' ' - -

or you could replace the egrep with something that can select the desired lines and do some reformatting similar to what Ravinder was suggesting:
Code:
find -iname "*.jpg" -print0 | xargs -0 exiftool -a | awk '/===/{printf("%s ",$0)}/Camera Model Name/'
