Hi can anyone assist me on my problem.
I try to grep 1 word in 1 line data. Example like below.

* Data below located in a.txt, i just wanna grep just processing-time = "12"

total-octets = "20080718214210Z" total-pages = "" octets-completed = "20080721064351Z" pages-completed = "2" processing-time = "12"

I searched the threat and found 1 solution like below, unfortunately it is just work if the word located in different row not in 1 line row.

sed -ne '/^[ ]*processing-time/s#^$[^=][^=]*$=$[^/][^/]*$.*#\12#p'

You may get something useful from piping Your search through sed this way:

Code:

echo 'total-octets = "20080718214210Z" total-pages = "" octets-completed = "20080721064351Z" pages-completed = "2" processing-time = "12"'|sed -e 's/ = /=/g;s/ /\n/g'

resulting in

Code:

total-octets="20080718214210Z"
total-pages=""
octets-completed="20080721064351Z"
pages-completed="2"
processing-time="12"

which then can be used in a script or something...

Hi Lakris,

I tried to used your method using the pipe after the echo but it wouldn't work. Sorry if it is my mistake i am new in this shell field. Below is what i did

My Code :

Quote:

$ test=`cat file1.txt`
$ echo $test|sed -e 's/ = /=/g;s/ /\n/g'

Result I get :

Quote:

total-octets="20080718214210Z"ntotal-pages=""noctets-completed="20080721064351Z"npages-completed="2"nprocessing-time="12

If your code are working means i can just sort it more cleanly using row, as the usefull output data.
