awk using env variable as search argument
Hello,
I have a file like

Code:
was123##abcdefg abddef
was123##xuzaghg agdfgg
was133##CGHAKS DKGJG

from the file i need to print the line after ## where the serach value is passed by an env variable called luster (which is currently set to was123):



i tried using the below code but it does not work

Code:
>echo $luster
>was123
>nawk -v var=$luster '/luster/ {  print $2}' checkNewWebsphereErr.data
>

is there any other way to do that ?

Try this:

Code:
nawk -F"#" -v var=$luster '/luster/ {print $NF}' checkNewWebsphereErr.data

didn't you mean this:
Code:
nawk -F"#" -v var=$luster '$0 ~ var {print $NF}' checkNewWebsphereErr.data

That's what I mean. Smilie

Thanks!

passing variables into awk is a valuable trick -- although not necessary here:

Code:
awk '/##'$luster/ checkNewWebsphereErr.data

.... works fine.

too cumbersome involving jumping back and forth from awk to shell and back, harder to read as well - I don't like this paradigm.
Just my $.02

okay -- how about this:

Code:
fgrep '##'$luster file

all unix and shell.
