AWK syntax question

Leo_NN · #1 (**permalink**) 10-27-2008

Hi,

Have to check file names in some given directory.

SO, What is the right syntax here:

Quote:

>object_list="CUSTOMER ADDRESS TELEPHONE"
>file_list=`ls $DATA_PATH | awk -F"_" 'NF==5 && $1=="'$vendor'" && $2=="'$source'" && *$3*=="'$object_list'" {print $0}'`

*$3*=="'$object_list'" - just wanted to check if $3 is in the object_list.

And also, Do I need so many quotes around?

why are you using * around $3 ?

The syntax is correct if you remove the * like

Code:

file_list=`ls $DATA_PATH | awk -F"_" 'NF==5 && $1=="'$vendor'" && $2=="'$source'" && $3=="'$object_list'" {print $0}'`

object_list="CUSTOMER ADDRESS TELEPHONE"

Here I wanted to check if $3 is in the object_list, not equal, but part of it.
For instance if $3="CUSTOMER" - OK.
So I need something like IN or *$3* syntax, I think.

thanks.

To the OP: use ~ for contains rather than == (use nawk / /usr/xpg4/bin/awk on solaris)

To the thread hijacker ;-) , shruthinagaraj, go to a particular forum where you wish to post - in the top left is a "start new thread" button...

Is it ok to do it that way:

I can't do:

Quote:

awk '... $object_list ~ $3 ...'

But I can

Quote:

awk '... $3~$object_list...'

for some reasons?
