Shell Programming and Scripting

Hi,

i have used awk command to find a particular field from the file using filter.

The problem is that i am getting the field in a variable, however i m not able to use that variable in other part of the script.
Here is a code:

............
Some script...
........
awk -F" " '/filter/ { var1 = $3 }' /usr/tmp/file.txt

# this is i want to do but i m not able to do that
if [ $var1 == 5 ]; then
echo $var1
fi

..............
Some script
..............

Here is the format of the file:
a filter 1
a filter 3
a filter 4
a filter 5
a user 1
a user 4
a user 5


Can you suggest some solution so that I can get particulat field in some variable and do some processing?

Get back to me if you need any more clarification about the problem.

Thanks,

Why you cant do the if command?
are u getting an error? if so what is the error?
did you tried it like that:

if [ $var1 -eq 5 ]; then
echo $var1
fi

If it still not working
try to put echo $var1 before the if, and check that u get an integer

Yes, it is not working..even if I put that before the "if"

it seems var1 is not holding up the value.. when i try to print var1 in awk it prints but not after the awk

is there any alternative to get the value of var1 and use in the script at some other place..i want to do this as i have to make decision based on the value of var1.

Ok, I take the line u wrote and try to run it on my server,
U actually not enter anything to var1 and thats why the if fails,

Try to do it like that:

var1=`awk -F" " '/filter/ {print $3}' /usr/tmp/file.txt

Now, var1 will holds the whole field #3 from all the lines, so if u do
echo $var 1
u will get somthing like:
1 3 5 2 6 ..... etc,
I know that's not what u want.
I just gave u the basic of how to get this parameter into var1,
now what u have to do is to create a loop that will run on all over the file and each time will take only one line into var1,

Or,
u can keep the var1 with all the values from file.txt and create a loop that will run on all values in var1.

Thanks much..
