Saving an AWK match
Is it possible to save the result of an AWK match to use later in a BASH script.

Thanks,
Jordon

Hi jhirshon,

Within awk script it could be like this:
Code:
echo "Country
State
City" | awk '/State/{Var=$0;print Var}'
State

Outside awk program, you could store the result of an awk program in a variable $Var and after print its content like this:
Code:
Var=$(echo "Country
State
City" | awk '/State/{print}')
echo "My awk match is" $Var
My awk match is State

Hope it helps.

Thanks cgkml;

I'm trying to save the result from AWK match(s,r) to use later in a script. Should your example work for that?

Thanks again,
Jordon

Hi Jordon,

Yes, a example storing the output of match(s,r) in a variable coud be like this:
Code:
Var=$(echo "How are you?, I hope you are fine" | awk '{print match($0,/hope/)}')
echo "The regex \"hope\" within string begins at position" $Var
The regex "hope" within string begins at position 17

or
Code:
Var=$(echo "How are you?, I hope you are fine" | awk '{print match($0,/hope/),"and its span is",RLENGTH}')
echo "The regex \"hope\" within string begins at position" $Var
The regex "hope" within string begins at position 17 and its span is 4


or
Code:
Var=$(echo "How are you?, I hope you are fine" | 
awk '{match($0,/hope/); print "The regex \"hope\" within string begins at position",RSTART,"and its span is",RLENGTH}')
echo $Var
The regex "hope" within string begins at position 17 and its span is 4

Hope it helps.

Regards
