All,

Here is what I am searching for using sed.

1 00640000106798

I want to replace that with the following.

8 0064B0000106798

I can do this easy enough from the command line using sed but I need to put the search string in a file and then execute the sed command within a shell script. I think the problem has something to do with how the spaces are being evaluated when reading from the file as the search string is never being found. Here is what I have so far. Please Help!!

cat $1 | while read LINE
do
echo $LINE > LINE.out

firstVar=$(awk -F" " '{print $1}' LINE.out)
secondVar=$(awk -F" " '{print $2}' LINE.out)
space=" "

testVar=${firstVar}$space${secondVar} #This makes the string 1 00640000106798

When I execute the following line the search string is never found.


sed 's/"$testVar"/8 0064B0000106798/g' WhatIf_4_Forecast.dat > tester.dat

sed "s/"$testVar"/8 0064B0000106798/g" WhatIf_4_Forecast.dat > tester.dat

And drop the double quotes surrounding $testVar
