Testing success of AWK code in KSH script
I need a bit of help here on something simple. I have a KSH script (must be KSH) that needs to change 2 positional variables in a CSV script. The CSV script looks like this: 00001,010109,01/01/2009 00:01:01 00008,090509,09/05/2009 13:47:26 My AWK script will change $2 and $3 based on the value of $1. The values in $1 are distinct and must match to one of the values in the first column with every call to this script. Code:
cat csv_file.csv | awk 'BEGIN {FS=","; OFS=FS}
{
if($1 == one) {
$2 = two
$3 = three
}
print
}' one="${one}" two="${two}" three="${three}" > tmp_file.csv
So far it works fine. What I'm wondering how to do is to test if the AWK code successfully completed. If I call $? I always get a status of 0 (since the cat does work fine). How do I verify that the AWK code did not error out? |
