Bash script that analyzes report files

Question

I have the following bash script which I will use to analyze all report files in the current directory:

#!/bin/bash    


# methods
analyzeStructuralErrors()
{ 
         


        

Answer 1

Bash has one-dimensional arrays that are indexed by integers. Bash 4 adds associative arrays. That's it for data structures. AWK has one dimensional associative arrays and fakes its way through two dimensional arrays. If you need some kind of data structure more advanced than that, you'll need to use Python, for example, or some other language.

That said, here's a rough outline of how you might parse the data you've shown.

#!/bin/bash    

# methods
analyzeStructuralErrors()
{ 
    local f=$1
    local Xpat="Error Code for Issue X"
    local notXpat="Error Code for Issue [^X]"
    while read -r line
    do
        if [[ $line =~ $Xpat ]]
        then
            flag=true
        elif [[ $line =~ $notXpat ]]
        then
            flag=false
        elif $flag && [[ $line =~ , ]]
        then
            # columns could be overwritten if there are more than one X section
            IFS=, read -ra columns <<< "$line"
        elif $flag && [[ $line =~ - ]]
        then
            issues+=(line)
        else
            echo "unrecognized data line"
            echo "$line"
        fi
    done

    for issue in ${issues[@]}
    do
        IFS=- read -ra array <<< "$line"
        # do something with ${array[0]}, ${array[1]}, etc.
        # or iterate
        for field in ${array[@]}
        do
            # do something with $field
        done
    done
}

# main
find . -name "*_report*.txt" | while read -r f
do
    echo "Processing $f"
    analyzeStructuralErrors "$f"
done
