I for the most part understand whats happening here. Could you explain the purpose of the ":0:5" in this line? I found what the curly brackets do, but as of yet, not the colons.
Code:
 if [ "${LINE:0:5}" = "data7" ]

it extracts 5 characters from position 0 (the first)

The only problem i'm having is that it's deleting the line that contains "SystemDeclarationData". otherwise it's working great. can you tell me what i'm doing wrong?
The script is wrong i'll modify it to work properly.
In a couple of minutes, OK?Smilie
The script
Code:
#!/bin/bash
Input="test.fplan"
I=1
while read LINE
do    #~ find the string that starts with data7
    echo "$LINE"
    [ "${LINE:0:5}" =~ "SystemDeclarationData" ] || continue #~ continue if the condition is not satisfied
    read LINE
    if $(echo "$LINE" | grep -q prisoner)
    then    head -n$I $Input | tail -n1
        (( I ++ ))
    else echo "$LINE"
    fi
done < $Input > test_csv.csv
