eine Spalte zu csv Hinzufügen und + awk tun Division

das ist meine Dateieine Spalte zu csv Hinzufügen und + awk tun Division

$ cat test1 
"Rec_Open_Date","MSISDN","IMEI","Data_Volume_Bytes","Device_Manufacturer","Device_Model","Product_Description" 
"2015-10-06","427","060","137765","Samsung Korea","Samsung SM-G900I","$39 Plan"

"2015-10-06","556","910","13332272","Samsung Korea","Samsung GT-I9505","$49 Plan"

dieser Befehl an das Ende einer Spalte hinzufügt.

$ awk -F"," 'BEGIN { OFS = "," } {$7=($4); print}' test1 
"Rec_Open_Date","MSISDN","IMEI","Data_Volume_Bytes","Device_Manufacturer","Device_Model","Data_Volume_Bytes" 
"2015-10-06","427","060","137765","Samsung Korea","Samsung SM-G900I","137765" 
"2015-10-06","592","620","0","Apple Inc","Apple iPhone 6 (A1586)","0"

wie bekomme ich die folgende Ausgabe: Der Einfachheit halber dies nur $7=($4/1) ist.

"Rec_Open_Date","MSISDN","IMEI","Data_Volume_Bytes","Device_Manufacturer","Device_Model","Data_Volume_Bytes" 
    "2015-10-06","427","060","137765","Samsung Korea","Samsung SM-G900I","137765" 
    "2015-10-06","592","620","0","Apple Inc","Apple iPhone 6 (A1586)","0"

Was wirklich tun möchte, der Lage sein, ich ist $7=$4/10124/1024 aber aus irgendeinem Grund kann ich nicht die Division an die Arbeit.

Ich habe das versucht, aber ich bekomme nur $ 7 = gleich Null.

awk -F"," 'BEGIN { OFS = "," } {$7=($4/1024); print}' test1 
"Rec_Open_Date","MSISDN","IMEI","Data_Volume_Bytes","Device_Manufacturer","Device_Model",0 
"2015-10-06","427","060","137765","Samsung Korea","Samsung SM-G900I",0

EDIT1: Thsi ist, wie ich den Namen des Spalts Kopfes in Spalte 7. Nicht sicher ändern, wenn \" ist die beste oder einzige Möglichkeit, es in doppelten Anführungszeichen zu halten.

$ awk -F"," '{ OFS = "," } NR<=1{$7="\"Data_Volume_MB\""; print}' test1 
"Rec_Open_Date","MSISDN","IMEI","Data_Volume_Bytes","Device_Manufacturer","Device_Model","Data_Volume_MB"

EDIT2 DIES IST, was ich will, aber es geht casting from a string to an int in awksubstr($4,2,(length($4)-2)). aber die Antwort ist nicht in Anführungszeichen 0.131383, für Einheitlichkeit wie erreiche ich das?

$ awk -F"," '{ OFS = "," } NR>1{$7=substr($4,2,(length($4)-2))/1024/1024; print}' test1 
"2015-10-06","427","060","137765","Samsung Korea","Samsung SM-G900I",0.131383 
"2015-10-06","592","620","0","Apple Inc","Apple iPhone 6 (A1586)",0 
"2015-10-06","007","290","0","Apple Inc","Apple iPhone 6 (A1586)",0 
"2015-10-06","592","050","48836832","Apple Inc","Apple iPhone 5S (A1530)",46.5744

Dies ist das Problem, weil meine Werte in Anführungszeichen "137765" eingeschlossen sind. – HattrickNZ

Ich würde vorschlagen, nach etwas wie Python oder Ruby zu greifen, das einen tatsächlichen CSV-Parser hat, der weiß, wie man korrekt mit zitierten Werten umgeht, oder vielleicht etwas wie das [csv-Befehlszeilentool] (https://github.com/gaal/ app-csv). – larsks

Sie sind auf dem richtigen Weg, nur ein paar kleinere Probleme

$ awk -F, -v OFS=, -v q='"' 'NR==1{$7=q"Data_Volume_MB"q} 
       NR>1{$7=$4; gsub(/"/,"",$7); $7= q $7/(1024*1024)q}1' file

"2015-10-06","556","910","13332272","Samsung Korea","Samsung GT-I9505","12.7146"'

-v q='"' definieren eine Variable anstelle der Anführungszeichen

gsub(/"/,"",$7) Entfernen von Flucht zitiert

$7= q $7/(1024*1024)q tun die Division und fügen Sie Angebote zurück
