multiple delimeters in awk

Hi all,

The have 92 columns with combination of "" and , two delimiters‎ and i need to takes some 32 columns only in that. i used awk command to extract .but its not working good.

Example: "aaaa","10,00.00",work,5555,.............

Command i tried :

awk -F"[ ,,"" ]" -v OFS="," 'FNR>1{print $1,$5,$6,$15,$17,$24,$25,$26,$27,$28,$31,$32,$34,$35,$37,$39,$40,$41,$42,$43,$46,$72,$73,$74,$77,$80 ,$81,$82,$84,$88,$90,$92}' >> outfile.csv

I would really appreciate if some one helps as soon as poss

Does the output need to be in the same format (i.e. comma-separated and with quotes preserved)?

Note that this will split the single field "10,00.00" into 10 and 00.00.

Thanks a lot frnds.....

yes Carlom , it it should be preserved with 10,000 not 10 and 000

but sed is not reading multiple files at time


$ sed 's,\",,g' infile*.csv | awk -F, '{ print $1............$92 }' >> outfile.csv

Sorry .. donot have enough time and hence done it in ugly mode ..
for i in `ls infile*.csv`
sed 's,[0-9]\,,&%,g;
  s,\",,g' $i |
awk -F\| '{ print $1............$92 }' >> outfile.csv

This is probably a deeply inelegant way of doing it, but it's just a quickie from some other code I had lying around (that I probably copied from somewhere else!).

#  cat csv2.awk
        if (NUMCOLS == "") NUMCOLS=32
        if (DELIM == "") DELIM = "\t"
        if (REPL == "") REPL = "~"
        gsub(DELIM, REPL)
        $0 = gensub(/([^,])\"\"/, "\\1'", "g")
        out = ""
        n = length($0)
        for (i = 1;  i <= n;  i++) {
                if ((ch = substr($0, i, 1)) == "\"") {
                        inString = (inString) ? 0 : 1
                out = out ((ch == "," && ! inString) ? DELIM : ch)
        for (i=1;(i<=nfields)&&(i<=NUMCOLS);i++) {
                if (i > 1) {
                        printf (",");
                printf ("%s", outfields[i]);
        printf ("\n");

#  cat a.csv

# awk -f csv2.awk a.csv

(it will fail if there are any tabs in the data, but you can change the delimiter to something else if need be)
