awk 2 delimiter nested Problem

Hello All, This work could be very easy for you guys. I would really appreciate help.

input file:
aa|bb|cc|dd,ee ff,xx|gg,zz|hh,bv
pp|qq|rr|ss,tt uu,yy|vv,xc|ww,mn
output file: (Desired)
num=aa value=bb digits=cc name1=dd:link1=ee name2:ff:link2=xx file=gg:link=zz code=hh:link=bv
num=ii value=jj digits=kk name1=ll:link1=mm file=nn:link=as code=oo:link=lk
num=pp value=qq digits=rr name1=ss:link1=tt name2=uu:link2=yy file=vv:link=xc code=ww:link=mn
What I am capable of doing:
Command: cat inputfile | awk -F\| '{print "num="$1" value="$2" digits="$3" name1="$4" file="$5" code="$6}' > outputfile

Result what I am capable of getting:
num=aa value=bb digits=cc name1=dd,ee ff,xx file=gg,zz code=hh,bv
num=ii value=jj digits=kk name1=ll,mm file=nn,as code=oo,lk
num=pp value=qq digits=rr name1=ss,tt uu,yy file=vv,xc code=ww,mn
As per my understanding some tricks to that command is needed to involve nested 2 delimiters (i.e. "|" & "," & " "(space) chracter). I dont have any idea how to go about it. Could anyone solve this thing for me or give me some diff logic to acheive this desired output file.

I would really appreciate if some one helps as soon as poss. Thanks a lot people. Smilie

With a modern awk (nawk, gawk, etc), FS (field separator) can be any regular expression.
including a backslash. For example

FS = "[;:\\\\]"


";" ":" "\"

(The brackets "[" and "]" are part of the regular expression syntax)

I knw that. I myself have used "|" as delimiter. My problem here is to use 2 delimiters in order to get desired output file.

I need outputfile from inputfile by some trick.

Thanks for replying.Smilie

Please try this one. On my pc it is ok.

awk 'BEGIN{FS="|"}
printf("num=%s value=%s digits=%s ",$1,$2,$3)
n=split($4,arr," ");
for (i=1;i<=n;i++)
	printf("name%d=%s:link%d=%s ",i,brr[1],i,brr[2])
printf("file=%s:link=%s ",crr[1],crr[2])
}' a
