Awk: Error with END
Hello,

I can't understand why there's an error with End with simple code.

Data:
Code:
rs10458597 1:564621
rs2185539 1:566875
rs11240767 1:728951
rs12564807 1:734462
rs3131972 1:752721
rs3131969 1:754182
rs3131967 1:754334

Code:
awk ' {
if(!snp[$2]){
snp[$2] = $0
}
else{
snp[$2] = snp[$2] $0 " "
}

END
{
print "awa"
}

}
 ' new_id.txt

Error:

Code:
awk: cmd. line:9: END
awk: cmd. line:9: ^ syntax error

Please guide me fix this.

There's an error in the sequence of opening and closing braces.

Thanks for your reply.

Code:
awk ' 

{
if(!snp[$2]){ snp[$2] = $0 
cnt[$2]++
arr[++SN]=$2
}
else{ snp[$2] = snp[$2] " " $0 " " 
cnt[$2]++
}
}
END { 
for( i in snp){
if(cnt[i] == 2){
print i,snp[i]
}
}
}


 ' new_id.txt

Fixed it. Smilie

Braces out of place. The END section will not execute. try:
Code:
awk '
{ if(!snp[$2]) {
      snp[$2] = $0
   } else {
      snp[$2] = snp[$2] $0 " "
   }
}

END {
   print "awa"
}
 ' new_id.txt

Yes, and the indention improves readability!

Normally you should test for existence if (!($2 in snp))
and not for a zero/empty value if (!snp[$2])
