AWK help

Hi,
I have a file with the following data in a file :: File1

Code:
Name Credit
A       45
B       4
D       9
A       -3
B       -10
A       -3

Need the output as

Code:
Name  +ve Cr    -ve Cr
A        45            -6
B        4              -10
D        9               0

Got a command that adds up all the records but without segregating +ve and -ve values.

Code:
awk -F"," '{a[$2]+=$1}END{for (i in a) print i,a[i]}' file1

Please assist.

Thanks and Regards,
Gideon.

You need to use some conditional statements. I would do all this in just 1 line of code because it would look messy.

Well that was not very constructive.

Here you go:
Code:
awk '
NR==1{ printf("%20s\t%10s\t%10s\n", $1,"+ve Cr","-ve Cr")}
NR>1{ if($2>0) sumPos[$1] += $2; 
      else     sumNeg[$1] += $2; 
      aux[$1]}
END{for(i in aux) printf("%20s\t%10d\t%10d\n", i, sumPos[i]?sumPos[i]:0, sumNeg[i]?sumNeg[i]:0)}' infile

Awesome. My actual file was "," delimited. I added a -F",". Thanks a lot again.

Hi and welcome to the forum. Next time, please start your own thread, do not post your unrelated question on someone else's. And please use code tags around any input, output and code. Thanks.

Now to your problem -- I'm not sure I understand what you mean. It is always helpful to see what you want to get also -- your desired output. If you want to insert a line before every string '6218', then you could use this:

Code:
sed '/6218/ i My line goes here' file

hi, thanks for the help but it is not working.
It is giving the error message "sed: command garbled:"
