Shell Programming and Scripting
1

Hi,
Iam a novice to unix shell scripting, need a help from you guys.The scenario is as follows, i have the following Text file.

order No    Company    Category
21    aaa    A
24    aaa    A
87    aaa    B
98    aaa    B
23    abc    A
45    abc    B
25    bbb    A
76    wes    A
66    wes    B
44    wes    B
35    wes    B
39    wes    B
90    esd    B
99    esd    B
109    esd    B
26    esd    B
58    esd    A
76    tre    B
75    tre    B

Desired Output is as follows(columns Count, A, B are the no of times they are repeated):

Company    Count    A    B
aaa    4    2    2
abc    2    1    1
bbb    1    1    0
wes    5    1    4
esd    5    4    1
tre    2    0    2

The output should be in a different file. Appreciate your help.

Hi,

awk '/^[0-9]/ { print $2,$3}' input-file | sort | uniq -c | awk 'BEGIN{print "Company    Count   A   B"} {if (comp && comp != $2) { printf("%-10s %5d %3d %3d\n",comp,a["A"]+a["B"],a["A"],a["B"]); comp=""; a["A"]=a["B"]=0; } comp=$2; a[$3]=$1; } END{if (comp) printf("%-10s %5d %3d %3d\n",comp,a["A"]+a["B"],a["A"],a["B"]);}'

That's a one-liner in name only. In the future, please use a reasonable coding style instead of such a long line. It will make your code easier for novices to understand, and members not using a 2560 pixel wide display will be able to read your post (and posts which quote your post) without having to resort to tedious horizontal scrolling.

Hi,

Alister you are right, even if this solve the problem it's not user friendly, so here is the readable version :slight_smile:

First take only company name and the A/B status and we sort them

# awk '/^[0-9]/ { print $2,$3}' input-file | sort > sorted-file

Then we process the sorted-file by counting duplicates and re-arrange output

# uniq -c sorted-file | awk -f doit.awk
Company    Count   A   B
aaa            4   2   2
abc            2   1   1
bbb            1   1   0
esd            5   1   4
tre            2   0   2
wes            5   1   4

here is the content of the file doit.awk :

BEGIN { 
  print "Company    Count   A   B"
}

{
  if (comp && comp != $2) {
    printf("%-10s %5d %3d %3d\n",comp,a["A"]+a["B"],a["A"],a["B"]);
    comp="";
    a["A"]=a["B"]=0;
  }
  comp=$2;
  a[$3]=$1;
}

END {
  if (comp) printf("%-10s %5d %3d %3d\n",comp,a["A"]+a["B"],a["A"],a["B"]);
}

Hi,

Try this one,
Shorter version of untested code,

awk '/^[0-9]/ {a[$2]=a[$2]+1;b[$2" "$3]=b[$2" "$3]+1;}END{print"Company    Count   A   B"; for(i in a){printf("%-10s %5d %3d%3d\n",i,a,b[i" A"],b[i" B"]);}}' inputfile

if you have GNU awk you can sort the array a using asort function.

Well done Ranga :slight_smile:

ps for fun :

awk '/^[0-9]/ {a[$2]++;b[$2" "$3]++;}END . . . .
