But is there a way to do it disregarding the first column values.
If you want to disregard the first column, just print the sum:

By default, the order in which a for (i in array) loop scans an array is not defined; it is generally based upon the internal implementation of arrays inside awk.
You might have to use an indexed array to preserve the order.
HI ALL,
i have a problem when i do a sort sum with many fields.
Is there a limit for fields?
Do you know a solution?
thanks in advance.
the shell is:
# SORT1
SORT1_rcode=777
if ; then
echo "USE $DARSEQ/OTPU.FTPEPREC RECORD F,1000 " > $DARPARSRT/TPEKL508.SORT1_$$.srt

Hey,
I have a file and it has only one field. I need to calculate the sum of each filed as total.
For e.g my file is
1
2
3
4
5
I need to calculate the total sum as 15.
Please let me know how i can do it? (4 Replies)
Hi unix gurus,
I have a urgent requirement, I need to write a AWK script to compare each fields in 2 files using AWK.
Basically my output should be like this.
file1
row|num1|num2|num3
1|one|two|three
2|one|two|three
file2
row|num1|num2|num3
1|one|two|three
2|one|two|four

I use the two awk scripts for comparing file1 and file2.
First awk compare $3 column:
awk -v OFS="\t" 'NR==FNR{a=$4;next}{$2=$2 "\t"(a?a:"-")}1' file1 file2Second awk compare $2 column:
awk -v OFS="\t" 'NR==FNR{a=$4;next}{$2=$2 "\t"(a?a:"-")}1' file1 file2 The only difference

In the awk below I am trying to add a penalty to a score to each matching $1 in file2 based on the sum of $3+$4 (variable TL) from file1. Then the $4 value in file1 is divided by TL and multiplied by 100 (this valvue is variable S). Finally, $2 in file2 - S gives the updated $2 result in file2.... (2 Replies)
Hi, I have two TEST files t.xyz and a.xyz which have three columns each. a.xyz have more rows than t.xyz. I will like to output rows at which $1 and $2 of t.xyz match $1 and $2 of a.xyz. Total number of output rows should be equal to that of t.xyz.
It works fine, but when I apply it to large... (6 Replies)

join
JOIN(1) BSD General Commands Manual JOIN(1)NAME
join -- relational database operator
SYNOPSIS
join [-a file_number | -v file_number] [-e string] [-o list] [-t char] [-1 field] [-2 field] file1 file2
DESCRIPTION
The join utility performs an ``equality join'' on the specified files and writes the result to the standard output. The ``join field'' is
the field in each file by which the files are compared. The first field in each line is used by default. There is one line in the output
for each pair of lines in file1 and file2 which have identical join fields. Each output line consists of the join field, the remaining
fields from file1 and then the remaining fields from file2.
The default field separators are tab and space characters. In this case, multiple tabs and spaces count as a single field separator, and
leading tabs and spaces are ignored. The default output field separator is a single space character.
Many of the options use file and field numbers. Both file numbers and field numbers are 1 based, i.e., the first file on the command line is
file number 1 and the first field is field number 1. The following options are available:
-a file_number
In addition to the default output, produce a line for each unpairable line in file file_number.
-e string
Replace empty output fields with string.
-o list
The -o option specifies the fields that will be output from each file for each line with matching join fields. Each element of list
has the either the form 'file_number.field', where file_number is a file number and field is a field number, or the form '0' (zero),
representing the join field. The elements of list must be either comma (',') or whitespace separated. (The latter requires quoting
to protect it from the shell, or, a simpler approach is to use multiple -o options.)
-t char
Use character char as a field delimiter for both input and output. Every occurrence of char in a line is significant.
-v file_number
Do not display the default output, but display a line for each unpairable line in file file_number. The options -v 1 and -v 2 may be
specified at the same time.
-1 field
Join on the field'th field of file 1.
-2 field
Join on the field'th field of file 2.
When the default field delimiter characters are used, the files to be joined should be ordered in the collating sequence of sort(1), using
the -b option, on the fields on which they are to be joined, otherwise join may not report all field matches. When the field delimiter char-
acters are specified by the -t option, the collating sequence should be the same as sort(1) without the -b option.
If one of the arguments file1 or file2 is ``-'', the standard input is used.
EXIT STATUS
The join utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITY
For compatibility with historic versions of join, the following options are available:
-a In addition to the default output, produce a line for each unpairable line in both file 1 and file 2.
-j1 field
Join on the field'th field of file 1.
-j2 field
Join on the field'th field of file 2.
-j field
Join on the field'th field of both file 1 and file 2.
-o list ...
Historical implementations of join permitted multiple arguments to the -o option. These arguments were of the form
'file_number.field_number' as described for the current -o option. This has obvious difficulties in the presence of files named
'1.2'.
These options are available only so historic shell scripts do not require modification. They should not be used in new code.
LEGACY DESCRIPTION
The -e option causes a specified string to be substituted into empty fields, even if they are in the middle of a line. In legacy mode, the
substitution only takes place at the end of a line.
Only documented options are allowed. In legacy mode, some obsolete options are re-written into current options.
For more information about legacy mode, see compat(5).

The join command conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
