i have a file - it will be in sorted order on column 1
abc 0 1
abc 2 3
abc 3 5
def 1 7
def 0 1

i'd like (awk maybe?) to get the results (any ideas)???
abc 5 9

The awk needed....if coloumn 9 == i (coloumn 9 is string ), output the sum of x's(coloumn 22 ) in all records and sum of y's (coloumn 23 ) in all records in a file (records.txt).... (6 Replies)
cat sample.csv
ID,Name,no
1,AAA,1
2,BBB,1
3,AAA,1
4,BBB,1
cut -d',' -f2 sample.csv | sort | uniq
this gives only the 2nd column values
Name
AAA
BBB
How to I get all the columns of CSV along with this? (1 Reply)
Hi,
I have a requirement where in I need to insert delimiters before the last column of the total delimiters is less than a specified number.
Say if the delimiters is less than 139, I need to insert 2 columns ( with blanks) before the last field
awk -F 'Ç' '{ if (NF-1 < 139)} END { "Insert 2... (5 Replies)
Hi,
I have a text file 'Item_List.txt' containing only 1 column. This column lists different products, each separated by the same generic string header "NEW PRODUCT, VERSION 1.1". After this the name of the product is given, then a delimiter string "PRODUCT FIELD", and then the name of the... (11 Replies)

Hi all,
I've multiple files. In this case 5. Space separated columns. Each file has 12 columns. Each file has 300-400K lines.
I want to get the output such that if a value in column 2 is present in all the files then get all the columns of that value and print it side by side.
Desired output... (15 Replies)

rs
RS(1) BSD General Commands Manual RS(1)NAME
rs -- reshape a data array
SYNOPSIS
rs [-[csCS][x] [kKgGw][N] tTeEnyjhHmz] [rows [cols]]
DESCRIPTION
The rs utility reads the standard input, interpreting each line as a row of blank-separated entries in an array, transforms the array accord-
ing to the options, and writes it on the standard output. With no arguments it transforms stream input into a columnar format convenient for
terminal viewing.
The shape of the input array is deduced from the number of lines and the number of columns on the first line. If that shape is inconvenient,
a more useful one might be obtained by skipping some of the input with the -k option. Other options control interpretation of the input col-
umns.
The shape of the output array is influenced by the rows and cols specifications, which should be positive integers. If only one of them is a
positive integer, rs computes a value for the other which will accommodate all of the data. When necessary, missing data are supplied in a
manner specified by the options and surplus data are deleted. There are options to control presentation of the output columns, including
transposition of the rows and columns.
The following options are available:
-cx Input columns are delimited by the single character x. A missing x is taken to be `^I'.
-sx Like -c, but maximal strings of x are delimiters.
-Cx Output columns are delimited by the single character x. A missing x is taken to be `^I'.
-Sx Like -C, but padded strings of x are delimiters.
-t Fill in the rows of the output array using the columns of the input array, that is, transpose the input while honoring any rows and
cols specifications.
-T Print the pure transpose of the input, ignoring any rows or cols specification.
-kN Ignore the first N lines of input.
-KN Like -k, but print the ignored lines.
-gN The gutter width (inter-column space), normally 2, is taken to be N.
-GN The gutter width has N percent of the maximum column width added to it.
-e Consider each line of input as an array entry.
-n On lines having fewer entries than the first line, use null entries to pad out the line. Normally, missing entries are taken from
the next line of input.
-y If there are too few entries to make up the output dimensions, pad the output by recycling the input from the beginning. Normally,
the output is padded with blanks.
-h Print the shape of the input array and do nothing else. The shape is just the number of lines and the number of entries on the first
line.
-H Like -h, but also print the length of each line.
-j Right adjust entries within columns.
-wN The width of the display, normally 80, is taken to be the positive integer N.
-m Do not trim excess delimiters from the ends of the output array.
-z Adapt column widths to fit the largest entries appearing in them.
With no arguments, rs transposes its input, and assumes one array entry per input line unless the first non-ignored line is longer than the
display width. Option letters which take numerical arguments interpret a missing number as zero unless otherwise indicated.
EXAMPLES
The rs utility can be used as a filter to convert the stream output of certain programs (e.g., spell, du, file, look, nm, who, and wc(1))
into a convenient ``window'' format, as in
% who | rs
This function has been incorporated into the ls(1) program, though for most programs with similar output rs suffices.
To convert stream input into vector output and back again, use
% rs 1 0 | rs 0 1
A 10 by 10 array of random numbers from 1 to 100 and its transpose can be generated with
% jot -r 100 | rs 10 10 | tee array | rs -T > tarray
In the editor vi(1), a file consisting of a multi-line vector with 9 elements per line can undergo insertions and deletions, and then be
neatly reshaped into 9 columns with
:1,$!rs 0 9
Finally, to sort a database by the first line of each 4-line field, try
% rs -eC 0 4 | sort | rs -c 0 1
SEE ALSO jot(1), pr(1), sort(1), vi(1)BUGS
Handles only two dimensional arrays.
The algorithm currently reads the whole file into memory, so files that do not fit in memory will not be reshaped.
Fields cannot be defined yet on character positions.
Re-ordering of columns is not yet possible.
There are too many options.
