I have a file which looks like:
I want to print the entire row in which 5th column is having minimum value for every first column (i.e min for 9 and min for 16). Along with the condition awk -F" " 'b < $5 {b=$5; a=$0} END {for (i in a) {print a}}' inputfile >... (1 Reply)

Hi All,
My Input.txt should have always 4 columns in some cases i may not get all the 4columns data.
My requirement is if columns as not equal to 4 then append new column delimiter.

C,1
Desired output should be in below format

Hey everyone,
I have an issue with a client that is passing me a list of values in one column, and occasionally the combination of all the values results in more than an 255 character string. My DB has a 255 character limit, so I am looking to take the column (comma delimited file), and if it... (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 all
I need to count files on a daily basis and send the output via email, what I am currently doing its simply running the following:ls -lrt *.cdr | awk '{if(($6 == "Jul") && ($7 == "13")) print $0}' | wc -l, which in this case it will count all files with extension "cdr" from the month of...

Hi Experts,
Need your support
I want to group/concatenate column 1,2,12 and 13 and if found duplicate then need to sum value of column 17,20,21 and column22. After concatenation if found unique then no action to be taken.
Secondly want to make duplicate rows basis on grouping/concatenation of... (1 Reply)

__________________________________________________________________________________________________________________________________________________NAME
sum - Calculate a sum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2
package require sum ?1.1.0?
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
_________________________________________________________________DESCRIPTION
This package provides a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data. The
BSD sum algorithm is used by default but the SysV algorithm is also available.
COMMANDS
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
The command takes string data or a file name or a channel and returns a checksum value calculated using the sum(1) algorithm. The
result is formatted using the format(n) specifier provided or as an unsigned integer (%u) by default.
OPTIONS -sysv The SysV algorithm is fairly naive. The byte values are summed and any overflow is discarded. The lowest 16 bits are returned as the
checksum. Input with the same content but different ordering will give the same result.
-bsd This algorithm is similar to the SysV version but includes a bit rotation step which provides a dependency on the order of the data
values.
-filename name
Return a checksum for the file contents instead of for parameter data.
-channel chan
Return a checksum for the contents of the specified channel. The channel must be open for reading and should be configured for
binary translation. The channel will no be closed on completion.
-chunksize size
Set the block size used when reading data from either files or channels. This value defaults to 4096.
-format string
Return the checksum using an alternative format template.
EXAMPLES
% crc::sum "Hello, World!"
37287
% crc::sum -format 0x%X "Hello, World!"
0x91A7
% crc::sum -file sum.tcl
