Hi,
I have 20 files which have respective 50 lines with different values.
I would like to process each line of the 50 lines in these 20 files one at a time and do an average of 3rd field ($3) of these 20 files. This will be output to an output file.
Instead of using join to generate whole... (8 Replies)

Hi,
first, I have searched in the forum for this, but I could not find the right answer. (There were some similar threads, but I was not sure how to adapt the ideas.)

This code works perfect when using a machine with only one interface online. (Excluding the loopback of course) But when I have other interface up for vmware or a vpn the output gets mixed up. I know I had this working when I was just reading ip's from files so I know it is not a problem with... (8 Replies)
Hello there,
I found an elegant solution to computing average values from multiple text files
awk '{for (i=1;i<=NF;i++){if ($i!~"n/a"){a+=$i}else{b++}}}END{for (i=1;i<=FNR;i++){for (j=1;j<=NF;j++){printf (a/(3-b))((b>0)?"~"b" ":" ")};printf "\n"}}' file1 file2 file3

Hi all,
I have a list of numbers. I need an awk command to find out the numbers of elements (number of numbers, sort to speak), the average value the min and max value. Reading the list only once, with awk.

I need your help to discover missing elements for each box.
In theory each box should have 4 items: ITEM01, ITEM02, ITEM08, and ITEM10.
Some boxes either have a missing item (BOX02 ITEM08) or might have da duplicate item (BOX03 ITEM02) and missing another one (BOX03 ITEM01).

LEARN ABOUT SUNOS
sum
sum(1) User Commands sum(1)NAME
sum - print checksum and block count for a file
SYNOPSIS
sum [-r] [file...]
DESCRIPTION
The sum utility calculates and prints a 16-bit checksum for the named file and the number of 512-byte blocks in the file. It is typically
used to look for bad spots, or to validate a file communicated over some transmission line.
OPTIONS
The following options are supported:
-r Use an alternate (machine-dependent) algorithm in computing the checksum.
OPERANDS
The following operands are supported:
file A path name of a file. If no files are named, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of sum: LC_CTYPE, LC_MESSAGES, and
NLSPATH.
EXIT STATUS
The following exit values are returned.
0 Successful completion.
>0 An error occurred.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
|Availability |SUNWesu |
|CSI |enabled |
+-----------------------------+-----------------------------+
SEE ALSO cksum(1), sum(1B), wc(1), attributes(5), environ(5), largefile(5)DIAGNOSTICS
"Read error" is indistinguishable from end of file on most devices; check the block count.
NOTES
Portable applications should use cksum(1).
sum and usr/ucb/sum (see sum(1B)) return different checksums.
