While the OP's sample data consists exclusively of positive integers, if negative values and zeroes must be handled, neither solution is correct.
Corona's code will unconditionally set MAX to the next line's $3, if MAX is ever set to 0.
Yoda's code implicitly uses a max of 0 when NR==1 (a numeric 0 is the default value of an uninitialized variable). If that implicit 0, which is not present in the file, is greater than all values, B[2]==max will never succeed and no output is generated. max must be initialized from the first value of $3.

I have to send a file to mainframe and before sending it, I have to execute the quote command to set the record length.
Since the file is dynamic, I do not know what the maximum size of a line could be.
Currently, I use the following function to get the Max Column Count. Since I use "sed" it... (2 Replies)

The max value is 5800 from Ronaldo.
How can i do this in shell?
Thanks for all, folks. (11 Replies)
Hello all,
this should really be easy for you... I need AWK to print column maxima for each column of such input:
Input:
1 2 3 1
2 1 1 3
2 1 1 2
Output should be:
2 2 3 3
This does the sum, but i need max instead:
{ for(i=1; i<=NF; i++)
sum +=$i }
END {for(i=1; i in sum;... (3 Replies)
Hi Friends,
I have a file1 with 3400 records that are tab separated and I have a file2 with 6220 records. I want to merge both these files. I tried using join file1 and file2 after sorting. But, the records should be (3400*6220 = 21148000). Instead, I get only around 11133567. Is there anything... (13 Replies)

CMAP(5) File Formats Manual CMAP(5)NAME
cmap - format of .cmap files (color maps)
DESCRIPTION
Color-map files define the mapping between eight-bit color numbers and red, green and blue intensities used for those numbers. They are
read by Magic as part of system startup, and also by the :load and :save commands in color-map windows. Color-map file names usually have
the form x.y.z.cmapn, where x is a class of technology files, y is a class of displays, z is a class of monitors, and n is a version number
(currently 1). The version number will change in the future if the formap of color-map files ever changes. Normally, x and y correspond to
the corresponding parts of a display styles file. For example, the color map file mos.7bit.std.cmap1 is used today for most nMOS and CMOS
technology files using displays that support at least seven bits of color per pixel and standard-phosphor monitors. It corresponds to the
display styles file mos.7bit.dstyle5.
Color-map files are stored in ASCII form, with each line containing four decimal integers separated by white space. The first three inte-
gers are red, green, and blue intensities, and the fourth field is a color number. For current displays the intensities must be integers
between 0 and 255. The color numbers must increase from line to line, and the last line must have a color number of 255. The red, green,
and blue intensities on the first line are used for all colors from 0 up to and including the color number on that line. For other lines,
the intensities on that line are used for all colors starting one color above the color number on the previous line and continuing up and
through the color number on the current line. For example, consider the color map below:
255 0 0 2
0 0 255 3
255 255 255 256
This color map indicates that colors 0, 1, and 2 are to be red, color 3 is to be blue, and all other colors are to be white.
