CREATING COLUMNS FROM A SINGLE COLUMN FILE 1

[johngiggs]

I have a file that has a list of numbers in the first and only column. To shorten the output I would like to create a multiple column output.

I am attempting to use something like the following:

cat filename | nawk 'BEGIN{ FS="\n"; RS=""; OFS="\n"}{print $1, $2, $3, $4}'

Obviously that's not right because it's not working, but I can't seem to figure out what to do to get the output to look like the example below:

12345 234231243 12312 1234233
132134 894388 1241234 12341234

Any help would be greatly appreciated.

Thanks,

John

something like that to start with:

BEGIN {
if (cols == "&quot
cols=4;
}

{ printf("%-10s %s", $0, (FNR % cols) ? "" : "\n&quot }
vlad

| #include<disclaimer.h> |

Vlad,

That works great!! Thanks!! Is there another way to do this using something like the example I provided in my first post?

Thanks,

John

here's another way - a variation on my previous 'theme'. I don't think you can do anything similar yours though.

#--------------------
BEGIN {
if (cols == &quot;&quot
cols=4;
}

{ printf(&quot;%-10s &quot;, $0) }
!(FNR % cols) {print &quot;\n&quot;}

#----------------------
#----------------------
#----------------------
# here's script going the other way - multiple columns to
# the single column rows:
BEGIN {
OFS=&quot;\n&quot;
}
$1=$1 vlad
+----------------------------+
