How to convert a single column into several rows and columns?

I have a program which gives me the output as a single column with hundreds of rows like:


213
314
324
324
123

I want to be able to create a new file from this file which allows me to set the number of rows and columns in the new file, i.e. for this example, if I specify 3 rows and 2 columns, the output should look like

213 314
324 324
123


Is it possible to do this in Unix or using a pearl script?


Thank You,
Ashton.

This should give the desired output:

Code:
#!/bin/sh

rows=3
cols=2

awk -v r=$rows -v c=$cols '
NR<r*c{printf("%s",NR%c?$0" ":$0"\n");next}{print}
END{if(NR%c&&NR<r*c){print ""}}' file

If you get errors use nawk or /usr/xpg4/bin/awk on Solaris.

Regards

Hi.

See elsewhere on this site (the scripting forum) for a solution using paste.

You can also use pr with a few options:
Code:
#!/bin/bash -

# @(#) s2       Demonstrate column formatting.

echo
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1) pr
echo

FILE=${1-data1}

pr -a -t -s" " -2 $FILE

exit 0

producing:
Code:
$ ./s2

(Versions displayed with local utility "version")
SunOS 5.10
GNU bash 3.00.16
pr - no version provided for /usr/xpg4/bin/pr.

213 314
324 324
123

See man pages for details ... cheers, drl

drl,

If I understand the question, the OP should be able to specify the number of lines and columns.

Hi, Franklin52.

I allowed the data to determine the number of lines for a given number of columns -- does a general solution exist that allows both to be specified? I can't think of one off the top of my head. What should a solution do for data that exceeds rows X columns items of data?

If a specific number of lines needs to be specified with pr, paste, etc., say in the case of a limitation, then another tool could be used for that, either before or after formatting into columns... cheers, drl

The OP can give the answers if he clarifies why he needs to specify the columns and rows to convert his file.
