Append to the right side ?

[shong9]

I have a series of text files of same height.

File A
--------
1
1
1
1
1

File B
--------
2
2
2
2
2

...
...



Is there easy way to append sideways ?

You could try bash's process substitution.

Or you could try something like below:

#! /bin/sh

while read f
do
	echo -n $f
	if read g
	then
		echo -n $g
	fi < two
	if read h
	then
		echo -n $h
	fi < three
	echo
done < one

Which reads from three files(one, two, three) one line at a time.

My bad that won't work but this will:

#! /bin/sh

exec 3<one
exec 4<two
exec 5<three

while read f
do
	echo -n $f
	if read g 
	then 
		echo -n $g
	fi <&4
	if read h
	then
		echo -n $h
	fi <&5
	echo

done <&3

exec 3<&-
exec 4<&-
exec 5<&-

exit 0

Hi.

The paste command is designed for this:

#!/usr/bin/env bash

# @(#) s1	Demonstrate paste, default parallel.

# Test run as external user.
# export PATH="/usr/local/bin:/usr/bin:/bin"
# Infrastructure details, environment, commands for forum posts. 
set +o nounset
LC_ALL=C ; LANG=C ; export LC_ALL LANG
echo ; echo "Environment: LC_ALL = $LC_ALL, LANG = $LANG"
echo "(Versions displayed with local utility \"version\")"
c=$( ps | grep $$ | awk '{print $NF}' )
version >/dev/null 2>&1 && s=$(_eat $0 $1) || s=""
[ "$c" = "$s" ] && p="$s" || p="$c"
version >/dev/null 2>&1 && version "=o" $p paste
set -o nounset

# Sample files, with head & tail as a last resort.
specimen data* \
|| { head -n 5 data* ; echo " --" ; tail -n 5 data* ; }

echo
echo " Results:"
paste -d "" data*

exit 0

producing:

% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0
