If you want to print files side by side, you have to print them at the same time.
Like you python script in your post#1 does.
In the shell the "read" command automatically chops the leading end trailing space.
Code:
while read L1 <&3 && read L2 <&4; do
echo "$L1$L2"
done 3< file1 4< file2
You see that it reads a line from file1 into variable L1 and simultaneously a line from file2 into variable L2. (Using two descriptors/streams that are opened when the loop starts.)
The echo command prints L1 and L2 side by side.
How to print file1 first then print file2 beside it after file1 has finished printed?
Need shell script to read two file at same time and print output in single file
Example I have two files 1) file1.txt 2) file2.txt
File1.txt contains
Aaa
Bbb
Ccc
Ddd
Eee
Fff
File2.txt contains
Zzz
Yyy

Hi all,

What is the easiest method to check if the copy file is completed? I'd like to get the solution in bash :) (8 Replies)

I have files named with different prefixes. From each I want to extract the first line containing a specific string, and then print that line along with the prefix.
I've tried to do this with a while loop, but instead of printing the prefix I print the first line of the file twice.

isympy - interactive shell for SymPy
SYNOPSIS
isympy [-c | --console]
isympy [ {-h | --help} | {-v | --version} ]
DESCRIPTION
isympy is a Python shell for SymPy. It is just a normal python shell (ipython shell if you have the ipython package installed) that exe-
cutes the following commands so that you don't have to:
>>> from __future__ import division
>>> from sympy import *
>>> x, y, z = symbols("xyz")
>>> k, m, n = symbols("kmn", integer=True)
So starting isympy is equivalent to starting python (or ipython) and executing the above commands by hand. It is intended for easy and
quick experimentation with SymPy. For more complicated programs, it is recommended to write a script and import things explicitly (using
the "from sympy import sin, log, Symbol, ..." idiom).
OPTIONS -c shell, --console=shell
Use the specified shell (python or ipython) as console backend instead of the default one (ipython if present or python otherwise).
Example: isympy -c python
FILES
${HOME}/.sympy-history
Saves the history of commands when using the python shell as backend.
BUGS
The upstreams BTS can be found at <http://code.google.com/p/sympy/issues/list> Please report all bugs that you find in there, this will
help improve the overall quality of SymPy.
