need help with a bash script

[Fabio Zyserman]

Hi all,

sorry if this is not the appropriate list to post my question,
but surely more than one guru here will be able to
guide me in my modest quest.

Here is my problem:


I have a lot of data files, which differ in their name by a number,
for example:
data-theta=0-np=1.2
data-theta=0-np=1.3
data-theta=0-np=1.4,
...and so on.

All files have the same structure (same number of columns and lines);
each single entry is a real number in free exp format, i.e. it looks
like this:
0.1224e01, but it is not important, I think

What I want to do is to create a new file, with one line from each of the
data files (say, line beginning with 0.01e00), adding to each line in
the new file the number appearing in the name of the corresponding data
file.
That is, the new file will contain one more column than the original
ones; the new
file would be
0.01e00 .... .... .... 1.2
0.01e00 .... .... .... 1.3
0.01e00 .... .... .... 1.4
.
.
Hope you can help!!!!

Many Thanks in advance!

rm -f newfile
for i in `ls data-*`
do
ls $i
printf `cat "$i" | grep -i "0.01e00"`  >> newfile
printf ".........." >> newfile
printf `basename $i | cut -d = -f 3` >> newfile
printf "\n" >> newfile
done


well.. you get the idea.

You probably want something along these lines:

#!/bin/bash

for file in `ls|grep data-theta`;
do
         number=$(echo $file|awk -F '=' '{print $3}');
         line=$(grep '0.01e00' $file);
         echo $line $number;
done;

Hope that helps.

Something like this should do it (if you were searching for 0.01e00):

grep 0.01e00 data-theta=0-np=* | sed 
's/^data-theta=0-np=\([^:]*\):\(.*\)/\2 \1/'
