A problem with "grep" on a script

Hello every one,

I have two files : file1 and file2

- file1 contains one column and multiple lines.
- file2 contains multiple lines and multiple columns.

I want to do a script that compare the first column of file2 with the only column of file1 then took the lines that are the same and search for each line the whole line on file2 then write the result on a file that we can call RESULT.

Here is my script :

Code:
#!/bin/bash
more file2|awk '{print $1}'|while read line
do
     grep $line file1
done|while read ligne
do
     grep '^$ligne' file2
done

But I still do not have the result that I want.

Regards,

NAME
h5diff - Compares two HDF5 files and reports the differences. SYNOPSIS
h5diff file1 file2 [OPTIONS] [object1 [object2 ] ] DESCRIPTION
h5diff is a command line tool that compares two HDF5 files, file1 and file2, and reports the differences between them. Optionally, h5diff will compare two objects within these files. If only one object, object1, is specified, h5diff will compare object1 in file1 with object1 in file2. In two objects, object1 and object2, are specified, h5diff will compare object1 in file1 with object2 in file2. These objects must be HDF5 datasets. object1 and object2 must be expressed as absolute paths from the respective file's root group. Additional information, with several sample cases, can be found in the document H5diff Examples. OPTIONS
file1 file2 The HDF5 files to be compared. -h Print all differences. -r Print only the names of objects that differ; do not print the differences. These objects may be HDF5 datasets, groups, or named datatypes. -n count Print difference up to count differences, then stop. count must be a positive integer. -d delta Print only differences that are greater than the limit delta. delta must be a positive number. The comparison criterion is whether the absolute value of the difference of two corresponding values is greater than delta (e.g., |a-b| > delta, where a is a value in file1 and b is a value in file2). -p relative Print only differences that are greater than a relative error. relative must be a positive number. The comparison criterion is whether the absolute value of the difference 1 and the ratio of two corresponding values is greater than relative (e.g., |1-(b/a)| > relative where a is a value in file1 and b is a value in file2). object1 object2 Specific object(s) within the files to be compared. EXAMPLES
The following h5diff call compares the object /a/b in file1 with the object /a/c in file2: h5diff file1 file2 /a/b /a/c This h5diff call compares the object /a/b in file1 with the same object in file2: h5diff file1 file2 /a/b And this h5diff call compares all objects in both files: h5diff file1 file2 SEE ALSO
