Read 2 file line by line @ same time

HI All,

I am aware of reading one file line by line but now my requirement is to read 2 file line by line as below explained.
I have 2 files as below file 1 with spaces and file 2 same as file1 but without space and () brackets
now i have to read both file line by line and use first line of each file in some command
Code:
Desired output : abcdef ghi abcd ab ######################  abcdefghiabcdab
                                abcd 12345                 ######################  abcd12345
                                abdfd sdff ert (sdfre ere ert rrt)  ######################  abdfdsdffertsdfreereertrrt


File 1
Code:
abcdef ghi abcd ab
abcd12345
abdfd sdff ert (sdfre ere ert rrt)

File 2
Code:
abcdefghiabcdab
abcd12345
abdfdsdffertsdfreereertrrt

Please advise.

For a simple concatenation of the lines, consider paste
Code:
paste file1 file2

More flexible is the shell
Code:
while read L1 <&3 && read L2 <&4
do
  echo "$L1 #### $L2"
done 3< file1 4< file2
