help with command line

[loperam]

Hi there

I need some help with some instructions in command line

I must create a script to recover some specific lines of text in a file, there are two files, one of them contain all the original data and the other indicates what lines of text I need from the original file.

My question is: how can I get from my original file those specific lines of text based on my second file according to their line number?

Here are some data of my files:

Original file:
1 0.0,0.009146,0.113636,0.0,0.153846,0.0,0.157407,0. 02,TRUE
2 0.0,0.006098,0.0,0.007299,0.0,0.0,0.0,0.0,0.00885, TRUE
3 0.027778,0.045732,0.0,0.043796,0.0,0.0,0.027778, FALSE
4 0.009259,0.006098,0.0,0.00365,0.0,0.0,0.009259, TRUE
5 0.027778,0.02439,0.004545,0.018248,0.076923, FALSE
6 0.0,0.02439,0.0,0.029197,0.0,0.0,0.0,0.0, TRUE
...
835 0.166667,0.097561,0.0,0.051095,0.0,0.0,0.166667, FALSE

Second file:
1 2:TRUE 1:FALSE + 1
6 1:FALSE 2:TRUE + 1
20 1:FALSE 2:TRUE + 1
35 1:FALSE 2:TRUE + 0.978
56 1:FALSE 2:TRUE + 1
81 1:FALSE 2:TRUE + 0.999
115 1:FALSE 2:TRUE + 1

I need to get the lines 1,6,20,35,56,81,115... from my original file

Your help will be highly appreciated

Hey I got it!
Was very easy

cut -c1-6 result_file.txt > second_file.txt
while read myline
do
sed -n ${myline}p original_file.txt >>output.txt

done < second_file.txt

for i in `cat second_file | awk '{print $1}'`
do
grep ^$i orginal_file > output_file
done
