Ok. So we have a sequence of chars (a -, then some digits you may want to use for exclusion, then a .) once and only once in each line. So here it is:

#!/bin/bash

inputfile="/tmp/buddyfile"
cp...

#!/bin/bash

inputfile="/tmp/buddyfile"
cp "$1" $inputfile
(( $# < 3 )) || {
string="-${3}$"
for ((a=4;a<=$#;a++)); do
string+="\|-${!a}$"
done
...

No, 25% is calculated on the remaining lines (after you excluded two lines).
So 25% of 2 is 0.5, which rounds to zero.

Try: ./program Myfile 50 50 52
You'll get 1 line randomly chosen among 2...

In this file "-94" and alike are not at the end of lines, as they were before. So no lines were excluded. You got 50% of 5 lines, so 2 lines (2.5 rounds to 2).

If you want a good excluding...

Java is implemented in C++, so the answer to your question is, "yes, it's possible." The how depends on the particulars which you have not specified.

## Let's say that:
## the number of lines in your file is 200 (range=200);
## you want 30% of the lines in your file: percent=30.
## So we'll have that lim= 200 * 30 / 100 = 60.

If I'm right your problem is to randomly generate N integers in the range [1;M], where M is the number of lines in the file, and N is a rounded percentage of M.

Remember, a string is just an array of characters.
char *str=getenv("MYLIB");
