One way to do it, also assuming know how many instances of it you want to run, is in a loop, start the process in the background.
while (x < counter){
./process&
x++;

./runall.sh: line 7: syntax error: unexpected end of file
#!/bin/bash
while (x < 101)

Change this
To this and you should be good
The bash tutorial referenced in a previous post is a good read if you're going to be doing this a lot. There are more succinct ways of getting this done using bash's built-ins, but, I'm an old dog
Best wishes,

#!/bin/bash
while (x < 101)
{
./<filename> &
x++;
}To this and you should be good
#!/bin/bash
x=1
while [ $x -lt 101]
do
./filename &
let x=$x+1
