Question

I occasionally run a bash command line like this:

n=0; while [[ $n -lt 10 ]]; do some_command; n=$((n+1)); done

To run some_command a number of times in a row — 10 times in this case.

Often some_command is really a chain of commands or a pipeline.

Is there a more concise way to do this?

Answer 1

If your range has a variable, use seq, like this:

count=10
for i in $(seq $count); do
    command
done

Simply:

for run in {1..10}; do
  command
done

Or as a one-liner, for those that want to copy and paste easily:

for run in {1..10}; do command; done
