what's the meaning for args?
- local hackbench_path
- [ -f /lkp/benchmarks/hackbench-git/hackbench/hackbench ] && hackbench_path=/lkp/benchmarks/hackbench-git/hackbench/hackbench
too long line? perhaps you like this: [ -f /lkp/benchmarks/hackbench-git/hackbench/hackbench ] && { hackbench_path=/lkp/benchmarks/hackbench-git/hackbench/hackbench } Thanks, Liushaofei
Good! I got it.
Thanks, Yale
