问题描述

我需要并行运行的两个命令和从两者在相同的外壳得到的输出

I need to run two command in parallel and get the output from both in the same shell.

编辑：

我试图运行监控文件系统中的多个长期运行的命令和编制各种事情，我（的CoffeeScript，玉器，SASS）。

I am trying to run multiple long-running commands that watch the file system and compile various things for me(coffeescript, jade, sass).

推荐答案

你可能在bash看着等待命令。考虑一下这个脚本：

You're probably looking at wait command in bash. Consider this script:

#!/bin/bash

FAIL=0
echo "starting"

./script1 &
./script2 &

for job in `jobs -p`
do
   echo $job
   wait $job || let "FAIL+=1"
done

echo $FAIL

if [ "$FAIL" == "0" ];
then
    echo "All jobs completed!"
else
    echo "Jobs FAILED: ($FAIL)"
fi
