find

grep

linux使用find命令和grep命令查找文件和文件内容

awk

curl

如果有特殊字符，导致解析失败

1. 用单引号引起来，这样会原封不动的使用，而不会尝试去解析

   curl -k -v -X POST "https://xxx.net/livy/batches" -u 'admin:xxx!QAZ' -H "Content-Type: application/json" -H "X-Requested-By: admin" -d '{"file":"/users/jingqicao/sparkSubmission/SAMStreaming/ver-01/bin/SAM-1.0-SNAPSHOT.jar", "driverMemory": "30G", "driverCores": 4, "executorCores": 14, "executorMemory": "98G", "numExecutors": 256, "name": "SAMStreaming-ver01-1020-02", "className":"com.microsoft.sam.SAMJobRunner", "args":["ver-01-1020-02","/users/jingqicao/sparkSubmission/SAMStreaming/ver-01/bin/SAMJob_4HD.conf"]}'
