runtime.exec 실행시 지정된 파일을 찾을수 없으며 null 포인트 에러

Question

자바에서 런타임을 실행하는데 지정된 파일을 찾을수 없다고 뜨고 null포인트 에러도 나는데 무엇이 문제 인지 모르겠네요 ㅜ 도와주세요 호출하는 부분이구요if(mediaVO.getMediaId().startsWith("-")) mediaVO.setExposureCnt(executeCmd("grep '\"+mediaVO.getMediaId().trim()+"' $EXPOSURE_LOG/m."+batchDate+".log | wc -l")); else mediaVO.setExposureCnt(executeCmd("grep '"+mediaVO.getMediaId().trim()+"' $EXPOSURE_LOG/m."+batchDate+".log | wc -l")); --------------------------------------------------------public int executeCmd(String cmd) throws Exception{ Process process = null; Runtime runtime = Runtime.getRuntime(); StringBuffer successOutput = new StringBuffer(); StringBuffer errorOutput = new StringBuffer(); BufferedReader successBufferReader = null; BufferedReader errorBufferReader = null; String msg = null; boolean result = false; int cnt = 0; List cmdList = new ArrayList(); cmdList.add("/bin/sh"); cmdList.add("-c"); cmdList.add(cmd); String[] array = cmdList.toArray(new String[cmdList.size()]); try { logger.info("cmd : " + cmd); process = runtime.exec(array); } catch (IOException e) { logger.error(e.getMessage()); throw e; } return cnt;} 이렇게 실행 했을시 아래와 같은 로그가 나옵니다.2020-07-10 17:40:13,947 [ERROR] [MediaExposureServiceImpl.java:160] - Cannot run program "/bin/sh": CreateProcess error=2, 지정된 파일을 찾을 수 없습니다 2020-07-10 17:40:13,950 [DEBUG] [SqlSessionUtils.java:310] - Transaction synchronization deregistering SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@7d31082e] 2020-07-10 17:40:13,950 [DEBUG] [SqlSessionUtils.java:315] - Transaction synchronization closing SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@7d31082e] 2020-07-10 17:40:13,950 [DEBUG] [AbstractPlatformTransactionManager.java:855] - Initiating transaction rollback 2020-07-10 17:40:13,950 [DEBUG] [DataSourceTransactionManager.java:325] - Rolling back JDBC transaction on Connection [net.sf.log4jdbc.ConnectionSpy@6627cd19] 2020-07-10 17:40:13,951 [DEBUG] [Slf4jSpyLogDelegator.java:167] - 22.
