我想在 AWS Batch 上编写终止作业的脚本,并且在将 UUID 分配给 bash 变量时遇到了问题。
我有一个名为“LastAndFinal_job_id_list.txt”的文本文件,其中包含如下两列:
cbac858b-3884-41c7-8bb7-97eeca8339ae LastAndFinal12

第二列中的“LastAndFinal*”是我提交给 AWS Batch 的作业名称列表,第一列中的 UUID 是 AWS Batch 返回给我的对应作业 ID。
我通过以下命令为作业名为“LastAndFinal22”的作业提取 UUID:
job_id=$(cat LastAndFinal_job_id_list.txt | grep -w LastAndFinal22 | cut -d ' ' -f 1)
现在的问题是当我 echo 时job_id
,我只得到空白输出。将 UUID 分配给变量“job_id”的任何想法?
