linux - 如何删除文件中不需要的字符(使用 shell 脚本)

Question

我有一个看起来像这样的文件 (file.txt)

AYOnanl3knsgv2StRr44  CRITICAL","component  MMP-FileService  James.curren@wt.com  CODE_SMELL
AYOnanl3knsgv2StRr45  CRITICAL","component  MMP-FileService  James.curren@wt.com  CODE_SMELL
AYOnanl3knsgv2StRr46  CRITICAL","component  MMP-FileService  James.curren@wt.com  CODE_SMELL

AYODsI-Qknsgv2StRqai  MAJOR",               MMP-component    sam.curren@wt.com   CODE_SMELL

我必须删除第二列中不需要的字符 ","组件 和 ",

然后预期输出

AYOnanl3knsgv2StRr44  CRITICAL  MMP-FileService  James.curren@wt.com  CODE_SMELL
AYOnanl3knsgv2StRr45  CRITICAL  MMP-FileService  James.curren@wt.com  CODE_SMELL

这是我尝试过的

cat file.txt | tr -d '",' | sed 's/component//'

然后我得到的输出

我执行的 shell 命令也适用于其他列(在本例中它也适用于第 3 列)这就是我遇到的问题。有没有办法只为应用命令 第二列？

谁能帮我解决这个问题？提前致谢!

注意:我不允许使用 jq 或其他脚本语言，如 JavaScript、Python 等

Answer 1

它可以在单个 sub 中完成:

awk '{sub(/"[^[:blank:]]*$/, "", $2)} 1' file | column -t

这里:

• "[^[:blank:]]*$:匹配输入中以 " 开头的文本 ($2) 并替换它空字符串。
• column -t 仅用于表格输出，如果您不需要，可以将其删除。
