How to capture the response from go run main.go
问题
我有一个名为main.go的Go脚本，我从shell脚本中调用它。main.go在成功时返回以下响应。我希望在调用main.go的同一个shell脚本中将返回的响应捕获到一个变量中。
> 运行go run main.go的响应

[1267.568ms] [rows:1] SELECT * FROM "pipeline1_2"."p_doc_pp_dates" WHERE filename LIKE '%11-004_M0_1_arm_1.d78d350eef91f1e72d801e064a088cf80d3c840a%' AND pagenumber = 38 ORDER BY begin desc LIMIT 1
第一个响应是当运行第一个文件时，没有内容可读取，第二个响应是当文件中有内容并且加载到表中时。
> 我尝试过类似以下的方法
go run main.go > return_resp
echo $return_resp
但是这并没有太大帮助。
英文:
I have go script main.go which I am calling it from shell script. main.go returns the response as below on success. I am looking to capture the return response in a variable from the same shell script I am calling main.go

First response is when ran first file where there is no content to read and second response in when there is something in the file and it loaded in the table
> I have tried something like
go run main.go > return_resp
echo $return_resp
however it was not much of help

得分: 5
你可以尝试以下代码：
return_resp=$(go run main.go)
echo $return_resp
或者
go run main.go > output.txt 2>&1
cat output.txt
关于 "2>&1" 的含义，你可以参考这个链接：What does "2>&1" mean?
英文:
You can try these
return_resp=$(go run main.go)
echo $return_resp
or
go run main.go > output.txt 2>&1
cat output.txt
