So I need to be able to inject a value into JSON using sed or awk (preferably on one line) and I cannot install any external libraries to help me.
所以我需要能够使用sed或awk（最好在一行）为JSON注入一个值，我无法安装任何外部库来帮助我。
An example of the json is something like {"version":"0.5363"}
json的一个例子就像{“version”：“0.5363”}
I'd need to be able to inject a new value for version.
我需要能够为版本注入新值。
Any help would be greatly appreciated.
任何帮助将不胜感激。

You could try the below sed command,
您可以尝试以下sed命令，
$ echo '{"version":"0.5363"}' | sed 's/\({"version":"\)[^"]*\("}\)/\1newvalue\2/g'
{"version":"newvalue"}
In the above sed command, replace the newvalue with value you want. Add inline edit option -i to save the changes made.
在上面的sed命令中，将newvalue替换为您想要的值。添加内联编辑选项-i以保存所做的更改。
sed -i 's/regex/replacement/g' file
