外壳脚本错误：“循环”没有投掷预期的输出
我有JSON文件，可以从文件中提取颜色值。由于某种原因，它仅获取代码的一个块＆amp;其余的会引发错误。
摘要
#!/bin/bash
clear
echo "Add the figma json file path"
read path
figma_json="$(echo -e "${path}" | tr -d '[:space:]')"
echo "*****************************************"
color_values=$(cat $figma_json | jq -r '.color')
color_keys=$(cat $figma_json | jq -r '.color | keys' |sed 's,^ *,,; s, *$,,'| tr -s ' ' | tr ' ' '_')
echo $color_keys
for c_key in $color_keys
do
echo "key string: $c_key"
echo $color_values | jq ".$c_key.value"
echo "*********************************************"
done
输出
trimmed string: "gray1",
{
"description": "",
"type": "color",
"value": "#333333ff",
"extensions": {
"org.lukasoppermann.figmaDesignTokens": {
"styleId": "S:0b49d19e868ec919fac01ec377bb989174094d7e,",
"exportKey": "color"
}
}
}
null
*********************************************
trimmed string: "gray2" //Expected output
"#333333ff"
*********************************************
如果我们查看第二个输出，它将打印灰色的十六进制值，这是预期输出 请使用下面的链接获取JSON文件
I have json file which extract the color value from the file. For some reason, it only fetch only one block of code & for the rest it throws error.
snippet
#!/bin/bash
clear
echo "Add the figma json file path"
read path
figma_json="$(echo -e "${path}" | tr -d '[:space:]')"
echo "*****************************************"
color_values=$(cat $figma_json | jq -r '.color')
color_keys=$(cat $figma_json | jq -r '.color | keys' |sed 's,^ *,,; s, *$,,'| tr -s ' ' | tr ' ' '_')
echo $color_keys
for c_key in $color_keys
do
echo "key string: $c_key"
echo $color_values | jq ".$c_key.value"
echo "*********************************************"
done
Output
trimmed string: "gray1",
{
"description": "",
"type": "color",
"value": "#333333ff",
"extensions": {
"org.lukasoppermann.figmaDesignTokens": {
"styleId": "S:0b49d19e868ec919fac01ec377bb989174094d7e,",
"exportKey": "color"
}
}
}
null
*********************************************
trimmed string: "gray2" //Expected output
"#333333ff"
*********************************************
If we look at the second output it prints the hex value of gray2 which is the expected output

目前还不清楚您的目标是什么，但这是一种仅使用一次
jq调用即可从 JSON 文件读取数据的方法，而且很可能不需要使用sed或tr。您可以根据自己的喜好轻松调整选择和格式。演示
It's quite unclear what you are aiming at, but here's one way how you would read from a JSON file using just one call to
jq, and most probably without the need to employsedortr. The selection as well as the formatting can easily be adjusted to your liking.Demo
