执行shell脚本中内置的命令字符串

Question

我正在尝试在 for 循环中构建命令字符串并执行它。 然而这并没有按计划进行。
事实上，运行注释中的最后两行似乎确实有效。 我该如何解决这个问题？如何以正确的方式构建命令字符串？

非常感谢任何帮助！

#!/bin/sh
JSONQUERYFILE="ReportingQueries.json"
JQCOMMAND="/C/gitBashCmd/jq-win64.exe"

for i in $($JQCOMMAND -c -r '.FilterQueries[].Id' $JSONQUERYFILE) 
    do
        #remove weird chars from $i...      
        forId=$(echo $i | tr -d '\r')
        jqFilterString=".FilterQueries[] | if .Id == \"$forId\" then \"YES\" else \"NOPE\" end"
        echo $jqFilterString 
        commandString="$JQCOMMAND -c -r '"$jqFilterString"' $JSONQUERYFILE"

        echo $commandString
        $($commandString)
#       echo /C/gitBashCmd/jq-win64.exe -c -r '.FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end' ReportingQueries.json
#       /C/gitBashCmd/jq-win64.exe -c -r '.FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end' ReportingQueries.json
done

注释中最后两行的输出似乎工作正常：（jq-win64 命令自行迭代）

.FilterQueries[] | if .Id == "274301" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r .FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end ReportingQueries.json
NOPE
YES
NOPE
NOPE
.FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r .FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end ReportingQueries.json
NOPE
YES
NOPE
NOPE
.FilterQueries[] | if .Id == "274004" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r .FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end ReportingQueries.json
NOPE
YES
NOPE
NOPE
.FilterQueries[] | if .Id == "274000" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r .FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end ReportingQueries.json
NOPE
YES
NOPE
NOPE

如果我们使用构建的命令字符串运行脚本，则输出如下：

.FilterQueries[] | if .Id == "274301" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r '.FilterQueries[] | if .Id == "274301" then "YES" else "NOPE" end' ReportingQueries.json
jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?) at <top-level>, line 1:
'.FilterQueries[]
jq: 1 compile error
.FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r '.FilterQueries[] | if .Id == "274005" then "YES" else "NOPE" end' ReportingQueries.json
jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?) at <top-level>, line 1:
'.FilterQueries[]
jq: 1 compile error
.FilterQueries[] | if .Id == "274004" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r '.FilterQueries[] | if .Id == "274004" then "YES" else "NOPE" end' ReportingQueries.json
jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?) at <top-level>, line 1:

jq: 1 compile error
.FilterQueries[] | if .Id == "274000" then "YES" else "NOPE" end
/C/gitBashCmd/jq-win64.exe -c -r '.FilterQueries[] | if .Id == "274000" then "YES" else "NOPE" end' ReportingQueries.json
jq: error: syntax error, unexpected INVALID_CHARACTER, expecting $end (Windows cmd shell quoting issues?) at <top-level>, line 1:

@dan @ikegami 非常感谢你的提示--arg。
这是更好的版本：

#!/bin/sh
JSONQUERYFILE="ReportingQueries.json"
JQCOMMAND="/C/gitBashCmd/jq-win64.exe"

for i in $($JQCOMMAND -c -r '.FilterQueries[].Id' $JSONQUERYFILE) 
    do  
        forId=$(echo $i | tr -d '\r')         #remove weird chars from $i...   
        echo $JQCOMMAND -c -r --arg idToSearch "$forId" '.FilterQueries[] | if .Id == $idToSearch then "YES" else "NOPE" end' $JSONQUERYFILE 
        $JQCOMMAND -c -r --arg idToSearch "$forId" '.FilterQueries[] | if .Id == $idToSearch then "YES" else "NOPE" end' $JSONQUERYFILE
done

它会产生以下输出：

/C/gitBashCmd/jq-win64.exe -c -r --arg idToSearch 274301 .FilterQueries[] | if .Id == $idToSearch then "YES" else "NOPE" end ReportingQueries.json
YES

/C/gitBashCmd/jq-win64.exe -c -r --arg idToSearch 274004 .FilterQueries[] | if .Id == $idToSearch then "YES" else "NOPE" end ReportingQueries.json
