我正在尝试从手机解析 android 包列表。样本数据如下所示。

要在 AWK 中解析数据，我使用如下命令

dumpsys package | awk '/^[ ]*Package \[.*\] (.*)/ { i = index($0, "[") + 1; pkg = substr($0, i, index($0, "]") - i); } /[ ]*versionCode=/ /[ ]*versionName=/  /[ ]*firstInstallTime=/ /[ ]*lastUpdateTime=/ { { print "START PackageName=" pkg $0 " END"; pkg = ""; } }'

上述命令的输出如下

versionCode=4371429 minSdk=30 targetSdk=30    versionName=R.3.sysimg.oem.325908743    firstInstallTime=2008-12-31 20:30:00START PackageName=com.google.android.as    lastUpdateTime=2008-12-31 20:30:00 END    versionCode=62209002 minSdk=21 targetSdk=29    versionName=2020.05.31.316831277.release    firstInstallTime=2008-12-31 20:30:00START PackageName=com.google.android.gm    lastUpdateTime=2008-12-31 20:30:00 END

问题是数据输出的顺序。预期的输出应该在 START 和 END 之间按顺序打印。我无法根据需要获取结构化数据。请指教。

要在一行上输出一个包的数据，由制表符分隔，请附加| paste - - - -到awk命令后，即为所选的 4 个属性中的每一个属性添加一个短划线。 paste 可以-d选择指定分隔符。

或者，如果您传递-v isheader=""给awk.

第二次尝试，也许我看错了：

dumpsys package | awk '
/^[ ]*Package \[/ { 
    pkg = substr($2,2,length($2)-2)
}
/^[ ]*(versionCode|versionName|firstInstallTime|lastUpdateTime)=/ { 
    print "START PackageName=" pkg $0 " END"
}
'

或者，作为单行：

dumpsys package | awk '/^[ ]*Package \[/ { pkg = substr($2,2,length($2)-2); } /^[ ]*(versionCode|versionName|firstInstallTime|lastUpdateTime)=/ { print "START PackageName=" pkg $0 " END"; }'

输出：

START PackageName=com.google.android.as    versionCode=4371429 minSdk=30 targetSdk=30 END
START PackageName=com.google.android.as    versionName=R.3.sysimg.oem.325908743 END
START PackageName=com.google.android.as    firstInstallTime=2008-12-31 20:30:00 END
START PackageName=com.google.android.as    lastUpdateTime=2008-12-31 20:30:00 END
START PackageName=com.google.android.gm    versionCode=62209002 minSdk=21 targetSdk=29 END
START PackageName=com.google.android.gm    versionName=2020.05.31.316831277.release END
START PackageName=com.google.android.gm    firstInstallTime=2008-12-31 20:30:00 END
START PackageName=com.google.android.gm    lastUpdateTime=2008-12-31 20:30:00 END

您非常接近，但||正则表达式之间缺少运算符，并且pkg在第二个 awk 模式中被重置为空字符串。

（原答案如下）

您发布的输出基本上是一个带有键值对的 conf 文件，但对每个“包”部分重复。

以下awk脚本将变量中给定的属性值收集到att关联数组 ( Val) 中，并按指定顺序在每节一行中将数​​组打印为制表符分隔值 (TSV)。

OFSisawk的输出字段分隔符。att和isheader 变量一样OFS可以在awk命令行中指定。它在此处默认为选项卡，但可以用ofs="\\n"或 ofs="|"例如覆盖。

与mawk或gawk作为：

: ${ofs=$(printf '\t')}
dumpsys-command |
awk -v OFS="${ofs}" -v isheader="" -f '/path/to/script' |
while IFS="${ofs}" read -r pkg vcode vname dt1st dtupd
do  printf '%s\n' '# -----' \
    "Package: ${pkg}" \
    "Version code: ${vcode}" \
    "Last update: ${dtupd}"
done

BEGIN {
    regexSectionStart = "^ *Package "
    keyvalsep = "="
    if ( !att )
        att="pkg  versionCode  versionName  firstInstallTime  lastUpdateTime"
    split(att, Att, "  ")
    for ( i in Att )
        Idx[Att[i]] = i
    if ( isheader )
        emitArr(Att)
}
$0 ~ regexSectionStart {
    emitArr(Val)
    for ( i in Val )
        delete Val[i]
    next
}
{
    key = substr($1, 1, -1+index($1,keyvalsep))
    if ( key in Idx )
        Val[Idx[key]] = substr($0, 1+index($0,keyvalsep))
}
## Print array in index order, skip if empty
function emitArr(V,  i,s) {
    for ( i in V ) {
        for ( i=1; i<=length(V); i++ )
            s = s (i==1 ? "" : OFS) V[i]
        print s
        return
    }
}
END{ emitArr(Val); }

awk脚本 ( )的输出isheader="x"：

pkg versionCode versionName firstInstallTime    lastUpdateTime
Package{299f845 com.google.android.as}  4371429 minSdk=30 targetSdk=30  R.3.sysimg.oem.325908743    2008-12-31 20:30:00 2008-12-31 20:30:00
Package{9e45ca8 com.google.android.gm}  62209002 minSdk=21 targetSdk=29 2020.05.31.316831277.release    2008-12-31 20:30:00 2008-12-31 20:30:00

shell脚本的输出：

Last update: 2008-12-31 20:30:00
