Print string with variables in AWK

Question

I am trying to parse android package list from phone. Sample data is as shown below.

  Package [com.google.android.as] (9faf0bc):
    userId=10320
    pkg=Package{299f845 com.google.android.as}

To parse data in AWK, I am using the command as under

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 = ""; } }'

Output of the above command is as under

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

The problem is the order of data output. The expected output should be in order between START and END as being printed. I am not able to get the structured data as desired. Please advise.

Answer 1

EDIT2

To output data for one package on one line, delimited by tabs, append | paste - - - - to the awk command, i.e. one dash for each of the 4 attributes selected. paste has a -d option to specify a delimiter.

Or you could use my original answer which did that - with attributes in specified order - if you passed -v isheader="" to awk.

EDIT

Second attempt, perhaps I misread:

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

or, as a one-liner:

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

Output:

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

You were very close but || operators were missing between regexes, and pkg was reset to an empty string in the second awk pattern.

(Original answer follows)

The output you posted is basically a conf file with key-value pairs but repeated for each 'Package' section.

The following awk script collects the values for attributes given in the att variable in an associative array (Val) and prints the array as tab-separated values (TSV) in one line per section, in the specified order.

OFS is awk's output field separator. Like the att and isheader variables OFS can be specified on the awk command line. It defaults to tab here but can be overridden with ofs="\\n" or ofs="|" for example.

Use with mawk or gawk as:

: ${ofs=$(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); }

Output from awk script (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

Output from shell script:
