Unix中两种文件的比较及显示差异

Question

我在Unix上有两个文件。我想比较一下这些文件-

用于显示两个文件中缺少的行的d_report_ref_date

• My

• 。用于显示两个文件中的实际差异的

• 。

• 能够跳过我不希望在报告中用于比较的列，例如，用于比较的唯一键是v_party_id

。

预期输出

Rows missing in file1: v_party_id="103811400"
Rows missing in file2: v_party_id="103811100", v_party_id="103811200"
Mismtach in row 1 for v_party_id="103811925": file1.n_pd_percent="0.16323687" file2.n_pd_percent="0.2045", file1.v_accounting_standard="IFRS" file2.v_accounting_standard="SQRT"
Mismtach in row 2 for v_party_id="36056030":  file1.v_accounting_standard="SQRT" file2.v_accounting_standard="IFRS"

代码：

BEGIN { FS="[= ]" }
NR==FNR {
    for (i=1; i<NF; i+=2) {
        file1[NR,i] = $(i+1)
    }
    next
}
{
    msg = sep = ""
    for (i=1; i<NF; i+=2) {
        if ( $(i+1) != file1[FNR,i] ) {
            msg = msg sep OFS ARGV[1] "." $i "=" file1[FNR,i] OFS FILENAME "." $i "=" $(i+1)
            sep = ","
        }
    }
    if ( msg != "" ) {
        print "Mismtach in row " FNR msg
    }
}

实际输出

 awk -f compare.awk file1 file2
Mismtach in row 1 file1.n_pd_percent="0.16323687" file2.n_pd_percent="0.2045", file1.v_accounting_standard="IFRS" file2.v_accounting_standard="SQRT"
Mismtach in row 2 file1.v_accounting_standard="SQRT" file2.v_accounting_standard="IFRS"
Mismtach in row 3 file1.v_accounting_standard="0.16323687" file2.v_accounting_standard="IFRS", file1.v_party_default_status_cd="IFRS" file2.v_party_default_status_cd="NOTDFLT", file1.v_party_id="NOTDFLT" file2.v_party_id="53565979", file1.v_src_system_id="53565979" file2.v_src_system_id="SMT"
Mismtach in row 4 file1.v_party_id="103811100" file2.v_party_id="103811400"

我可以在代码中做什么更改来以所需的格式显示输出？

Answer 1

这将实现我认为您想做的事情，您可能需要调整输出格式：

$ cat tst.awk
BEGIN { FS="[= ]" }
{
    match(" "$0,/ v_party_id="[^"]+"/)
    key = substr($0,RSTART,RLENGTH)
}
NR==FNR {
    file1[key] = $0
    next
}
{
    if ( key in file1 ) {
        nf = split(file1[key],tmp)
        for (i=1; i<nf; i+=2) {
            f1[key,tmp[i]] = tmp[i+1]
        }

        msg = sep = ""
        for (i=1; i<NF; i+=2) {
            if ( $(i+1) != f1[key,$i] ) {
                msg = msg sep OFS ARGV[1] "." $i "=" f1[key,$i] OFS FILENAME "." $i "=" $(i+1)
                sep = ","
            }
        }
        if ( msg != "" ) {
            print "Mismatch in row " FNR msg
        }
        delete file1[key]
    }
    else {
        file2[key] = $0
    }
}
END {
    for (key in file1) {
        print "In file1 only:", key, file1[key]
    }
    for (key in file2) {
        print "In file2 only:", key, file2[key]
    }
}
