Question

我有大的制表符分隔的双列文本文件，如下所示：

...
"001R_FRG3G"    "81941549; 47060116; 49237298"
"002L_FRG3G"    "49237299; 47060117; 81941548"
"002R_IIV3" "106073503; 123808694; 109287880"
...

如您所见，第二列不包含原子值。这就是我想要＆＃34;正常化＆＃34;这个文件有类似的东西：

...
"001R_FRG3G"    "81941549"
"001R_FRG3G"    "47060116"
"001R_FRG3G"    "49237298"
"002L_FRG3G"    "49237299"
"002L_FRG3G"    "47060117"
"002L_FRG3G"    "81941548"
"002R_IIV3" "106073503"
"002R_IIV3" "123808694"
"002R_IIV3" "109287880"
...

任何人都知道如何有效地做到这一点？

Answer 1

awk '{for (i=2; i<=NF; i++) {gsub(/[";]/, "", $i); printf "%s%s\"%s\"", $1, OFS, $i; printf "%s", "\n"}}' inputfile

对于$1之后的每个字段，引用引号和分号，然后打印$1，后跟引号括起的字段内容。对输入文件中的每一行执行此操作。

Answer 2

的Perl：

perl -lne '
s/[";]//g;
($a, @b) = split;
print qq("$a" "$_") for @b;
' FILE

Answer 3

这可能适合你（GNU awk）：

awk '{while(/;/) $0=gensub(/^((.*[ \t]").*);[ \t]*/,"\\1\"\n\\2",1)};1' file
"001R_FRG3G"    "81941549"
"001R_FRG3G"    "47060116"
"001R_FRG3G"    "49237298"
"002L_FRG3G"    "49237299"
"002L_FRG3G"    "47060117"
"002L_FRG3G"    "81941548"
"002R_IIV3" "106073503"
"002R_IIV3" "123808694"
"002R_IIV3" "109287880"

或者，它并不是awk，但它优雅地解决了这个问题。

sed -i ':a;s/\(\(.*\s"\).*\);\s*/\1"\n\2/;ta' file
"001R_FRG3G"    "81941549"
"001R_FRG3G"    "47060116"
"001R_FRG3G"    "49237298"
"002L_FRG3G"    "49237299"
"002L_FRG3G"    "47060117"
"002L_FRG3G"    "81941548"
"002R_IIV3" "106073503"
"002R_IIV3" "123808694"
"002R_IIV3" "109287880"
