我有一个带有222行和7752列的制表符分隔文本文件。以下是前4列和5行作为示例:
Individual Var1 Var2 Var3
personA A A A
personA T T T
personB G G G
personB C C C
我需要将代表每个人的两行合并为一行。也就是说,我需要将每个人的第二行中第一列的值移动到每个人的第一行的第二列,然后在所有行和列中重复此值。所以我最终每人只有一行(111行)并且两列(15,504)。因此,前7列和3行看起来像这样:
Individual Var1 Var1 Var2 Var2 Var3 Var3
personA A T A T A T
personB G C G C G C
如果有人能提出解决方案,也许会使用bash,我将非常感激?我还没有尝试解决方案,因为我对编码很陌生。

使用awk:
sed 1p file | awk '
{
n = split($0, line1)
getline
split($0, line2)
printf "%s", line1[1]
for (i=2; i<=n; i++)
printf "\t%s\t%s", line1[i], line2[i]
printf "\n"
}
' | column -t
Individual Var1 Var1 Var2 Var2 Var3 Var3
personA A T A T A T
personB G C G C G C
sed 1p file
是打印标题两次,因此awk可以看到标题两次,就像其他数据一样。

无论你使用什么语言,逻辑都是一样的。虽然bash对于这类事物来说并不是最快的,但它会正常工作。您只需要为每个人处理标题和 line1 和 line2 的读取顺序,并验证您是否拥有相同的人和该数字字段匹配,然后简单地将这些行交错成一行。
您可以执行以下操作:
\t
注意:打印personX
后的其他$ cat data.txt
Individual Var1 Var2 Var3
personA A A A
personA T T T
personB G G G
personB C C C
仅用于间距。您应该检查人的长度并根据需要进行调整。您可以根据需要调整间距以使用制表符或空格。
示例输入
$ bash cmblines.sh data.txt
Individual Var1 Var1 Var2 Var2 Var3 Var3
personA A T A T A T
personB G C G C G C

我希望这可以帮到你。我将所有内容都放入一个数组中,然后循环使用它。
readarray huge_array < <(tail -n +2 test.txt)
i=0;
while [ $i -lt ${#huge_array[@]} ]
do
name_of_person="$( echo ${huge_array[i]} | awk '{print $1}' )"
rows_person_one="$( echo ${huge_array[i]} | awk 'BEGIN { ORS=" " };{for (i=2; i<=NF; i++) print $i}')"
rows_person_one_second_line="$( echo ${huge_array[i+1]} | awk 'BEGIN { ORS=" " };{for (i=2; i<=NF; i++) print $i}')"
echo "$name_of_person $rows_person_one $rows_person_one_second_line"
((i+=2))
done
test.txt包含:
$ cat> test.txt
Individual Var1 Var2 Var3
personA A A A
personA T T T
personB G G G
personB C C C
输出是:
personA A A A T T T
personB G G G C C C
顺便说一下,您可以更改以下内容的打印行:
printf "$name_of_person \t $rows_person_one \t $rows_person_one_second_line \n"
如果你想要的是一个列表输出。
问候!
对于某些系统中没有“readarray”的情况,您可以使用:
while IFS= read -r line
do
huge_array+=("$line")
done < <(tail -n +2 test.txt)
i=0;
while [ $i -lt ${#huge_array[@]} ]
do
name_of_person="$( echo ${huge_array[i]} | awk '{print $1}' )"
rows_person_one="$( echo ${huge_array[i]} | awk 'BEGIN { ORS=" " };{for (i=2; i<=NF; i++) print $i}')"
rows_person_one_second_line="$( echo ${huge_array[i+1]} | awk 'BEGIN { ORS=" " };{for (i=2; i<=NF; i++) print $i}')"
printf "$name_of_person \t $rows_person_one \t $rows_person_one_second_line \n"
((i+=2))
done
