Question

To use the data from a publisher software, I have functions that I can call via the CLI (Linux Shell).

其中一人以以下格式向我汇报数据:

A space separates the first 5 columns, and one or two spaces separate the 5th and 6th columns. Sometimes columns 6 and 7 are empty.

目的是将一部分或全部数据归还给每个领域之间的限定文本档案。

为检索第1和第7栏,我使用了:

command | awk -F" "  { print $1,$7 }

但它规定:

2603290 TDCTAC01
2604594 TDCTAC01
2605631 B
2605657 B
2605663 B

Awk将填满空间的栏目视为多个相邻的分离器,而不是一个空栏,因此退回了以下非排他列的数据。

我如何获得X多个空间的顺序,这些空间被视为空栏,而有时有两个空间分立两栏?

Column N°6 can be composed of 1 to 6 numeric characters, so you cannot simply use a fixed width to delimit the column.

Answer 1

wrt Column N°6 may be composed of 1 to 6 numeric natures, so, You can only use a un width to delimiting the栏。 - ensuring You can。该栏的宽度固定在8个焦炭的宽度(或9个红利包括分离空间)下,使用该和三米铅/带白色空间(>>(,<6/code>)。

在这里,如何确定使用<代码>的千兆瓦的所有领域。 FIELDWIDTHS (with other awks You need a while (substr (substr) loop):

awk -v FIELDWIDTHS="7 9 5 2 5 9 9 2 16 3 8 2 3"  
{
    print "----"
    print $0
    for (i=1;i<=NF;i++) {
        gsub(/^ +| +$/,"",$i)
        print i, "<" $i ">"
    }
}
  file

例如:

$ cat file

。

$ awk -v FIELDWIDTHS="7 9 5 2 5 9 9 2 16 3 8 2 3"  { print "----"; print $0; for (i=1;i<=NF;i++) {gsub(/^s+|s+$/,"",$i); print i, "<" $i ">"} }  file
