我有一个具有以下格式的文本文件:

line 450

10876 -022.6421047 -070.1866390 000882 23362.47 99 000000.00 10 202246.0

line 460

我需要做的是删除空白行,并在每个“第 XXX 行”行之间的每个数字块中连接 XXX。然后,删除以“line”开头的每一行。为了清楚起见,以下是所需输出文件的示例:

10876 -022.6421047 -070.1866390 000882 23362.47 99 000000.00 10 202246.0 450

I've got a textfile with the following format:

line 450

10876 -022.6421047 -070.1866390 000882 23362.47 99 000000.00 10 202246.0

What I need to do is delete the blanklines, and to every block of numbers between each "line XXX" line, concatenate the XXX. Then, delete every line starting with "line". For clarity, here is an example of the required output file:

10876 -022.6421047 -070.1866390 000882 23362.47 99 000000.00 10 202246.0 450

使用 awk (假设您的输入位于 file.txt 中并且结果位于 stdout 上):

awk '
/^line/ {number = $2}
/^[0-9]/ {print $0, number}
' file.txt

With awk (assuming your input is in file.txt and the result is on stdout):

awk '
/^line/ {number = $2}
/^[0-9]/ {print $0, number}
' file.txt

在 Perl 中,您可以执行以下操作:

perl -nle 'if(/^line/){($l = $_)=~s/\D//g;}elsif(/^\d/){print "$_ $l"}' file

In Perl you can do:

perl -nle 'if(/^line/){($l = $_)=~s/\D//g;}elsif(/^\d/){print "$_ $l"}' file

$ awk '$0 == "" {}
       $1 == "line" {line = $2}
       {print %0, line}' infile >outfile
$ awk '$0 == "" {}
       $1 == "line" {line = $2}
       {print %0, line}' infile >outfile

Sed 可能不是完成这项工作的最佳工具,但

sed '/^$/d;/line/{s/line //;h;d;};G;s|\n||' filename

请注意,除了一行数字之外,所有数字行都以空格结尾;该解决方案假设这是一个拼写错误,并且他们都应该这样做。如果没有人应该,那么使用这个:

sed '/^$/d;/line/{s/line //;h;d;};G;s|\n| |' filename

如果有些可能,有些可能不,那么请谨慎行事:

sed '/^$/d;/line/{s/line //;h;d;};G;s| *\n| |' filename

Sed probably isn't the best tool for this job, but

sed '/^$/d;/line/{s/line //;h;d;};G;s|\n||' filename

Note that all but one of your numeric lines ends with a space; this solution assumes that that was a typo and that they all should. If none should, then use this:

sed '/^$/d;/line/{s/line //;h;d;};G;s|\n| |' filename

and if some might and some might not, then play it safe:

sed '/^$/d;/line/{s/line //;h;d;};G;s| *\n| |' filename

awk '/line/{n=$2;next}NF{$0=$0 FS n;print $0}' file

ruby -ane 'n=$F[1] if /line/; print $_.chomp + " #{n}\n" if $F.size>0 && !/line/' file
awk '/line/{n=$2;next}NF{$0=$0 FS n;print $0}' file

ruby -ane 'n=$F[1] if /line/; print $_.chomp + " #{n}\n" if $F.size>0 && !/line/' file
