我想将'版本'附加到前一行

例如：从：

ruby193-rubygem-therubyracer-doc.noarch
                                    0.11.0-0.5.beta5.el6
                                                      rhel-x86_64-server-6-ost-3

为：

ruby193-rubygem-therubyracer-doc.noarch 0.11.0-0.5.beta5.el6  rhel-x86_64-server-6-ost-3

并保留其他默认值。

Answer 1

$ gawk -v RS='\0' '{ gsub ("\n\\s+", " "); print }' inputfile | column -t

您需要任何评论吗？

Answer 2

awk 'NF<3 {ORS=""; i+=NF} NF==3||i==3 {ORS="\n";i=0}1' input | column -t

Answer 3

另一种变化：

awk '{$1=$1} /^ruby/{if(s)print s;s=$0;next} {s=s" "$0} END {print s}' file

{$1=$1}用于清理额外的空格。

Answer 4

使用xargs

xargs -n3 < file
