我有一个文本文件，包含我需要摆脱的换行符。它有多个块，每个块之间有一个空行。它的格式如下：
A7233334 PALLETS 2 11.000 EACH

我需要用换行符拆开行，以便输出到这样的新文件：

有什么想法吗？
答案 0 :(得分：1)
这个awk one liner可以做到：
$ awk '{if ($0 ~ /&$/) {getline a; print $0,a} else {print }}' file
它得到以&结尾的行，并将它们与下一行连接起来。否则只需打印该行。
$ awk '{if ($0 ~ /&$/) {getline a; print $0,a} else {print }}' file

要删除多个空格或制作列，您可以使用| tr -s ' '和| column。
要删除前导空格，我们可以这样做：
awk '{if ($0 ~ /&$/) {getline a; gsub(/^[ \t]+|[ \t]+$/,"",a); print $0,a} else {print }}' file
基于https://stackoverflow.com/a/8766188/1983854。
测试：
$ awk '{if ($0 ~ /&$/) {getline a; gsub(/^[ \t]+|[ \t]+$/,"",a); print $0,a} else {print }}' file

答案 1 :(得分：0)
最后.......做对了.........：D
代码：
i=1;
sed -i '/^$/d' zlist3 ; ## this is the reason it took me quite some time :( , the damm thing messes up the code if there are blank lines in between in input file ....
cat zlist3 | nl | grep "\&$" | tr -s ' ' | cut -c1-4 >> ztest5.csv ;
limit=`cat zlist3 | wc -l`;
while [ $i -le $limit ]
do
grep $i ztest5.csv ;
if [ $? -ne 0 ]
then
sed -n "${i}p" zlist3 | tr -s ' ' >> zlist4 ;
else
tmp1=`sed -n "${i}p" zlist3`;
i=$(($i+1));
tmp2=`sed -n "${i}p" zlist3`;
echo "$tmp1 $tmp2" | tr -s ' ' >> zlist4 ;
fi
i=$(($i+1));
done
如您所见，代码基于序列号...........
输出：
Kaizen~
$ cat zlist4
