问题说明
例如我有一个文件：
$ cat file
i am the first example.
i am the second line.
i do a question about a file.
和我需要：
example, line, file
我的意图有过awk，但问题是这样的词语在不同的空间
i intent with "awk" but the problem is that the words are in different space
正确答案
#1
尝试
$ awk 'NF>1{print $NF}' file
example.
line.
file.
要得到的结果在一行在你的榜样，请尝试：
To get the result in one line as in your example, try:
{
sub(/\./, ",", $NF)
str = str$NF
}
END { print str }
输出：
$ awk -f script.awk file
example, line, file,
纯bash的：
$ while read line; do [ -z "$line" ] && continue ;echo ${line##* }; done < file
example.
line.
file.
