[英]How to remove new line using linux command
I have a file that contains data as follows: 我有一个包含数据的文件,如下所示:
text1, text2, text3,
text4
text5, text6, text7,
text8
I need to bring the text4, text8 to the previous line that ends with a comma. 我需要将text4,text8带到以逗号结尾的上一行。 How can I achieve this please ?
请问我该如何实现?
EDIT: Please, note that I have thousands of line. 编辑:请注意,我有数千行。 I need to automate the process.
我需要使过程自动化。
Try the following perl
command: 尝试以下
perl
命令:
$ perl -p -e 's/,\n/, /g' file
text1, text2, text3, text4
text5, text6, text7, text8
> perl -pe 'if(/,\n/){$_=~s/\n//g}' temp
text1, text2, text3,text4
text5, text6, text7,text8
do it inplace : 就地执行:
perl -pi -e 'if(/,\n/){$_=~s/\n//g}' temp
Perl is probably the easiest tool: Perl可能是最简单的工具:
perl -wpe 'chomp if /,$/' file
This says: Print all the lines of "file", but leave out the newline if the line ends on a comma. 这说:打印“文件”的所有行,但是如果该行以逗号结尾,则省略换行符。
