How to add a character to the end of each line in a file in shell script
提问by user1483747
I need a script that add a particular character to the end of each line . I am using the command
sed 's/$/ foo/' r.txt
我需要一个脚本，在每一行的末尾添加一个特定的字符。我正在使用命令
sed 's/$/ foo/' r.txt
It adds foo to end of each line in the file r.txt and displays in my terminal . What do i need to do if i want to save this existing file with this new record appended after the end of each line .
它将 foo 添加到文件 r.txt 中每一行的末尾并显示在我的终端中。如果我想保存此现有文件并在每行末尾附加此新记录，我需要做什么。

To save to a new file:
要保存到新文件：
sed 's/$/ foo/' r.txt > newfile.txt
To edit in place
就地编辑
sed -i 's/$/ foo/' r.txt
