Edit Question
Title
Body
I want to append something at the end of a certain line(have some given character). For example, the text is: Line1: I just want to make clear of the problem Line2: Thanks to all who look into my problem Line3: How to solve the problem? Line4: Thanks to all. Then I want to add "Please help me" at the end of Line2: Thanks to all who look into my problem And "Line2" is the key word. (that is I have to append something by grep this line by key word). So the text after the script should be: Line1: I just want to make clear of the problem Line2: Thanks to all who look into my problem Please help me Line3: How to solve the problem? Line4: Thanks to all. I know sed can append something to certain line but, if I use sed '/Line2/a\Please help me' , it will insert a new line after the line. That is not what I want. I want it to append to the current line. Could anybody help me with this? Thanks a lot!
