Appending the line number and a seperator to each line of a file ? - Shell Programming and Scripting

pjcwhite · #1 (**permalink**) 03-20-2007

Hi, I am a newb as far as shell scripting and SED goes so bear with me on this one.

I want to basically append to each line in a file a delimiter character and the line's line number e.g

Change the file from :-

aaaaaa
bbbbbb
cccccc

to:-

aaaaaa;1
bbbbbb;2
cccccc;3

I have worked out how to append the ";" to the end of each line ( sed '1,$s/$/;/') but am stumped with the line number bit

.

This is on a Sun Solaris box btw.

Any help appreciated.

Thanks

Paul

aaaaaa;1
bbbbbb;2
cccccc;3
$ sed -n "p;=" file | sed "N;s/\n/;/"
aaaaaa;1
bbbbbb;2
cccccc;3
