Dear fellow Fedora users

I have a file with entries

\input{file1}
\input{file2}
...
\input{fileN}

How can I add extension
\input{file1.eps}
\input{file2.eps}
.
\input{file3.eps}

In case I need to add *jpg or *.png extension. I believe awk or sed would do the job. Thanks in advance

If all of the lines in the file need the same thing inserted into each line at the same position ( e.g. column 12) you could do this:

sed -i 's/./&.eps/12' filename

That will turn \input{fileN} into \input{fineN.eps}
