I see many examples and man pages on how to do operations like search-and-replace using sed. But, I want to match a given string or a regular pattern expression and display on the screen. How do I print lines with matching pattern using sed command only under Unix like operating systems?

I often type the wrong command as follows under Linux bash shell:
rsync -av dir1 user@server1.cyberciti.biz:/path/to/dir1
OR
cp -av file1*.txt file2*.txt /path/to/dest
I need to correct those command as follows:
rsync -av dir5 user@server1.cyberciti.biz:/path/to/dir1
cp -av delta1*.txt delta2*.txt /path/to/dest
How do I replace dir1 with dir5 or file with delta and repeat the last command under bash shell?
