30.5. My Favorite Is ^^
% cat myflie cat: myflie: No such file or directory % ^li^il cat myfile
Obviously, this doesn't save much typing for a short command, but it can sure be handy with a long one. I also use ^^ with :p (Section 30.11) to recall an earlier command so I can change it. For example:
% !m:p more gobbledygook.c % ^k^k2 more gobbledygook2.c
The point is sometimes not to save typing, but to save the effort of remembering, such as, I want to print the file I looked at earlier, but don't remember the exact name.
% lpr sources/aproggg.c lpr: sources/aproggg.c: no such file or directory % ^gg lpr sources/aprog.c
You could type ^gg^, but the second caret isn't required. With a single caret, you don't type a replacement string -- just the string to delete. -- JP]
