Question Combining elements of different commands in history

What is the correct format for a single command that would combine portions of 2 different lines in the command history? I'm using a C shell. Here's a simplified command history to clarify:

4 rm file1
5 ls -ld file2 file3 file4
6 cat file 5


With the above history, what would be the command to remove the files called file3 and file 5 using only history references and word identifiers? Here is what I was trying:

!4 5:2 6:1

...didn't work. I'm getting frustrated with having to repeatedly enter long pathnames, etc.

Thanks in advance for any help,
-Dbyte

why dont you create an alias?

Im not aware of most folks using C shell for normal admin work, although some do use it I am sure.

Most use ksh or sh or posix for HPUX.... I know that these have history functionality... works very well... Esc k works to scroll up thru commands and execute them and I also have autocomplete for long filenames, very handy.

Optimus_P - My question doesn't relate to any single command. I gave the sample only for clarification. I don't want to create an alias for each & every command that I might ever need in reference to the question. That would be way too much work (& require too much forsight) for a newbie like me! I was hoping that if I could get this question answered then this method would be simpler & less time consuming in the long run. I do love aliases though!

Kelum_Magnus - For better or worse C shell is where I'm at. My knowledge is minimal, so I'd rather figure out how to make my existing shell work for me than change it altogether. Again, this seems like a LOT of work to avoid this 1 circumstance. Generally I have been very pleased with the C shell. In fact, this is my 1st time being truly stuck trying to accomplish something in it.

So using the example I gave previously, can someone please show me the command I should be entering? Was I even close with my attempt? I know that this can be done, I just don't know how.

Thanks for your input guys. I do appreciate the insight of seasoned users.

I think that:
!4:0 !5:2 !6:1
will do it.
