Well, IBM publishes a new article about useful Unix command line habits as a follow-up to Michael Stutz’s article. I promise that after reading this article you will say something like “A-ha, I didn’t know you could do that!” Here is the part of that staff:
The !$ command returns the last argument used with a command. But what happens if you have a command that used arguments and you want to reuse just one of them? The !:1 operator returns the argument used in a command. The example in Listing 3 shows how you can use this operator in combination with the !$ operator. In the first command, a file is renamed to a more meaningful name, but to preserve use of the original file name, a symbolic link is created. The file kxp12.c is renamed in a more readable manner, then the link command is used to create a symbolic link back to the original file name, in case it’s still used elsewhere. The !$ operator returns the file_system_access.c argument, and the !:1 operator returns the kxp12.c argument, which is the first argument of the previous command.
$ mv kxp12.c file_system_access.c
$ ln –s !$ !:1
