Anyone have any tricks on how to do this?
There is ^old^new, but sometimes I have a short memory and forget what I just typed :\
I tried making a script, but found history doesn't work inside scripts.
| Code: |
last=$(!!$)
^${last}^${1}

have a look at the readline manual
typing C-P C-W tist will give you
or you can also type
or even C-A-0 C-Y toto which will do a
really, check the readline manual, there are a lot of valuable information:)

that isn't the problem. functions or aliases can get around that, the problem is your command can't work because of order of operations
the bash command substitution will not dereference a variable inside of the substitution string.
Or rather I can't get it too:
| Code: | ~ $ echo john
john
~ $ ^john^fred^
echo fred
fred
~ $ echo john
john
~ $ last="!!$"
last="john"
^${last}^fred^
bash: :s^${last}^fred^: substitution failed
|
I simply think it would be faster to do this:
try your command that you want to redo
then do Ctrl-p-w (just hit 'p' and 'w' in succession, no need to hold them down together.
