Rerunning the same command with a different parameter

Question

I know that I can run the following command

ls Some{File,Folder}

And it is equivalent to running this:

ls SomeFile SomeFolder

(I also use it a lot for things like mv place_{a,b})

However, I was wondering if there was a different shortcut where I could do something like this:

run-command --a --whole --lot --of --flags parameter a; \
     run-command --a --whole --lot --of --flags parameter b

And I only had to type run-command --a --whole --lot --of --flags parameter {a,b} or something similar.

Answer 1

Assuming that you are using the GNU bash or something similar:

Perhaps a for loop?

for x in a b
do
    run-command --a --whole --lot --of --flags parameter $x
done

which can also be written in one line as for x in a b; do ; run-command --a --whole --lot --of --flags parameter $x ; done

Answer 2

You can also use a function, which doesn't limit you to having your changing argument at the end:

runcom() { run-command --a --whole --lot --of --flags parameter "$1" ; }

runcom a
runcom b

Answer 3

There is alias command in bash:

$ alias shotcommand='run-command --a --whole --lot --of --flags parameter'

The usage is: $ shotcommand a
