Is there any shortcut to reference the path of the first argument in a MV command?
And another way: brace expansion.
mv app/models/keywords_{builder,generator}.rbIn general,
before{FIRST,SECOND}afterexpands to
beforeFIRSTafter beforeSECONDafterSo it's also useful for other renames, e.g.
mv somefile{,.bak}expands to
mv somefile somefile.bakIt works in bash and zsh.
More examples:
You can use history expansion like this:
mv app/modules/keywords_builder.rb !#^:h/keywords_generator.rb!introduces history expansion.#refers to the command currently being typed^means the first argument:his a modifier to get the "head", i.e. the directory without the file part
It's supported in bash and zsh.
