Is there any way of executing a mv command without typing the full path in the second argument?

Example:

mv my/file/that/has/a/really/long/path/foo.bar some_magic_operator_that_means_the_same_directory/foo.baz

Any reason you can't just cd to the directory and mv from there? –  zpletan Mar 27 '12 at 18:35
    
I frequently find myself executing these kinds of commands across multiple directories in my day to day work. I often need to execute several commands from a given parent directory. –  Finbarr Mar 27 '12 at 19:10
    
Somehow I found that using !! (double exclamation signs) in a terminal uses to run the last command executed. You can also add parameters/text to the last command but never tried to change/remove text from the last command. Try it and if you succeed I will drop this like an answer. Good luck! –  Geppettvs D'Constanzo Mar 27 '12 at 20:05

You can use bash's brace expansion. This:

mv my/file/that/has/a/really/long/path/foo.{bar,baz}

will expand into:

mv my/file/that/has/a/really/long/path/foo.bar my/file/that/has/a/really/long/path/foo.baz

and then mv is run with those two arguments. See http://wiki.bash-hackers.org/syntax/expansion/brace for more on brace expansion.

That's glorious. I didn't know you could do that. –  Finbarr Mar 27 '12 at 20:08

You might try:

pushd .
cd /really/long/directory/name/
mv whatever.1 whatever.2
popd

With a variable

  1. Save the directory in a variable : `DIR=./really/long/path/
  2. use move : mv "$DIR"foo.bar "$DIR"foo.bz

In one line : DIR=./really/long/path/; mv "$DIR"foo.bar "$DIR"foo.bz


Changing directory

  1. You could also cd to the directory you want to work in : cd ./really/long/path
  2. then change the file name : mv foo.bar foo.bz

In one line : cd ./really/long/path && mv foo.bar foo.bz

that second one looks familiar ;-) –  zpletan Mar 27 '12 at 18:44

Best use && in that last one-liner. Otherwise, if the cd fails, the mv will be run in the wrong directory, potentially overwriting a file. With cd ./really/long/path && mv foo.bar foo.baz, mv will only be run if cd succeeds in changing directory. –  geirha Mar 27 '12 at 19:02

You can you alias command to short the directory name:

alias src='/directory/name/of/source'
alias dst='/directory/name/of/destination'
mv src dst

-1 alias test='/var/log' ; cd test gives -bash: cd: test: No such file or directory. –  zpletan Mar 27 '12 at 18:50
