I have an executable file in a directory, when I run that file (using ./file) I get an output file (.out), which are saved on the same directory of the executable file. I want this output to be saved in a subdirectory of the mentioned directory. What command/flag should I use?

>Solution :

Two possibilities:

• IF you redirect the output to file out yourself:

  cd directory || exit
  ./file >.out
  

  then you can do:

  cd directory || exit
  ./file >subdir/.out
  

• IF the file executable creates its own .out file:

  cd directory || exit
  ./file
  

  the .out file is created by the executable, and you cannot change it (ex. it is not a script), move the file yourself:

  cd directory || exit
  ./file && mv .out subdir
  

You could wrap this into a script, call it myfile:

  #!/bin/bash
  cd directory || exit
  ./file
  mv .out subdir/.out
