ECHO

  • echo prints the rest of the line to the screen (standard output).
  • This is useful for providing output or updates in a script.

  • Wildmasks (for filenames) and variables (values) are substituted in the argument before echo prints them.

  • Examples:
    $ echo Hello All!
      Hello All!
    $ echo sub*t1*
      sub1_t1.nii.gz sub2_t1.nii.gz
    $ echo j*k
      j*k
