A bourne shell (sh) script is a list of lines in a file that are
executed in the bourne shell (a forerunner of bash); simplest is just
commands that could be run at the prompt.
-
The first line in a sh script MUST be
#!/bin/sh
-
Things to remember:
- always make sure it has executable status
chmod a+x filename
- script runs in the current directory (pwd)
- may not inherit the same environment - esp. if used by others
- Example:
#!/bin/sh
bet im1 im1_brain -m
mv im1_brain_mask.nii.gz mask1.nii.gz
- A script can be stopped at any point by using
return: e.g. return 0
