macOS Need help with simple script...

[kellah]

I found a bunch of posts on the internet about this but I'm still running into problems. Here's my goal of my script: check to see if my external hard drive is mounted. (It's called "Files") and then use ditto to copy all the files over. I've got ditto to work but now that I'm trying to do an if-else statement it has problems.

Here's what I've got:

#!/bin/sh                                                                       

if (-e $d/$f) then
    ditto -V /Users/andrew/Misc /Volumes/Files/Backup
else
    echo "External drive not mounted!"
endif

When I try to run the script I get this error:

./backup: line 9: syntax error: unexpected end of file

What am I doing wrong?

I believe you want something like this:

#!/bin/sh

if [ -e $d/$f ]
then
    ditto -V "/Users/andrew/Misc /Volumes/Files/Backup"
else
    echo "External drive not mounted!"
fi

You will need the quotes around the path name if there is a space after "Misc". You won't if there isn't.

In the "if" statement, the spaces around the square brackets are very important. They don't like anything touching them. Very "separatist" of them.

The syntax you are using is from the C-shell (csh) or Korn shell (ksh), not the Bourne shell (sh) that you have specified on the first line.

If you specify "sh" on the 1st line, you need to use the square brackets, etc as the poster above has specified. Try changing line 1 to specify csh or ksh if you want to use your original syntax...
