problems with "if"

[cayalee]

hi guys,
recently i've been building an automated backup script for our medical systems that run a version of linux on them.
i've had some success but cannot get "if" commands to work at all.
whereever they pop up, i get:

"if" syntax command

or something similar as an error message. commented out the script runs fine, but loses a nice touch of "detecting" which programs are installed.
can anyone give me any advice?

i've attatched the script as a .txt
thanks in advance!

#if [ ! -d "$BACKUPDIR" ]
#   then
#   echo "ERROR Couldn't find usb drive mounted at /mnt/#usbdisk. please mount to this directory"
#   exit 1
#fi

Itʼs simply a matter of a forgotten semicolon, because bourne shellʼs proper «if» construct syntax is:

if [ «CONDITION» ]; then
	«CODE»
fi

For more information about bashʼs syntax:

$> man bash
[…]
       if list; then list; [ elif list; then list; ] ... [ else list; ] fi
              The  if  list is executed.  If its exit status is zero, the then list is executed.  Otherwise, each elif list is executed in turn, and if its exit status is zero, the
              corresponding then list is executed and the command completes.  Otherwise, the else list is executed, if present.  The exit status is the exit status of the last com‐
              mand executed, or zero if no condition tested true.

I don't think it's a matter of missing semi-colons when the 'then' is on a separate line. The problem is further down the script, for example:

[ -d /usr/people/cranial ]
 then
echo "found Synergy Cranial. Preparing to back up"
cp /usr/people/cranial/cranialData/* /mnt/usbdisk/cranialData
echo "done"
 else
echo "synergy cranial not installed, skipping step"
endif

Which should be:

if [ -d /usr/people/cranial ]
 then
echo "found Synergy Cranial. Preparing to back up"
cp /usr/people/cranial/cranialData/* /mnt/usbdisk/cranialData
echo "done"
 else
echo "synergy cranial not installed, skipping step"
fi
