\f0\b\fs28 \cf0 Munki SelfService (On Demand) Script Tips
\f1\b0\fs24 \
\

\fs28 This is just a reminder of what Greg has written on the munki dev forum.\
\

\f0\b 1) Byline (also called \'93the Shebang\'94)
\f1\b0 \
Start the script with a byline on its own line:\
\pard\pardeftab720\partightenfactor0

\f2 \cf0 \expnd0\expndtw0\kerning0
#!/bin/bash
\f3 \
or \

\f2 #!/bin/sh
\f3 \
\

\f4\b 2) References
\f3\b0 \
When the script is run from inside the plist you have to be quite literal.\
\
Tools need to be referenced in full\

\f2 /usr/bin/osascript
\f3  instead of 
\f2 osascript\
/bin/rm
\f3  instead of 
\f2 rm
\f3 \
\
File references can\'92t start with 
\f2 ~/ 
\f3 for the Home directory
\f2 \

\f3 You need the full path:
\f2  /Users/username/Library/Preferences/..
\f3 \
You can tease out the actual active user account name with:\
\

\f2 #Get User Name\
userName=$(stat -f "%Su" /dev/console)\

\f3 \
And then pop it into the reference as a variable like this:\

\f2 /Users/$userName/Library/Preferences/..
\f3 \
\

\f4\b 3) Characters
\f3\b0 \
If the script is coming from a plist then you want to prevent the XML parser from misinterpreting certain characters. \
\'93>\'94, \'93<\'93 and \'93&\'94 are all used in XML so you need to spec them in HTML\
&gt; for >\
&lt; for <\
&amp; for &\
\
\'97\
