[Casper] Flushing User Caches

[Thomas Larkin]

I just like using loops because I can change the rm -rf command to ls
-al for testing purposes and I don't have to rewrite a bunch of lines of
code, and I can use a large list of file paths.   That way nothing is
harmed.  Also, when working in home directories users can change things
around, so sometimes I use if and the touch command so if they rename
the file, then I create it, if the file exists then I delete it.

I have had users rename files for only god knows why in their home
directory.   Luckily none of my users by default have terminal access.

Your method works out fine as well, it is purely a preference thing.  I
sometimes also like to add a bit of chatting to my scripts so logs tell
me what they do, also a preference.

When you run a script via a Casper policy, $3 = the user's shortname. 
This
is why I structure my commands to target /Users/$3/
This may be a matter of preference, but I would skip the $file variable
and
the for loop in this case.  We're operating on known values.  To me,
at
least, it seems unnecessary to declare $file and then set up a for/if
structure when we can just operate on each item and save lines.

The script below accomplishes the goal with just a few lines and is set
up
to be run as part of a Casper policy triggered by login.

## Start script
#!/bin/bash

m -Rf /Users/$3/Library/Cookies/*
m -Rf /Users/$3/Library/Safari/*
rm -Rf /Users/$3/Library/Caches/Metadata/Safari/*
rm -f /Users/$3/Library/Preferences/com.apple.Safari.plist
rm -f /Users/$3/Library/Preferences/com.apple.Safari.RSS.plist

## End script

I save "for" loops for situations where you need to discover the item
to act
upon, i.e.
for i in $( dscl . -read /Groups/admin| grep GroupMembership:| awk
'{for (j=3;
j<=NF; j++) printf " %s", $j; printf "\n" }' )
to get a list of all members of the admin group, other than root.
