A file that this command creates. If this
parameter is provided, then the command will only be run
if the specified file does not exist::
exec { \"tar xf /my/tar/file.tar\":
cwd => \"/var/tmp\",
creates => \"/var/tmp/myfile\",
path => [\"/usr/bin\",
\"/usr/sbin\"]
}
Is there a way to set the content of this file (/var/tmp/myfile) using some
additional parameter in the above syntax?

ahh, ok.
We are planning on using the "creates" parameter as an "run this
unless file is there" directive. Our scenario is that we need to run one
time scripts on machines. We figure we can use a file type to create a local
script to run, then use the exec to exec the script. At the end of the script we
will "touch /var/puppet/receipts/somefile". Might look something like
this. If there is a better way to push a one time script to nodes, please let me
know.
class run_one_time {
file { "/var/puppet/script/myscript001.sh":
content => "#!/bin/sh; do a bunch of stuff; touch
/var/puppet/receipts/myscript001;"
before => Exec[runOnce]
}
exec { runOnce:
command => "/var/puppet/script/myscript.sh",
creates => "/var/puppet/receipts/myscript001",
path => ["/usr/bin", "/usr/sbin"]
}
}

If you want to re-extract the file if the file doesn''t contain "testString" this should work. exec { "tar xf /my/tar/file.tar": cwd => "/var/tmp", creates => "/var/tmp/myfile", path => ["/usr/bin", "/usr/sbin"], unless => "grep testString myfile", } -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

If you don''t care about the contents of the file, just whether it''s there or not: unless => "/usr/bin/file MYFILE" or unless => "/usr/bin/stat MYFILE" or unless => "/bin/ls MYFILE" should all be pretty lightweight On Thu, Mar 4, 2010 at 12:06 PM, Patrick <kc7zzv@gmail.com> wrote:> > On Mar 4, 2010, at 7:29 AM, Allan Marcus wrote: > >> A file that this command creates.

Actually, if all "unless" looks at is the return code of the command I
would probably go with
unless => "test -e MYFILE"
If you use "test" you could also do more sophisticated things like
require the presence of a real file with "-f" and combine other tests
for
permissions or ownership.

The method you suggest is how we were first going to do a "one time script", but then we saw the "creates" parameter. What is the Creates parameter for then? Is it just redundant to [unless => "test -e MYFILE"] --- Thanks, Allan Marcus 505-667-5666 On Mar 4, 2010, at 2:36 PM, Steven VanDevender wrote:> Pete Emerson writes: >> If you don''t care about the contents of the file, just whether it''s >> there or not: >> >> unless => "/usr/bin/file MYFILE" >> >> or >> >> unless => "/usr/bin/stat MYFILE" >> >> or >> >> unless => "/bin/ls MYFILE" >> >> should all be pretty lightweight > > Actually, if all "unless" looks at is the return code of the command I > would probably go with > > unless => "test -e MYFILE" > > If you use "test" you could also do more sophisticated things like > require the presence of a real file with "-f" and combine other tests for > permissions or ownership. > >> On Thu, Mar 4, 2010 at 12:06 PM, Patrick <kc7zzv@gmail.com> wrote: >>> >>> On Mar 4, 2010, at 7:29 AM, Allan Marcus wrote: >>> >>>> A file that this command creates.
