Grrr. I have the exec{} below in my puppet module. How do I escape the
\ characters? I''ve tried every possible combination I can think of.
I''ve used one, I''ve used two, and I''ve used THREE \.
exec {
''oracle-extract-part'':
command => "/usr/bin/printf
\"n\np\n2\n2091\n+16384M\nw\n\" | /sbin/fdisk /dev/xvdj",
unless => "/bin/cat /proc/partitions | /bin/grep
${orcl_ephm_device}2";
}
With three \, it ends up looking like this in the log:
Nov 21 01:27:45 dev-c3-app-15 puppet-agent[3091]:
(/Stage[main]/Oracle::Server11g/Exec[oracle-swap-part]/returns) change
from notrun to 0 failed: /usr/bin/printf
\"n\#012p\#0121\#0121\#012+32768M\#012t\#01282\#012w\#012\" |
/sbin/fdisk /dev/xvdj returned 1 instead of one of [0] at
/etc/puppet/devmp/modules/oracle/manifests/server11g.pp:136
Now... that''s obviously not right. How do I escape \ symbols?
Doug.

I''d deploy a wee script that does what you are trying to handle in the command string, and just call that instead. On 21 Nov 2011, at 06:30, Douglas Garstang wrote:> Grrr.

Say you wanted to use printf to print a newline. You would run this: (1) printf \n But, the backslash has special meaning in bash (or most shells). If you type that in bash, you have to escape it, one of these ways: (2) printf \\n (3) printf ''\n'' Puppet runs commands through a shell. So, you will have to apply escaping appropriate for whatever shell is in use. But, the command is also in a string. Backslashes have special meaning in puppet strings. So, we know the command we want to give to bash is: (4) printf \\n To put that in a puppet string we need to escape the \: (5) "printf \\\\n" If you don''t like all the backslashes, you could give single quotes to bash: (6) "printf ''\\n''" This is example 3, quoted with puppet''s rules. You could also use single quotes in Puppet, but Puppet''s single-quote strings still find special meaning in \, so it doesn''t really get you anything, and if you are using single quotes for bash it''s actually worse. You''d need this: (7) ''printf \''\\n\'''' Given (7), puppet will give (8) to bash: (8) printf ''\n'' and bash will give to exec(): (9) printf \n Make sense? -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

How about using the alternate single quotes in ruby

Right - forgot that :). Maybe support for an alternate quoting operator should be added.

I placed the printf string in a separate variabe, then I can double quote the
variable and it will take care of escaping correctly.
$fdisk_cmd = "c\nu\nn\np\n1\n\n\nw\n"
exec { "fdisk /dev/${name}":
command => "printf \"$fdisk_cmd\" | fdisk
/dev/${name}",
unless => "cat /proc/partitions | grep ${name}1",
path => ''/sbin:/bin:/usr/bin'',
}
