Re: [Puppet Users] Unrecognised escape sequences
Hi, it aint our issue: we dont actually need to include escape chars into strings, our need is - for example - to escape delimitators ( , ' ) inside command lines; in fact ,we're used to compose very complex tiny scripts with subshells for the 'command' field into 'exec' resources, etc.. Please help, greets, Matteo 2011/2/9 Felix Frank felix.fr...@alumni.tu-berlin.de On 02/08/2011 04:09 PM, mt321_0987 wrote: unfortunately, we keep getting this warns into the system log by puppet masters: [...] Unrecognised escape sequence '\CHAR' in file PATH [...] but then everything works fine; also, without using escapes, catalogs dont work on agents.

Please ,let us know ASAP and tell us if this problem will prevent remote execution in future versions, thanks If you have strings that include backslashes, you should really escape those backslashes, i.e.: onlyif = grep two\ words /tmp/file, # WRONG! onlyif = grep two\\ words /tmp/file, # right In some cases, you can use single quotes instead onlyif = 'grep two\ words /tmp/file', # right too but you loose flexibility.

My comment was not targeted at escaping specific characters. Whatever you escape, if you want puppet to transfer a backslash to the client, and the string containing that backslash is double-quoted in your manifest, you should escape that backslash and avoid any ambiguity.

Re: [Puppet Users] Unrecognised escape sequences
Hi, the problem we are facing is not the transfer of backslash escape+non-specific character; we need puppet not to log the warns into the syslog when catalogs are prepared and commands such as command = /bin/echo \\$(echo bin)\, are processed for compiling Our syslogs are full of [...] Unrecognised escape sequence '\non-specific character' [...] Please help, thanks Greets, Matteo 2011/2/9 Felix Frank felix.fr...@alumni.tu-berlin.de On 02/09/2011 12:13 PM, M C wrote: Hi, it aint our issue: we dont actually need to include escape chars into strings, our need is - for example - to escape delimitators ( , ' ) inside command lines; in fact ,we're used to compose very complex tiny scripts with subshells for the 'command' field into 'exec' resources, etc..
