Bernhard- It would help if I understood better what you are trying to accomplish with the array... but a few things:
1) Look at section 11.1.2 at http://www.cfengine.org/manuals/cf3-reference.html#Introduction-to-functions for building array's from data 2) The error you're getting on this line "string[$(myarray)] string => execresult("/bin/egrep \"mypatter\" /localhost/somelocation/$(myarray) | cut ...", "noshell") may be for a few reasons. 1) missing close quote on variable name, or 2) $(myarray)" is not defined, and thus when you reference it you get the string "$(myarray)", which is as you say, illegal. Can you say, in words, what you want to do? Does something like readstringarray() do what you want? -Dan On Sep 23, 2010, at 6:33 AM, no-re...@cfengine.com wrote: > Forum: Cfengine Help > Subject: dynamic variable declaration > Author: bglomm > Link to topic: https://cfengine.com/forum/read.php?3,18441,18441#msg-18441 > > hi all, > > Could anybody give me a hint on how to construct variable names during > runtime (amount and names shall come from a "ls" command on a specific > directory) and fill each of this variables with a value extracted from the > corresponding file? > > > What I tried: > > In /localhost/somelocation/ > there are a bunch of files, let's say: test1, test2, othertest3 (arbitrary > unknown names). > each of this files contains a tagged line that I can get with egrep... and > extract with a simple cut... > Now I like to build an array of the form: > myarray string => "extracted-value-from-file-test1" > myarray string => "extracted-value-from-file-test2" > myarray string => "extracted-value-from-file-othertest3" > > in the "var:" section I can do a > > "allfiles" string => execresult("/bin/ls -x /localhost/somelocation/", > "noshell"); > "allfiles_array" slist => splitstring("$allfiles)", "\W", "20"); > ... so far all fine and works, but now I would need something like: > > "string[$(myarray)] string => execresult("/bin/egrep \"mypatter\" > /localhost/somelocation/$(myarray) | cut ...", "noshell") > > but that doesn't work (Variable identifier contains illegal character, i.e. > the $ ...) > > TIA > > Bernhard > > _______________________________________________ > Help-cfengine mailing list > Help-cfengine@cfengine.org > https://cfengine.org/mailman/listinfo/help-cfengine _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
