Thank you for the suggestion, and it would be a valid one in a different context. It's my fault for not being more specific about what I want to do. The situation is: ================= There are a set of commands implemented in Perl which make up a command line interface similar to the Bash prompt. Most of these commands display there output to STDOUT. I am attempting to wrap these commands with analogous subroutines in a Perl module, so that instead of printing to STDOUT, I capture a command's output, process it, and return meaningful values. Such a module is more reusable (and I have need of it). So you see I have to treat this command line interface as a blackbox, though it is possible, I am not 'permitted' to modify the strings that are spewed out when invoking a certain command. Finally even though I know about using backslashes and literals I don't know how to make use of them in the above code. Any other suggestions.	[reply]

The question I hear: I have a function that performs string interpolation. Without modifying the function, I want to prevent it from doing this interpolation. Either your question is unclear, or you might as well have asked I have a function that performs a loop. Without modifying the function, I want to prevent it from doing this loop. However, I'm pretty sure I'm understanding the problem incorrectly. Please provide more info. A minimal representative snippet would be ideal. The snippet you've already provided isn't representative of your problem.	[reply]

As mentioned, if you do not want the interpolation, escape the symbol... `print "\%dsadada ssadasd\n"; print "\@dsadada sdsadasd\n"; print "\$dsadada sdsadasd\n";` [download] OR, use single quotes... `print '%dsadada ssadasd' . "\n"; print '@dsadada sdsadasd' . "\n"; print '$dsadada sdsadasd' . "\n";` [download] Both of which will print: `%dsadada ssadasd @dsadada sdsadasd $dsadada sdsadasd` [download] What exactly do you want it to print instead?	[reply] [d/l] [select]
