Isn't it easier just not to use %q in ls and run ls instead of ls -l|uq|awk '{print $10}' The rationale for q (quote) was that you still may want to get the name quoted to print a command that may be sent to rc, like in: echo rm `{q *.old} ^ permalink raw reply [flat|nested] 5+ messages in thread

I may have missed part of it, so if I'm restating anything or being terribly obvious, forgive me. Here's my 2 cents: I've become familiar with quoted arguments as in my CLIs the following is typical (where val is some value containing spaces). cli> set param 'val' I have a little function that breaks up the line into an argc & argv, similarly as I presume a shell would. Fairly simple, though I don't consider escape sequences or single quotes inside of an arg. I've been debating for some time whether to modify the input read routine such that when read in, cli> set param0 'set param1 \'set param2 \'val\'\'' the args will look like this: arg[0] == "set" arg[1] == "param0" arg[2] == "set param1 'set param2 \'val\''" ... essentially taking the outermost enclosed, escaped single quotes and unescaping them. It would obviously be fairly easy to do, but I've yet to run into a use for it. Also an avenue is unescaping all the quotes, as usual. I presume that option (b) in the replied to e-mail considers "fixing" programs such that if you output shell commands that require args containing spaces, we enclose the arg in quotes. Easy enough with %q. Since ' is a printable character, though, we run into inclusion problems ... right? What happens when we want to name files by ownership (ie: "Bob's file")? Does %q escape all ' inside the string it's enclosing? (online man page for print is still from 3E; no 4E for me just yet) If we're going to try changing these programs for this purpose, why not introduce a new format that outputs the string with spaces escaped? The shell should handle this just fine, right? ie (eg, z): print("%z", "This is a file name"); results in: This\ is\ a\ file\ name There would be caveats with this as well (suppose we want to print "this\ is\ a\ file\ name"), but is no more complex than the proposed ' solution. It just doesn't seem like we've arrived at a decent solution yet. Until we find one, I'm going to have to vote a (or perhaps d, if no one has tomatoes handy). Am I way off?
