find

问题 I'm playing around with finding and replacing text. The only problem I'm having is finding a text string, that is not attached to an element with an ID. Otherwise, it would be easy. I'm trying something like this: $("*").each(function () { $(this).html(this.html().replace('Original Text','New Text')); }); Not working too well. Anyone run into this before? Also, if I have several words or phrases to find and replace, how does that affect the speed/processing power of the user's browser? Is it

问题 I was helped out today with a command, but it doesn't seem to be working. This is the command: find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 && rm {}\; The shell returns find: missing argument to `-exec' What I am basically trying to do is go through a directory recursively (if it has other directories) and run the ffmpeg command on the .rm file types and convert them to .mp3 file types. Once this is done, remove the .rm file that has just been converted. I

问题 When you do something like "test" in a where a is a list does python do a sequential search on the list or does it create a hash table representation to optimize the lookup? In the application I need this for I'll be doing a lot of lookups on the list so would it be best to do something like b = set(a) and then "test" in b ? Also note that the list of values I'll have won't have duplicate data and I don't actually care about the order it's in; I just need to be able to check for the existence

问题 I have not found a reason why Mac's find does not have the option -printf. Apple normally decides to take options out which are not orthogonal to the other commands? How can you reach the same result as the following command in Mac without coreutils? find . -printf "%i \n" // command in Ubuntu 回答1: It's not that Apple removes options, it's that OS X's UNIX underpinnings are mostly derived (circuitously) from FreeBSD, many parts of which can be traced back to the original UNIX... as opposed to
