filenames

Before I go into detail I'll get right to the point: has anyone figured out a way to get Carrierwave to save files with their names as a timestamp or any arbitrary string that is unique to each file? By default Carrierwave saves each file and its alternate versions in its own directory (named after the model ID number). I'm not a fan of this because instead of one directory with 1,000, for the sake of using a large round number, files (in my case pictures) in it we get one directory with 1,000 subdirectories each with one or two files. Yuck. Now, when you override your Uploader's store_dir

When I save a file with an .htm or .html extension, which one is correct and what is different? Neither is wrong, it's a matter of preference. Traditionally, MS software uses htm by default, and *nix prefers html . As oded pointed out below, the .htm tradition was carried over from win 3.xx, where file extensions were limited to three characters. Mainly, the number of characters is different. ".htm" smells of Microsoft operating systems where the file system historically limited file name extensions (the part of the file name after the dot) to 3 characters. ".html" smells of Un*x operating

My bash script receives a filename (or relative path) as a string, but must then read from that file. I can only read from a filename if I declare it as a literal directly in the script (without quotes)...which is impossible for arguments since they are implicitly strings to begin with. Observe: a="~/test.txt" #Look for it if [[ -a $a ]] ; then echo "A Found it" else echo "A Error" fi #Try to use it while read line; do echo $line done < $a b='~/test.txt' #Look for it if [[ -a $b ]] ; then echo "B Found it" else echo "B Error" fi #Try to use it while read line; do echo $line done < $b c=~/test

I'm using very tricky fighting methods :) to make a string like Fi?le*/ Name safe for using as a file name like File_Name . I'm sure there is a cocoa way to convert it. And I'm sure the best place to ask is here :) Thank you! Unless you're explicitly running the shell or implicitly running the shell by using a function such as popen or system , there's no reason to escape anything but the pathname separator. You may also want to enforce that the filename does not begin with a full stop (which would cause Finder to hide the file) and probably should also enforce that it is not empty and is

Looking for a regex/replace function to take a user inputted string say, "John Smith's Cool Page" and return a filename/url safe string like "john_smith_s_cool_page.html", or something to that extent. Well, here's one that replaces anything that's not a letter or a number, and makes it all lower case, like your example. var s = "John Smith's Cool Page"; var filename = s.replace(/[^a-z0-9]/gi, '_').toLowerCase(); Explanation: The regular expression is /[^a-z0-9]/gi . Well, actually the gi at the end is just a set of options that are used when the expression is used. i means "ignore upper/lower
