filenames

Using ack (sometimes packaged as ack-grep) I know that I can find paths that contain a specific string by doing: ack -g somestring But what if I only want files which have "somestring" in their filenames ? You can use find utility. Something like this: find /path/to/look/in -name '*somestring*' -print On some systems, if you omit the path, current directory is used. On other systems you can't omit it, just use . for current directory instead. Also, read man find for many other options. I agree find is the way to go, but you could also easily do it with ack: ack -f | ack "string" Here, "ack -f"

I have a number of files in a folder, and I want to replace every space character in all file names with underscores. How can I achieve this? neesh This should do it: for file in *; do mv "$file" `echo $file | tr ' ' '_'` ; done I prefer to use the command 'rename', which takes Perl-style regexes: rename "s/ /_/g" * You can do a dry run with the -n flag: rename -n "s/ /_/g" * Use sh... for i in *' '*; do mv "$i" `echo $i | sed -e 's/ /_/g'`; done If you want to try this out before pulling the trigger just change mv to echo mv . What if you want to apply the replace task recursively ? How would

I keep getting myself in knots when I am manipulating paths and file names, because I don't have a common naming system that I use. I need to come up with a naming standard and stick to it, and I would like to be clear and consistent with others, so I am opening up to learn the canonical answers. Consider this toy problem: (Windows example, but hopefully answer should be platform independent) You have been given the full name of a folder: C:\users\OddThinking\Documents\My Source. You want to walk the folders underneath, and compile all the .src to .obj. At some point you are looking at the

I have developed an application that reads files from the folder chosen by the user. It displays how many lines of code are in each file. I want only Java files to be shown in the file-chooser (files having .java extension). Below is my code: public static void main(String[] args) throws FileNotFoundException { JFileChooser chooser = new JFileChooser(); chooser.setCurrentDirectory(new java.io.File("C:" + File.separator)); chooser.setDialogTitle("FILES ALONG WITH LINE NUMBERS"); chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); chooser.setAcceptAllFileFilterUsed(false); if (chooser

When you edit a question on stackoverflow.com, you will be redirected to a URL like this: https://stackoverflow.com/posts/1807421/edit But usually, it should be https://stackoverflow.com/posts/1807491/edit.php or https://stackoverflow.com/posts/edit.php?id=1807491 How was https://stackoverflow.com/posts/1807421/edit created? I know that Stackoverflow.com was not created by using PHP, but I am wondering how to achieve this in PHP? With apache and PHP, you might perform one of your examples using a mod_rewrite rule in your apache config as follows: RewriteEngine On RewriteRule ^/posts/(\d+)/edit
