Is there a way to get find to output just the raw names? I'd pass -exec as argument to find instead pipe another command for the output avoiding the second command go over each output line, having said that, depending on the output it could improve the performance for the script. NOTE: find options are not positional -maxdepth affects tests specified before it as well as those specified after it.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I'm trying to run a find command for all JavaScript files, but how do I exclude a specific directory? Use the -prune switch.

For example, if you want to exclude the misc directory just add a -path. Here we exclude dir1 , dir2 and dir3 , since in find expressions it is an action that acts on the criteria -path dir1 -o -path dir2 -o -path dir3 if dir1 or dir2 or dir3 , ANDed with type -d.

Important Note: the paths you type after -path must exactly match what find would print without the exclusion. See note [1] if you'd like a better understanding. This is then grouped as a single expression with the escaped parenthesis, and prefixed with -not which will make find skip anything that was matched by that expression.

One might ask if adding -not will not make all other files hidden by -prune reappear, and the answer is no. The way -prune works is that anything that, once it is reached, the files below that directory are permanently ignored. This comes from an actual use case, where I needed to call yui-compressor on some files generated by wintersmith, but leave out other files that need to be sent as-is.

There is clearly some confusion here as to what the preferred syntax for skipping a directory should be. From the GNU find man page. Just specifying -not -path will still descend into the skipped directory, but -not -path will be false whenever find tests each file. Results are below. Both f10bit's syntax and Daniel C. Sobral's syntax took ms to run on average. GetFree's syntax , which doesn't use -prune , took ms.

So, yes this is a rather extreme example, but if you care about run time and are doing anything remotely intensive you should use -prune.

Note Daniel C. Sobral's syntax performed the better of the two -prune syntaxes; but, I strongly suspect this is the result of some caching as switching the order in which the two ran resulted in the opposite result, while the non-prune version was always slowest.

One option would be to exclude all results that contain the directory name with grep. For example:. The '-type d -name proc -prune' only look for directories named proc to exclude. The '-o' is an 'OR' operator. The tricky part is that find is very particular about the order of the arguments, so if you don't get them just right, your command may not work. The order of arguments is generally as such:.

The -path -prune approach also works with wildcards in the path. Here is a find statement that will find the directories for a git server serving multiple git repositiories leaving out the git internal directories:. But maybe you should use a regular expression , if there are many directories to exclude. There are plenty of good answers, it just took me some time to understand what each element of the command was for and the logic behind it.

Any directory or file that is not the. But they will be tested against the second expression. When find reaches the. So the -prune option will be applied to it. It tells the find command to not explore that directory. So any file or directory in. For example, But it will also print the print the full path of each directory one is skipping, as noted above. However, the following does not, This binds it to the right part of the -or clause due to boolean order of operations and associativity.

But the docs say there's a hidden -print if it or any of its cousins So why isn't the left part of the -or printing? Apparently and I didn't understand this from my first reading the man page , that is true if there there is no -print -or -exec ANYWHERE, in which case, -print is logically sprinkled around such that everything gets printed.

If even ONE print -style operation is expressed in any clause, all those hidden logical ones go away and you get only what you specify. Now frankly, I might have preferred it the other way around, but then a find with only descriptive operators would apparently do nothing, so I guess it makes sense as it is.

As mentioned above, this all works with -exec as well, so the following gives a full ls -la listing for each file with the desired extension, but not listing the first level of each hidden directory, For me and others on this thread , find syntax gets pretty baroque pretty quickly, so I always throw in parens to make SURE I know what binds to what, so I usually create a macro for type-ability and form all such statements as It's hard to go wrong by setting up the world into two parts this way.

You can find detailed instructions and examples in Linux find command exclude directories from searching. To effectively use the find I believe that it is imperative to have a good understanding of your file system directory structure. On my home computer I have multi-TB hard drives, with about half of that content backed up using rsnapshot i. Among the approached variously suggested in this thread How to exclude a directory in find. Let's say I want to find the system file libname-server The other solution offered in this thread SO also performs poorly:.

Here, I want to exclude a nested directory, e. Aside: Adding -print at the end of the command suppresses the printout of the excluded directory:. I was using find to provide a list of files for xgettext , and wanted to omit a specific directory and its contents.

I tried many permutations of -path combined with -prune but was unable to fully exclude the directory which I wanted gone. Although I was able to ignore the contents of the directory which I wanted ignored, find then returned the directory itself as one of the results, which caused xgettext to crash as a result doesn't accept directories; only files.

My solution was to simply use grep -v to skip the directory that I didn't want in the results:. Using grep was a quick and easy solution after some headache.

I have found this here. For those of you on older versions of UNIX who cannot use -path or -not. For what I needed it worked like this, finding landscape. The exec I tried command above, but none of those using "-prune" works for me. Eventually I tried this out with command below:.

This doesn't work for me either as it will include the ignored directory ". Theuni It probably didn't work for you because you didn't add a -print or any other action explicitly after -name. In that case, both "sides" of -o end up printing, whereas if you use -print , only that side prints. Sobral May 16 '13 at From manpage: Because -delete implies -depth, you cannot usefully use -prune and -delete together. So, how do I go about deleting with find if I want to exclude specific directories from the deletion?

To remove the entire directory itself from the results use: find. This question and the confusion in the answers is a manifest on how badly the find user interface matches onto what people need.

I'd add to this that you can exclude a directory at ANY level by changing the first. It still traverses all of the unwanted directory, though.

I'm adding my own answer.

Ways to Use ‘find’ Command to Search Directories More Efficiently

It goes without saying that every good Linux desktop environment offers the ability to search your file system for files and folders. But what about the command line? If you happen to frequently work in the command line or you administer GUI-less Linux servers, where do you turn when you need to locate a file? Fortunately, Linux has exactly what you need to locate the files in question, built right into the system.

Join , subscribers and get a daily digest of news, geek trivia, and our feature articles. However, there are several ways to use the command line to find files in Linux, no matter what desktop manager you use.

This tutorial will take you through the different ways of finding a directory in Linux. As you may already know, in Linux everything is a file including directories. And one of the common things a Linux user will do within the command line is searching for a file or a directory. There are several different means and utilities used for searching for files on the command line such as find , locate and which.

find command in Linux with examples

Search a folder hierarchy for filename s that meet a desired criteria: Name, Size, File Type - see examples. GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see Operators , until the outcome is known the left hand side is false for AND operations, true for OR , at which point find moves on to the next file name. The -H, -L and -P options control the treatment of symbolic links. That argument and any following arguments are taken to be the expression describing what is to be searched for.

To use the find command, at the Unix prompt, enter:. Leave the double quotes in. The find command will begin looking in the starting directory you specify and proceed to search through all accessible subdirectories. You may specify more than one starting directory for searching. By default, multiple options are joined by "and". You may specify "or" with the -o flag and the use of grouped parentheses.

Use the Unix find command to search for files

The Linux find command is very powerful. It can search the entire filesystem to find files and directories according to the search criteria you specify. Besides using the find command to locate files, you can also use it to execute other Linux commands grep , mv , rm , etc. If you just want to see some examples and skip the reading, here are a little more than thirty find command examples to get you started. Almost every command is followed by a short description to explain the command; others are described more fully at the URLs shown:.

Jun 18, - The find command will begin looking in the starting directory you specify and proceed to Specifies file type: f=plain text, d=directory man find. Some of the above information came from Essential System Administration.

In Unix-like and some other operating systems , find is a command-line utility that locates files based on some user -specified criteria and then applies some requested action on each matched object. It initiates a search from a desired starting location and then recursively traversing the nodes directories of a hierarchical structure typically a tree. The possible search criteria include a pattern to match against the filename or a time range to match against the modification time or access time of the file. By default, find returns a list of all files below the current working directory , although users can limit the search to any desired maximum number of levels under the starting directory.

How to Search for Files from the Linux Command Line

The find command in UNIX is a command line utility for walking a file hierarchy. It can be used to find files and directories and perform subsequent operations on them. It supports searching by file, folder, name, creation date, modification date, owner and permissions. It will search for sample.
