![]() , so - is not necessary but apparently not all implementations do this. (like in this case) many implementations of find will print paths starting with. I used a double dash in case there's a file with name beginning with - that could be interpreted as an option.Therefore the two versions (with and with ) may differ in formatting their outputs. Heres the recursive search I performed in the previous example to do a grep search in the current folder: grep -r simple. With this option, grep will look into all the files in the current (or specified) directory and it will also look into all the files of all the subdirectories. The command is made up of different elements. On the other hand file that processes multiple arguments may columnize its output, so it looks "better". Grep provides a -r option for the recursive search. ![]() ![]() With file can get multiple operands ( find is still able to call file multiple times if there are too many files to build a single command). To use the find command, type: find /path/to/search -name 'filename'. type f -exec file - \ would also work, but then a separate file would be invoked for every file found. The find command will search through all of the files in the directory you specify. In the above approach such path will get to file in two or more lines and the tool will treat each line as a separate path to examine.Ī robust and portable way: find. The problem is with paths that contain newlines they are still valid in Unix (yet uncommon). Then file -f - expects one path per line. 4 PowerShell Find File Recursively using Recurse parameter. 2) Compile it to generate an executable file named FiF.exe. In PowerShell, using Get-ChildItem cmdlet to find files for search patterns or file by name. find prints each path with a trailing newline character, so it's usually one path (file) per line. Fast recursive find C program for Windows in command line 1) Save the source C file FiF.Thus, when the find command encounters a. -f option is not required by POSIX, some implementations of file may not support it. The find command takes a number of paths, and searches for files and directories in each path recursively.If a glob that doesn't match is expanded into an empty string by the shell, find will complain that it is missing an argument to -name.The other answer provides not the best way: find. The find command is recursive by default, meaning that it searches for results in the directories of directories contained in directories (and so on).If a glob that doesn't match is not expanded by the shell, find will (accidentally, mind you) exhibit correct behavior. ![]() Incidentally, if the glob had failed to match (no *.java files in the current directory), you would get one of two behaviors depending on how your shell is set up to handle globs that don't match (this is governed by the nullglob option in Bash, for example): Quoting prevents glob expansion and passes the command line to find as-is. This is a very simple solution using the tree command in the directory you want to search for. Which would obviously list the file in the current directory only (unless you happen to have some similarly-named files further down the tree). The find syntax is generally formatted as: find path options You can remove the path to search in the current directory (recursively), or the options (to display all file), but most of the time you will use both. This way, if you had, say, foo.java in the current directory, find's actual command line would be: find. Without the quotes, the shell interprets *.java as a glob pattern and expands it to any file names matching the glob before passing it to find. The problem is, you didn't quote your -name parameter.
