, 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. On the other hand file that processes multiple arguments may columnize its output, so it looks "better". With many options the find command might. 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). The find command recursively descends through the directory tree looking for files that match a logical expression. type f -exec file - \ would also work, but then a separate file would be invoked for every file found. The command uses find to search a directory tree and send the files through grep to search for a matching pattern in each file it locates. 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. It should search through a tree for a specified file. The problem is with paths that contain newlines they are still valid in Unix (yet uncommon). I am wondering how I would write a recursive program to locate a file in Java that is indicated by a starting path. For older Python versions, use os.walk to recursively walk a directory and fnmatch.filter to match against a simple expression: import fnmatch import os matches for root, dirnames, filenames in os.walk ('src'): for filename in fnmatch.filter (filenames, '.c'): matches.append (os.path. Then file -f - expects one path per line. find prints each path with a trailing newline character, so it's usually one path (file) per line.-f option is not required by POSIX, some implementations of file may not support it. Practical tutorial on how to search and find the files recursively in the Linux operating systems by using the name option, tree command, find command.The other answer provides not the best way: find. Finding files by name is probably the most common use of the find command.
