Search All Directories for a Particular File Find Files in /Home Directory Regardless of Case Sensitive 2 Find Files by Name using find command.1 Examples of the file command in Linux.While the command-utility can search for files in multiple directories, by default the â find commandâ shows results of files in the current working directory. Users can search for files using the following criteria that find command supports â file pattern, name pattern, creation date, owner and permissions, folder, and modification date. Users can choose from several standards such as either search a matching filename or time range that matches when the file was accessed or modified. Therefore it is a utility for file hierarchy, where not only the user can leverage it to find data but also perform successive operations on it. More so, using the command, users can set specific search criteria and actions on files that match the search. It can search based on various criteria such as name, size, date modified, and others, and perform actions on the results such as printing, deleting, or executing other commands.įind Command is a command-line utility that locates files in one or more directory trees. does not work on linux and openbsd, only macOS."find" is a command-line utility in Unix-like operating systems that is used to search for files and directories in a specified location. ( basename takes only 1 path argument but xargs will send them all (actually 5000) without -n1. It gives the correct result and it's the fastest ¯\_(ツ)_/¯ $ alias f='time find /Applications -name "*.app" -type d -maxdepth 5' \į -print0 | xargs -0 -n1 basename | wc -l \į -print0 | xargs -0 -n1 -P 8 basename | wc -l \Ġm01.17s real 0m00.20s user 0m00.93s systemĠm01.16s real 0m00.20s user 0m00.92s systemĠm01.05s real 0m00.17s user 0m00.85s systemĠm00.93s real 0m00.17s user 0m00.85s systemĠm00.88s real 0m00.12s user 0m00.75s systemįunnily enough i cannot explain the last case of xargs without -n1. exec and -execdir are slow, xargs is king. $ time sh -c 'find /usr/lib -type f -print0 | xargs -0 -n 1 basename | cksum'Īs you can see, it really is substantially faster to avoid launching basename every time. $ time sh -c 'find /usr/lib -type f -print0 | xargs -0 basename -a | cksum' (For sake of a like-with-like comparison, the timings reported here are after an initial dummy run, so that they are both done after the file metadata has already been copied to I/O cache.) I have piped the output to cksum in both cases, just to demonstrate that the output is independent of the method used. Here is a timing comparison, between the xargs basename -a and xargs -n1 basename versions. Here I've included the -print0 and -0 (which should be used together), in order to cope with any whitespace inside the names of files and directories. If you use the -a option on basename, then it can accept multiple filenames in a single invocation, which means that you can then use xargs without the -n 1, to group the paths together into a far smaller number of invocations of basename, which should be more efficient.Įxample: find /dir1 -type f -print0 | xargs -0 basename -a | xargs -n 1), which may potentially be slow. As others have pointed out, you can combine find and basename, but by default the basename program will only operate on one path at a time, so the executable will have to be launched once for each path (using either find.
