Scope

For brevity, the word file in this manual means a regular file, a directory, a symbolic link, or any other kind of node that has a directory entry. A directory entry is also called a file name. A file name may contain some, all, or none of the directories in a path that leads to the file. These are all examples of what this manual calls "file names":

parser.c
README
./budget/may-94.sc
fred/.cshrc
/usr/local/include/termcap.h

A directory tree is a directory and the files it contains, all of its subdirectories and the files they contain, etc. It can also be a single non-directory file.

These programs enable you to find the files in one or more directory trees that:

• have names that contain certain text or match a certain pattern;
• are links to certain files;
• were last used during a certain period of time;
• are within a certain size range;
• are of a certain type (regular file, directory, symbolic link, etc.);
• are owned by a certain user or group;
• have certain access permissions;
• contain text that matches a certain pattern;
• are within a certain depth in the directory tree;
• or some combination of the above.

Once you have found the files you're looking for (or files that are potentially the ones you're looking for), you can do more to them than simply list their names. You can get any combination of the files' attributes, or process the files in many ways, either individually or in groups of various sizes. Actions that you might want to perform on the files you have found include, but are not limited to:

• view or edit
• store in an archive
• remove or rename
• change access permissions
• classify into groups

This manual describes how to perform each of those tasks, and more.
