The “find” command allows you to search for files for which you know the approximate filenames. The simplest form of the command searches for files in the current directory and recursively through its subdirectories that match the supplied search criteria. You can search for files by name, owner, group, type, permissions, date, and other criteria.
To find files that match a specific pattern, use the “-name” argument. You can use filename metacharacters (such as “*”), but you should either put an escape character (“\”) in front of each of them or enclose them in quotes.
find . -name pro\*
if we want to find all the files that start with “pro” in the Documents directory, we would use the “cd Documents/” (without the quotes) command to change to the Documents directory, and then type the following command.
