It is very common to try to find a file on our hard disk or within a directory and sub-directories. We can easily do that with the find command in Unix/Linux. Let’s say that I am looking for file names that contain the word report.
find . -iname "*report*"
Notice that the . refers to our current directory, we could have used the path explicitly like /home, the -iname will make find ignore the filename case, if you want to be case sensitive, you should use the -name and the * within the quotes refer to any character, so in essence, we are looking for file names that contain the substring report.
Regarding the Wildcard Characters which are useful for searching:
*Zero or more characters?Any one character[]Any character in the brackets
