This command will search all files from the /tmp directory tree for a string: $ find /tmp -type f -exec grep 'search string' /dev/null '{}' \+ The /dev/null argument is used to show the name of the file before the text that is found.
grep is a command-line utility for searching plaintext datasets for lines that match a regular expression.Its name comes from the ed command g/re/p (global regular expression search and print), which has the same effect.
GNU grep, which supports a wide variety of POSIX syntaxes and extensions, uses BM for a first-pass prefiltering, and then uses an implicit DFA. Wu agrep, which implements approximate matching, combines the prefiltering into the DFA in BDM (backward DAWG matching). NR-grep's BNDM extends the BDM technique with Shift-Or bit-level parallelism.

Often a wrapper for the man -k command, the apropos command is used to search the "name" sections of all manual pages for the specified string or strings (called keywords). The output is a list of all manual pages containing the search term (case insensitive) in their name or description.
The version with the extra i runs the expression case-insensitive, and is even less efficient. Regex searches are likely to time out unless you further limit the search in some way, such as by including another parameter or a search term outside of the insource component of the search string.
In computer software, strings is a program in Unix, Plan 9, Inferno, and Unix-like operating systems that finds and prints the strings of printable characters in files. The files can be of regular text files or binary files such as executables. It can be used on object files and core dumps.
P denotes the string to be searched for, called the pattern. Its length is m. S[i] denotes the character at index i of string S, counting from 1. S[i..j] denotes the substring of string S starting at index i and ending at j, inclusive. A prefix of S is a substring S[1..i] for some i in range [1, l], where l is the length of S.
