![]() You can also specify an extension to search for the string. In general, grep searches for a word, phrase, or pattern. You can read more about grep by typing the man command. This command can be case-sensitive or case-insensitive. It searches all files containing the string you want. For example, in the command below, grep will find “.log” in a directory. When the command finds a matching string, the output will show the name of the file and the line number. This search can cover all files in a directory or groups of files. Using the grep command, we can find multiple strings and patterns. In a Linux terminal, can we grep multiple strings? The answer is yes. What is the Difference Between Grep And Egrep?.You can use grep to search for multiple files with multiple patterns. This option will print all lines with the specified pattern. The -R option will search all subfolders of the file. When searching for multiple words, you can also use the -R option to make your search case-insensitive. In this case, the pattern is a text file, which is searched with grep. Grep can search multiple words or strings in a file by using a regular expression. When you use grep with a file extension, your search will take place across all files with that extension. This flag makes it possible to search for multiple patterns without case-sensitivity. In other words, if you want to find multiple words or strings in one line, you can use the -c flag to make your search case-insensitive. The grep command allows you to search for a string based on its case sensitivity. When used in this way, you can use grep to find the most commonly used words and phrases in a file. When used in this way, grep will return the same number of words or strings before and after matching. ![]() It can also match exact phrases, whole words, or a single line. The command grep can be used in UNIX to search for multiple words or strings in a file.
