$ egrep -w -R 'word1|word2' ~/projects/ Task: Hide warning spam $ grep -w -R 'getMyData()' ~/projects/ Task: Search for two or more words In this example, search for word ‘getMyData()’ only in ~/projects/ dirctory: You can select only those lines containing matches that form whole words using the -w option. $ grep -h -R 'main()' ~/projects/*.c Task: Display only words You can pass the -h option to suppress inclusion of the file names in the output: The grep command shows output on a separate line, and it is preceded by the name of the file in which it was found in the case of multiple files.
To just display the filename use the cut command as follows: Sample outputs: filename.txt: redeem reward You can pass -H option to print the filename for each match: $ sudo grep -R "barfoo" /etc/ Task: Only display filenamesīy default, the grep command prints the matching lines. Hence, it is better to restrict the search to particular directory as per your needs: The above command may take a lot of time.
