With the command line we can  search for files containing specific word in Linux. There are several methods for searching some of them are described in this post.

1. Using Grep

grep -r  “word/string to be searched”  where to search

2. using Locate

locate {part_of_word}

but first update your locate database

#sudo updatedb

3. using find command

find . -name ‘*{part_of_word}*’ -print

Where “.”  is  directory where to search

you can use “*” as a wild-card

we can also use hybrid commands i.e mixture of above three to search more specific inside the string.
