Script to search for a string from a file

I am able to search for a string(with some pattern) from a file using grep command manually. But using some script, I want to take a line(each line is a string) from a file1 which has say some 100 unique lines and search each string in a different file2 and if present, output the complete line from file2

file1

abcd
efgh
ijkl
mnop

file2 

 somestring abcd somestring
 somestring somestring somestring
 somestring ijkl somestring
 somestring efgh somestring

You can use:

egrep -f file_one file_two

or

 grep -Ff file_one file_two

You can just use grep -Fwf:

grep -Fwf file1 file2
  • -F -> fixed string (no regex)
  • -W -> search for complete word
  • -f <pattern-file> -> take patterns from a file
