Searching text with another file

rstengel · 11-13-2014, 06:54 AM

Is there a way to search a text file with a list of words from another file?

File 1 has list of words:
first
second
third
...

File 2 has a lot of text:
Search this file with all the words in File 1

I think this does exactly what you want

Code:

grep -f file1 file2

where file1 contains the terms you want to find in file2.

You may be interested (or not) in -i as well:

Code:

       -f FILE, --file=FILE
              Obtain  patterns  from  FILE,  one  per  line.   The  empty file
              contains zero patterns, and therefore matches nothing.   (-f  is
              specified by POSIX.)

       -i, --ignore-case
              Ignore  case  distinctions  in  both  the  PATTERN and the input
              files.  (-i is specified by POSIX.)

man grep for the various output options.

That works great and so simple. I didn't know it would be that easy.
Thanks
