I'm using bash under Ubuntu.

Currently this works well for the current directory:

catdoc *.doc | grep "specificword" 

But I have lots of subdirectories with .doc files.

How can I search for, let's say, "specificword" recursively?

and maybe also return the name of the file that contains the word? – Tom Aug 31 '11 at 12:02

Use find for recursive searches:

find -name '*.doc' -exec catdoc {} + | grep "specificword"

This will also output the file name:

find -name '*.doc' | while read -r file; do
    catdoc "$file" | grep -H --label="$file" "specificword"

(Normally I would use find ... -print0 | while read -rd "" file, but there's maybe a .0001% chance that it would be necessary, so I stopped caring.)

Thanks grawity, the first suggestion works quit well. Is there a way to print the file name? it's only printing the phrase in which it has been found. – Tom Aug 31 '11 at 12:09
@user: Try the second suggestion, which, by the way, is titled "This will also output the file name". – grawity Aug 31 '11 at 12:10
Oh sweet :) thanks – Tom Aug 31 '11 at 12:11
can probably simplify a bit: find -name \*.doc -exec sh -c "catdoc '{}' | grep -q 'specificword' && echo {}" \; – glenn jackman Aug 31 '11 at 14:20

You might want to look at recoll which is a full-text search tool for Linux and Unix systems supporting many different document formats. However, it is index-based, i.e., it has to index the documents you want to search in before the actual search. (Thanks to pabouk for pointing this out).

There is a GUI and a command line, too.

See the documentation for further infos.

Maybe it is worth to note that Recoll provides indexed search. First it has to index the documents then it can search through the indexes. – pabouk Dec 17 '13 at 8:25

Grep should find binary matches with:

find /path/to/dir -name '*.doc' exec grep -l "specificword" {} \;
