Why does my shell script not find anything (find . -name script.sh | grep watermelon)

I have a script that I'm running from the home directory to search for all files called "script.sh" that contai开发者_开发百科n the string "watermelon". It's not finding anything but I can clearly see these scripts in the subdirectories. Could someone please suggest a change to the command I'm using:

find . -name script.sh | grep watermelon

You need to use xargs:

find . -name script.sh | xargs grep watermelon

xargs will modify the behavior to search within the files, rather than just search within the names of the files.

find returns the filename it finds by default. If you want it to search within the files then you need to pipe it to xargs or use the -exec and -print predicates:

find . -name script.sh -exec grep -q watermelon {} \; -print

---

use -type f to indicate file

find . -type f -name "script.sh" -exec grep "watermelon" "{}" +;

or if you have bash 4

shopt -s globstar
grep -Rl "watermelon" **/script.sh
