Suppose that I have a directory with name _file and includes two sub directory like _1 and _2 and on each one I have some text files. I want to search a word like foo in one of these text files. How I can do that? I want to know which text files in the whole directory contain that word?
If you don't want to install additional software, you can simply use
grep in the terminal. To recursively search through directories, you can use the
-r option (see
man grep for details). The syntax you are looking for is probably:
grep -r "[STRING TO SEARCH FOR]" "[DIRECTORY TO SEARCH]"
So, for instance if I want to search for the string "asdf" in all files in all subdirectories of "/tmp/testdir/" the command looks like this:
grep -r "asdf" "/tmp/testdir/"
The quotation marks are not strictly necessary, but if your string or directory path contains whitespaces, you otherwise would have to mask them using the \ character...
sudo apt-get install gnome-search-tool
Search in dash for 'search for files' and launch it.
See image below:
- Leave the 'name contains' section empty.
- Select your folder.
- Unfold the 'select more options' part and choose 'contains the text' and then press add.
- Type here the text you want to search for and click find at the bottom right corner.
