In Windows, I would have done a search for finding a word inside a folder. Similarly, I want to know if a specific word occurs inside a directory containing many sub-directories and files. My searches for grep syntax shows I must specify the filename, i.e.
grep string filename.
Now, I do not know the filename, so what do I do?
A friend suggested to do
grep -nr string, but I don’t know what this means and I got no results with it (there is no response until I issue a Ctrl + C).
grep -nr 'yourString*' .
The dot at the end searches the current directory. Meaning for each parameter:
-n Show relative line number in the file 'yourString*' String for search, followed by a wildcard character -r Recursively search subdirectories listed . Directory for search (current directory)
grep -nr 'MobileAppSer*' . (Would find
'MobileAppASer*.*' is another way to do the same thing.)
To check more parameters use man grep command.
