问题
I am trying to search for file contents. The file is in a directory with sub folders.
The command
grep -l 'keyword'
is working and is finding all files which are under a folder. If I am searching in a folder with subfolders, I am not getting any results.
Is there any way to search file contents using a directory level search?
回答1:
You need to do something like this:
find . -type f -exec grep -l 'keyword' {} \;
You can also limit the find with the -name option and give it a shell regular expression, for example, '*.txt'.
Where '.' is the current folder you're in -- you can also give any directory path instead of '.' to search a given folder.
See: man find
回答2:
This usage grep each file under your current directory (including subdirectories).
find | xargs grep -l 'keyword'
Is that what you're looking for?
回答3:
find ./folder -type f -exec grep -l 'keyword' {} \;
Where ./folder is the folder you want to search
回答4:
You can use:
grep -rl 'keyword' *
