Searching for a word in several different files and directories at the same time


Hello friends,

I know how to search for filenames containing a certain word.

What I need is different - I need a command that searches for a word in a directory that contains many files - but note - the word is not in the title of the file, it is in the text.

Is there a way to find a command that scans the contents of all files in a directory searching for a specific word?

Thanks,

linux.girl

grep!
Code:
grep -Hw word *
prints filename:line
Code:
grep -hw word *
prints the lines only.
Code:
grep -lw word *
prints the filenames only.
Code:
man grep
for other options.

Yes, but I want to search several files at the same time - what you wrote me will search only in one specific file, or I got you wrong?

The shell replaces the * with all files in the current directory.
So grep will search the "word" in all of them.
You can restrict this to certain files.
For example *.txt means all files whose filenames end with .txt

One additionally interesting option might be -r ... to search directories recursively.

Maybe:
Code:
$ grep -r word /etc
will search every file in /etc, even subdirectories.

Unless the file you're searching is definitely binary, I'd suggest using the -I flag

Quote:
-I Process a binary file as if it did not contain matching data; this is
equivalent to the --binary-files=without-match option.
