find a word 2

Hi All,

i need to find all the files in my system that contains a specific word.

for e.i : if a.txt contains "my_word" and c.txt contains "my_word"

so i want them to be in my_file.

the command below is not working properly..

find / -type f -exec fgrep -l "my_word" {} \;>/tmp/my_file

my_file-should contain a list of files that contains the word that i'm looking for.(a.txt,c.txt.......).

i posted this question,but i think i didnt explain myself.

hope someone can help.........

As I said before, in your other thread, try putting the {} and ; in single-quotes:

find / -type f -exec fgrep -l "my_word" '{}' ';' > /tmp/file_list

This works just fine for me.

Use grep -r, that goes through all files and directories recursively, so you don't need find.

find a word problem

Hi i tried to print the command below but the following error came:

find / -type f -exec fgrep -l "my_word" '{}' ';' > /tmp/file_list

the error :
fgrep: /proc/sys/net/ipv4/route/flush: Invalid argument

so,the system found a few files,but i know there are much more files.....

hope you can help.

Well, the files in /proc are generally not real files. Most of them are just an interface to statistics and information about your computer. So trying to run grep on some of them may cause problems.

Keep in mind that running this command on *everything* in your entire filesystem is not the greatest idea. Not only is it going to take forever, it doesn't make any sense to search /proc or /dev for matching words. It'd be better to run find several times, on say:

find /usr ...
find /home

And so on. And keep in mind what a poster in your previous thread said, that doing it this way starts a new process for fgrep every time a file is found (which is *many* times), making it even slower.

Try what llama_meme said - use grep -r

Use the man pages!
