text search


hi all

i want a search a text match, means a word it may be somewhere in some file.

for example assume a user name is test1

if i type: find / -name test1
it should search all files having this line (test1) match
i think the text (test1) should be somewhere in /etc/passwd

Thanks in Advance

You are not clear about what exctly you want. as far as I know there are basically two things available by default for searching e.g
1. if you are searching a file with a given name, then you can use the "find" command available in linux
2. if you are looking for a file that contains some specific words i.e you want to look inside the file then make use of "grep/rgrep/fgrep etc" which does the job.
If you are looking for someting else do let us know, may be you want to write some scripts/wrappers using the above mentioned commands. do let us know what exactly you want then we'll be in a better positon to help you out. thank you.

Smile find and grep

If you need to looking for a file with word "test1" you can use:
find / -name "*test1*"

Other wise if you need to look for a certain text on specify file you can use:
grep -i "test1" /etc/passwd

It will look for the word test1 on file /etc/passwd

Now if you prefer combine both, Ex. search on directory /home/test all file txt that have "test1" word in in, do:
$ grep test1 `find /home/test/*.txt -name "*.txt"`

I hope this will help you

Combine find and grep to find files that contain a specific word or phrase:

Code:
find /home/dis -type f|grep -l "Test data"
will produce a list of all files that contain the string Test data

However, it should be noted that, if this string is not on the same line, then the file would not be found (and of course you need permissions to read the file for the grep statement to work)

A small note - there's no need to use a pipe: find /home/dis -type f -exec grep -l "Test data" {} \; does the same thing.

You should be more careful on reading others' posts. Or just use "copy-paste" method. And, of course, read man grep about -l option ("ell", not "one").
Try this command:
Code:
find / -type f -exec grep -l "monkey" {} \;

That should be a lower case L character in the grep statement, not a number.

Also I would suggest not running find from / as you are likely to get a large amount of permission denied messages (unless you're running as root)

Assuming that you have the syntax right, is it possible that there is something about those files that makes them do strange thing with GREP? (Try it and see.)

Repeating earlier advice: You do not normally want to run find starting at the root directory (/). Use something like /home or /usr (or wherever the files are that you want to test).

I am not surprised that these files would cause problems.

The proc folder structure enables interaction with hardware and kernel functions and should not be treated as you would normal files.

Use the command grep -ri "keyword_you_are_looking_for" <locations_you_want_to_search_for_this_keyword>



This should do the trick.
