I'd like to search the entire server by content. (text file)
When I try grep -rl "text here", it freezes.
How would you do it?
And how long does it usually take?

You need to specify a file when using the grep command. With the command you're using, you're searching in the standard input...
Try grep -r "test" directory.
find / -name "*.txt" -exec grep "text here" {} \; -print 2>/dev/null
Which can be explained in human speak as:
- find
- starting from /
- in all files named *.txt (quotes are to bypass shell interpretation)
- with the resulting hits, perform the following
- grep "test here"
- in the file {}
- end of exec (\;) escaped end of statement
- print the files that match
- redirect error messages in sink (since you might not be root, otherwise just sudo it).

1@Dennis. Depends on your mother tongue. In Japan and Korea,there are several character sets in which the backslash is also rendered as the Yen sign or the Wong sign (0x5c). Also, please have a look at u+20E5. In the past there have been several exploits in IIS in which you could explore the whole disk (where IIS had its root) of a PC just by mixing real slash and false (other equivalent unicode converted down in the ascii plan) slashes and at least one using reverse solidus overlay.

you forget to specify what sort of files you want to search,
make sure you log in as root
cd /
grep -rl "text here" * > /tmp/match.txt
this going to take a very long time, and you can collect the results later by checking /tmp/match.txt
The following command searches all the files ending with .txt in the the current working directory and all subdirectories:
find . -type f -name '*.txt' -exec grep -Hn "text here" {} \;
