find command

I use 'find' to search some string,

my command is

Code:

find  /root -name "*" -size -50k  | xargs grep -H -n -w "8088"

but I got something like

grep: /root/Azureus: No such file or directory

how to avoid this ?

Thanks.

Presumably, you mean "find /", to start searching from / (the root of the filesystem tree), rather than /root, which is a directory in / (and the root user's home directory).

No, I know that directory is NOT existed in anywhere. I just want to skip this error message when finding & grep.

Thanks.

But /root does exist

Are you using the root account as a normal account?

I'll bet that Azereus is a directory. Read through the info manual for find. There are other options you can use:

find /root -type f -size -50k | xargs grep -H -n -w "8088"

The -name "*" doesn't do anything useful.

regardless of whether you intended to search "/" or "/root", do the first half of the command first--to be sure that you know what it is doing.

If you just want to suppress error messages, then add this to the end of the command: 2>/dev/null

Only /root/azerues (low-case) existed. If it is existed, why it outputs "no such file or directory" ?

Thanks.

This is what I am looking for. Thanks.

BTW, do we have any way to skip binary file, not search binary files ?

Thanks.

Thanks.

somehow, use the "file" command (returns the type of a file)
