Searching an IP Address in one of the file from the whole system
Dear all,
I have to find out one IP Address which is configured in a file. This file I'm not aware & can be placed in any directory or sub-directory in the System OS is HPUX 11iv1. I could not find any option in "grep" with recursive search.

HI:
Don't use the '\;' terminator for find's '-exec'. Doing so means that you spawn *one* process for *every* entity that 'find' passes along.
Instead use the "+" terminator which signals the collection and bundling of very large number of arguments into a list that is passed to one or more spawned processes.
For small numbers of arguments, you probably won't notice the impact. In the case you are using, you will not only waste time but seriously degrade your system performance if you use '\;' instead of '+'.
Dennis meant to write:
# find / -exec grep -e "string1" {} +
...and most certainly meant to only examine files (and not directories too) by writing:

Another problem with ";" and grep is the fact that grep won't tell you the name of the file, since there is only one. Perhaps that's why Jai added -print to the end.

Hi (again) Vimal:

That's a good point. It's probably clearer (if for whatever reason one uses the ';' terminator to process one argument at a time) to do:
When 'grep' sees two file arguments it shows any matches with the file name for identification. Of course nothing will ever match the empty '/dev/null'.
