Oracle How to display only particular file location?
Hi Folks,

I tried to find a file from / directory and received big list of output like below.
Code:
$find / -name merge.txt
find: cannot read dir /var/sadm/pkg/SUNWcsmauth/save: Permission denied

find: cannot read dir /var/fm/fmd/rsrc: Permission denied
.....etc


Its really tough to find the file location from these many output Smilie.

I just wanted to find only the particular file with location like below.
Code:
$find . -name merge.txt
./merge.txt


Would appreciate if there is any better way to get this.

Regards,
Sri

Just redirect stderr to /dev/null to get rid of the error messages
Code:
find / -name merge.txt 2>/dev/null

The filename(s) found will still be printed to stdout.

Thanks hergp,

Great, it works well. could you tell me why we use /dev/null to redirect the stderr.

The file command writes the names of the files found to stdout and error messages, if any, to stderr, so the "useful output" is separate from diagnostic messages. This is standard unix behaviour.

Normally, both outputs go to your terminal. In this case we have redirected the diagnostic output to the dump and keep only the data output connected to the terminal.

Does that help?
