How do I remove “permission denied” printout statements from the find program?
When I run this command in Linux (SuSE):
find / -name ant
I get many error messages of the form:
find: `/etc/cups/ssl': Permission denied
Does find
take an argument to skip showing these errors and only try files that I have permission to access?
you can filter out messages to stderr
. I prefer to redirect them to stdout
like this.
find / -name art 2>&1 | grep -v "Permission denied"
Explanation:
In short, all regular output goes to standard output (stdout
). All error messages to standard error (stderr
).
grep
usually finds/prints the specified string, the -v
inverts this, so it finds/prints every string that doesn’t contain “Permission denied”. All of your output from the find command, including error messages usually sent to stderr
(file descriptor 2) go now to stdout
(file descriptor 1) and then get filtered by the grep
command.
This assumes you are using the bash/sh
shell.
Under tcsh/csh
you would use
find / -name art |& grep ....
