oh btw - When you send in the -exec command with the ls -(options) command, why do you need to add the "{} \;"?
The {} gets replaced with the found file's name, and the \; shows where the -exec command line ends, so you can continue to specify other options to find.
You could even have multiple -exec actions:
Without the \; how would you know where the first -exec command ends and we are back in find's command line proper again? The command you -exec could even be another find so looking for familiar options is not a good way to disambiguate; and besides, other programs than find have options like -type and -name too.
Having said that, -exec is usually the last thing you do, and the file name of the found file is usually the last thing in that command line, so it does seem a bit redundant in those cases. A common exception would be the mv command where the found file is usually the thing you want to move.
I want to get the file which created the error when the find command was run ?

open
OPENVT(1) Linux 1.x OPENVT(1)NAME
openvt - start a program on a new virtual terminal (VT).
SYNOPSIS
openvt [-c vtnumber] [OPTIONS] [--] command
DESCRIPTION
openvt will find the first available VT, and run on it the given command with the given command options, standard input, output and error
are directed to that terminal. The current search path ($PATH) is used to find the requested command. If no command is specified then the
environment variable $SHELL is used.
OPTIONS
-c, --console=VTNUMBER
Use the given VT number and not the first available. Note you must have write access to the supplied VT for this to work;
-f, --force
Force opening a VT without checking whether it is already in use;
-e, --exec
Directly execute the given command, without forking. This option is meant for use in /etc/inittab. If you want to use this feature
in another context, be aware that openvt has to be a session leader in order for -e to work. See setsid(2) or setsid(1) on how to
achieve this.
-s, --switch
Switch to the new VT when starting the command. The VT of the new command will be made the new current VT;
-u, --user
Figure out the owner of the current VT, and run login as that user. Suitable to be called by init. Shouldn't be used with -c or -l;
-l, --login
Make the command a login shell. A - is prepended to the name of the command to be executed;
-v, --verbose
Be a bit more verbose;
-w, --wait
wait for command to complete. If -w and -s are used together then openvt will switch back to the controlling terminal when the com-
mand completes;
-V, --version
print program version and exit;
-h, --help
show this text and exit.
-- end of options to openvt.
NOTE
If openvt is compiled with a getopt_long() and you wish to set options to the command to be run, then you must supply the end of options --
flag before the command.
EXAMPLES
openvt can be used to start a shell on the next free VT, by using the command:
openvt bash
To start the shell as a login shell, use:
openvt -l bash
To get a long listing you must supply the -- separator:
openvt -- ls -l
HISTORY
Earlier, openvt was called open. It was written by Jon Tombs <jon@gtex02.us.es or jon@robots.ox.ac.uk>. The -w idea is from "sam".
