But it is not working either. Only the first instance is starting. Is there any way to execute without using find.

Please use code tags next time for your code and data. Thanks
What you are doing makes absolutely no sense to me!
I repeat: How many hundreds of times do you want to execute these two commands? Please explain in English why you want to run so many identical copies of these commands.
Do these commands need to be given the pathname of a directory as an operand?
What exit code do these commands return when run from the command line without find?
Hi , I write a script like this\ and put it under / (root) :

It would be helpful if someone could help me out here. The problem I have been having is that I cannot run some commands which are valid - whenever I try to run the command I get the message "command not found". Now, if I run the same command as root it executes. These commands do not have to be... (5 Replies)

I can't get this to work. Running a single command works fine:
find . -name "*.dat" -exec wc -l '{}' \;
gives me the file name and number of lines in each .dat file in the directory.
But what if I want to pipe commands, e.g. to grep something and get the number of lines with that pattern... (3 Replies)
Hi Gurues,
I need to modify an existing script that uses find to search a folder, and then move its contents to a folder. What I need to do is run gzip on each file after it's moved.
So, I ran this little test:
Put a ls.tar file on my $HOME, mkdir tmp, and then:
virtuo@tnpmprd01: find .... (3 Replies)
Hi all,

Hi Folks -
Is there a way to add two execs to one script? For instance, I need to redirect the stdout and stderr to two separate directories. I want to do this:
#::-- Direct STDOUT and STDERROR to repositories --::#
exec 2>"${_ERRORFILE}" > "${_LOGFILE}"
exec 2>"/new/path/file.err" >... (7 Replies)

setuid
SETUID(1) General Commands Manual SETUID(1)NAME
setuid - run a command with a different uid.
SYNOPSIS
setuid username|uid command [ args ]
DESCRIPTION
Setuid changes user id, then executes the specified command. Unlike some versions of su(1), this program doesn't ever ask for a password
when executed with effective uid=root. This program doesn't change the environment; it only changes the uid and then uses execvp() to find
the command in the path, and execute it. (If the command is a script, execvp() passes the command name to /bin/sh for processing.)
For example,
setuid some_user $SHELL
can be used to start a shell running as another user.
Setuid is useful inside scripts that are being run by a setuid-root user -- such as a script invoked with super, so that the script can
execute some commands using the uid of the original user, instead of root. This allows unsafe commands (such as editors and pagers) to be
used in a non-root mode inside a super script. For example, an operator with permission to modify a certain protected_file could use a
super command that simply does:
cp protected_file temp_file
setuid $ORIG_USER ${EDITOR:-/bin/vi} temp_file
cp temp_file protected_file
(Note: don't use this example directly. If the temp_file can somehow be replaced by another user, as might be the case if it's kept in a
temporary directory, there will be a race condition in the time between editing the temporary file and copying it back to the protected
file.)
