Security Issue with Standard Input?
Hi Gang,

Running a script in AIX 5.3. Users wanted me to add a "confirm you want to run script, enter 'y' or 'n'" kind of thing... here is what I came up with:

#!/bin/sh

myfile=`basename "$1"`
dateNow=`date "+%m.%d.%Y.%H.%M.%S"` # Get current date
mydatedfile=$myfile.$dateNow
appfolder="/home/43168134/prod"
newfolder="/home/43168134/arch"

echo "Are you sure you want to approve $myfile ?"
echo ""
echo "Okay?("Y" or "N")=> "
set ret = "$<"
if ("$ret" != "y" && "$ret" != "Y") then
echo ""
echo ""
echo "End."
exit 0
else
if [ -s "$myfile" ]; then
mv "$myfile" "$appfolder/$myfile" # Move file to another folder
cp -p "$appfolder/$myfile" "$newfolder/$mydatedfile" # Copy file with new archive name
print "$myfile has been moved to Production and Archived."
else
print "$myfile does not exist or is empty."
exit 1
fi
fi
exit 0

When I run the script, I get this:

$ approveTEST.sh CallidusFile3.csv
Are you sure you want to approve CallidusFile3.csv ?

Okay?(Y or N)=>
approveTEST.sh[13]: : 0403-006 Execute permission denied.
CallidusFile3.csv has been moved to Production and Archived.

The script does the move/copy OK, but won't accept any input and instead gives me an error. I did chmod 755 and 744 hoping that would fix it, but no luck.

Any thoughts?

Thanks in advance...

uudemon.cleanu

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
