Any help for this script appreciated

This the script to delete files older than 240 days.
#!/usr/bin/sh
find /tmp -mtime +240 -exec rm {} \;

Hi Rajesh,

I am not an expert in scripting but it should work.
===========================================
#!/usr/bin/sh
read var1
echo $var1
find /tmp -mtime +$var1 -exec rm {} \;
exit
===========================================

HTH,
Devender

Rajesh,
I think what Devender has suggested should be fine. Since you have mentioned you want to pass the value interactively, here is a modification
#!/usr/bin/sh
echo "Please enter the number of days: \c"
read var1
echo "files older than $var1 days will be deleted "
find /tmp -mtime +$var1 -exec rm {} \;
exit

thanks

I would actually go one step further:

#!/usr/bin/sh

echo "Please enter the age of files you want to delete in days:"
read DAYS

find /tmp -mtime +${DAYS} -type f -exec ls -ld {} \;

echo "Are you sure you want to delete all of these files?"

read ANSWER

if [[ ${ANSWER} = "Y" -o ${ANSWER} = "y" ]] ; then
find /tmp -mtime +${DAYS} -type f -print -exec rm -f {} \;
fi


This script will first list the files you want to delete and then prompt you to make sure you want to delete them. If you answer with anything other than Y or y, then it won't delete the files.

It looks like you need to pass many values.
That's why you need to pass them interactively.

Just add a while loop in Patrick's script

echo "Continue"
read choice
While ($choice='y')
Patric's script
read choice
done

You can try by setting an environment variable as #export FINDDAY=240
#find /tmp -mtime +${FINDDAY} -exec rm {} \;

If you want to change it then,

# export FINDDAY=100

hth.

My approach to this would not be asking the user or setting an environment variable but simply passing in the argument on the command line --- and like real UNIX applications, it assumes that the users knows what he is doing and doesn't ask confimation questions.

#!/usr/bin/sh

PROG=${0}
typeset -i STAT=255
if [[ ${#} -ge 1 ]]
then
typeset -i DAYS=${1}
shift
find /tmp -mtime +${DAYS} -exec rm \;
STAT=${?}
else
echo "Usage: ${PROG} requires 1 arg." >&2
fi
exit ${STAT}

You would use it like this:
myscript.sh 100

If you like, you could write another little script that prompts for the value and then pass this value into myscript.sh.
