bash script to only execute if it finds a file

[TinTin184]

ok I have tried searching google and couldn't find anything helpful so I'm gonna try the hive mind

I'm looking for a script to check a folder for .rar files and if it finds the files to execute a script (or vis versa doesn't really matter) I thought that this script below would work but for some reason the "$?" returns "0" if it finds a .rar file or not, there may just be something wrong with the script or I might have just made a mistake somewhere and I just can't see it. Any help or input is helpful and I'm more than happy to through this script out if there is a better option available.

for filename in *.rar
do
find $2 -name '*.rar' 
if [ "$?" -ne '*.rar' ]
then
echo norar >> $2/.error
else
#run the script
fi
done
exit 0

to explain $1 is a variable passed onto the script being run if it finds a .rar and $2 is the directory eg /home/user/folder/directory.to.be.checked

find $directory_to_look_in -name -'*.rar' -exec "$script_to_execute" {}\;

Dont' understand why you need a script for this.

I had thought about that but I need the 2 outputs one for failing to find the file and one for finding it as the fail condition writes to a file in the directory which is then picked up by a web interface that shows me the files that where passed the checks and those that failed. That is why I need the script, its automated and goes off without me entering any commands, all I get is the end result once the script has run

But thanks for the idea anyway

$? returns the exit code of the last run program.

Describe what you want to do a bit more - I am still convinced that unless it's enormously complex, you can do it in a one liner.
