Im trying to come up with a way to search through player files, and match a line then take that line argument, make it an integer and see if its greater than a specific number. If it is itll delete the file. Runter was helping with this and made a script in ruby which I went off of, since I cant install ruby right now I tried converting it my way into bash but now need some help. This is what I got so far which DOES NOT work right.

#!/bin/bash
#power level check
#output=""

for f in *
do
	if [ -f $f ]
	then
		output=$f
		size=$(ls -l "${f}" | awk '{ print $5}')
		file=$(size)
	fi
	if [ -r $file ]
	then
		exec 3<&0
		exec 0<"$output"
		while read -r line
		do
			found=`expr match "$line" '(/^Plvl (\d+)/)'`
			if [[ $found =~ $line ]]
			then
                		lvl=`expr match "$found" '(\d+)/)'`
				lvl=${BASH_REMATCH[*]}
                		MIN=$lvl
                		MAX=10000
        		fi
        		if [[ $MIN -ge $MAX ]]
			then
				echo "Found match, Deleting File: $output"
				rm -f $output
			fi
		done
		exec 0<&3
	fi
	echo $file
done

My problem is it just spits out this: size: 'a.out': No such file

First, I'll say that deleting player files is bad in these days of giant disks that would hold a billion of them….

But, if you're going to anyways… why not have your MUD do it? It already knows how to read them.

Answer is install Ruby. :p

perl

But I already wrote the script for him in Ruby to do what he wants. He just has to install Ruby to use it. :p

No need for fancy scripts….

This will print filenames and level numbers that exceed 50
egrep -r -e 'Plvl[ ]+[0-9]+' . | awk "{if(\$2 > 50) {printf(\"%s %s\\n\", \$1, \$2);}}" | sed 's/:Level//'

If you wanted to remove those files, but be careful!
egrep -r -e 'Plvl[ ]+[0-9]+' . | awk "{if(\$2 > 50) {printf(\"%s\\n\", \$1);}}" | sed 's/:Level//' | xargs rm

Be sure you make backups, and if this nukes all your players, it ain't my fault. Test and fiddle until it does what you want.

Thank you quix, I knew it could be done with one of the grep functions just didnt know how.
Ran into a problem with your second one though, xargs is spitting out what egrep gives which would be ./Titan:Plvl whic is the $1 argument.

Nevermind I fixed it, sed needs to be this sed 's/:Plvl//'

I found another method btw, I took your method and added it into a bash script to see the count difference:

#!/bin/bash
echo "Checking player files…"

count=0
amount=0
for f in *
do
        if [ -f $f ]
        then
                output=$f
                ((count++))
                matched=$(egrep -e '^Plvl[ ]+[0-9]+' "${f}" | awk "{if(\$2 <= 10000) {printf(\"%s\\n\", \$f);}}")
                if [[ $matched ]]
                then
                        ((amount++))
                fi
        fi
done

echo "Found $amount matched files out of $count files"
