Script that lists #of permissions

nabil · 04-21-2002, 06:31 PM

what should be the script that lists the number of readable, writable and executable files in your home directory. ??

Example:

$filenum
There are 5 executable files
There are 3 writable files
There are 4 readable files

Thanks for any help

Maybe something like this:

Code:

#!/bin/bash

dir=~

readable=0
writeable=0
executeable=0
count=0

for file in `ls $dir`
do
  if [ -r $file ]
  then
    let readable+=1
  fi
  
  if [ -w $file ]
  then
    let writeable+=1
  fi 

  if [ -x $file ]
  then
    let executeable+=1
  fi

  let count+=1
done

echo "$count file(s)"
echo "There are $readable readable file(s)"
echo "There are $writeable writeable file(s)"
echo "There are $executeable executeable file(s)"

Thank you,
That was pretty good ...Did just exactly what I asked for..

Just curious,

Your script kind of came late as I had to think to make one my self.
I thought some thing along these lines:

Code:

This will give you number of files with readable permission 
Code: 
ls -l | grep "r" | wc |awk '{print $1}'  

This will give you number of files with writable permission 
Code: 
ls -l | grep "w" | wc |awk '{print $1}'  

This will give you number of files with execute permission 
Code: 
ls -l | grep "x" | wc |awk '{print $1}'

What do you think,
Does it do the job too, not sure if it works every time.

It might not work if the executable file has a w in the name it'll count it as writable, it will give you 1 file if run it against writable file check, and so on.

Like neo said if the name, user or group has a r w x in it then your count will be inaccurate. You could have modified it to something like this to make sure it only checks the permissions:

ls -l | cut -f 1 -d ' ' | grep r | wc | awk '{print $1}'

why are you using something as big as awk to do something so simple? just use "wc -l" instead.
