Output of ls command in octal

[pwilliams]

Some time ago I copied a bash shell script from a site which I cannot trace. It was written in bash and awk and was not good but superb ! It was about 25 lines long. I had made it into a function and was using it regularly but in a change of distro I lost it . Can anyone help?

@pwilliams,

Can you give us an example of what the script did?

Your description isn't very clear. We know something about processing ls output into octal. However a concrete request might help.

I believe you need output permissions in octal format ?

for example if original output is:

-rw-r--r-- 1 root root    24405 Sep 20 16:56 a.txt

you need it like this:

644 -rw-r--r-- 1 root root    24405 Sep 20 16:56 a.txt

If this is what you wanted then you can use;

ls -l | awk '{k=0;for(i=0;i<=8;i++)k+=((substr($1,i+2,1)~/[rwx]/)*2^(8-i));if(k)printf("%0o ",k);print}'

Oralloy ,ashitpro many thanks for your replies.
With a red face I must confess,the file came to light in a totally wrong directory , on a usb stick I had forgotten about.Would anybody be interested in seeing it?

send the function you are talking about.

function lso {
ls -l | awk '{
    k = 0
    s = 0
    for( i = 0; i <= 8; i++ )
    {
        k += ( ( substr( $1, i+2, 1 ) ~ /[rwxst]/ ) * 2 ^( 8 - i ) )
    }
    j = 4 
    for( i = 4; i <= 10; i += 3 )
    {
        s += ( ( substr( $1, i, 1 ) ~ /[stST]/ ) * j )
        j/=2
    }
    if ( k )
    {
        printf( "%0o%0o ", s, k )
    }
    print
}'
}

function lsa {
ls -al | awk '{
    k = 0
    s = 0
    for( i = 0; i <= 8; i++ )
    {
        k += ( ( substr( $1, i+2, 1 ) ~ /[rwxst]/ ) * 2 ^( 8 - i ) )
    }
    j = 4 
    for( i = 4; i <= 10; i += 3 )
    {
        s += ( ( substr( $1, i, 1 ) ~ /[stST]/ ) * j )
        j/=2
    }
    if ( k )
    {
        printf( "%0o%0o ", s, k )
    }
    print
}'
}

Similar but different.
