convert finenames containing a numeric index from differing to fixed index-length; padding required zeroes in front of first number

export l=$1; shift; rename 'my $l=$ENV{'l'}; my $z="0" x $l; s/\d+/substr("$z$&",-$l,$l)/e' "$@"
Use it as bash-script. The first positional parameter specifies the fixed length of the numerical index. Further params specify the files to manipulate.

  • If your admin has disabled Apache's directory index feature but you want to have a cheap way to enable it for one folder, this command will just create an index.html file with a link to each file in the directory (including the index.html file, which is not ideal but makes the command much simpler). The HTML isn't even remotely compliant, but it could easily be improved on. Also, the command needs to be run each time a file is added or removed to update the index.html file. Show Sample Output

    for i in *; do echo "<li><a href='$i'>$i</a>"; done > index.html
