“755”-style permissions with ‘ls’
After a quick Google search for “ls permissions octal” I found a very handy alias to put in my .bashrc. Not only is it handy to see the OCTAL value of the permissions for each file/dir, it will undoubtedly help you more quickly recognize/interpret the normal ls -al output.
Example usage:1alias lso="ls -alG | 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}'"
You can also type (or paste) this slightly different version into terminal:1234mycomp:~ adam$ lso755 drwxr-xr-x 15 adam staff 510 Dec 6 02:47 .vim644 -rw-r--r-- 1 adam staff 1136 Dec 18 16:55 .vim_mru_files600 -rw------- 1 adam staff 13665 Dec 18 16:56 .viminfo
1ls -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}' -
Creating a Module (D6)
This example shows how to create a custom module for a site. We typically create one custom catch-all module that we can use for one-off site customizations where we don’t need to create a unique module. If they are general site tweaks that cannot go in template.php, we put them here. Please read the book Pro Drupal Development for a much better understanding of how all of this (and everything else Drupal) works! DrupalBook.com. It is an amazing reference tool for daily usage, as well as a complete walk-through of how to take advantage of the power of Drupal.
