Perl/cgi puzzle

[tonybear]

I have set up a guestbook before and altered settings in cgi-bin. Now I am trying something a little harder (a shopping cart for http://www.atsbargains.com) and I have hit a wall trying to figure out this instruction:

"Set the permissions of the cart.cgi and cartmanager.cgi script to rwxr_x_r_x."

Could someone break this down in simpler language for me?

Unix permissions.

r=read
w=write
x=execute

rwx------ the first three chars are user
---rwx--- the next three chars are group
------rwx the last three chars are other

so, rwxr-xr-x means you want read, write, and execute permissions for the file's owner, and read/execute for everyone else.

the command for this would be
chmod 755 cart.cgi
chmod 755 cartmanager.cgi
