Hi David and All,

Yep, #1 was me, and making the same initial troubleshooting inquiry.

I had to send a chuckle back to Michael that, even though I had to ask for troubleshooting purposes, I too have an ll set up for myself... :o)

For those using unix and wondering what we are talking about regarding aliases, normally ll is not a unix command, however users can make their own in their Bourne/C/Korn shells in the startup file such as .cshrc or .kshrc, etc. You can make them in a couple ways: 1) make your own script file and make sure it is in your path, 2) make your own executable and make sure it is in your path, 3) check out the "alias" command, or 4) add into your .kshrc (or other startup file depending on the shell you have in use) the defining of a script function, such as:

ll() { echo "`pwd`:" ls -ilsa $* }

which, since it is in your shell environment, you do not need to worry about having something found in your path, and it will be there until you log off. The $* allows for the passing of additional flags or file specs, etc., just as if you sent them to the ls command (which eventually it really is).

Hope this is helpful.

Yep, #2 was me. I was trying to suggest, in my usual subtle way (where 'subtle' is defined as 'less impact than a two-train collision') that perhaps the poster was using his own alias and there was no way for anyone to know exactly what *his* 'll' was likely to do. It might be 'ls -l', but it might not...
