Hello there. I have two questions regarding Debian v.1.3.1 First of all, I'm running a 486 that has two partitions, one for MSDOS and one for linux.

If someone could give me some info or a URL, I would really appreciate that. One question: would it be possible to use a line somewhat like this: loadlin linux root=/dev/hda2 /dev/initrd=root.bin so that loadlin boots up using the linux and root.bin files? Or would it be better to use a zImage? I'm not sure what you are asking. The 'linux' file is a zImage, a compressed copy of the kernel. A bzImage is a copy of the kernel that is large enough to warrant special code to get it in memory. Also, you don't need to specify /dev/initrd=root.bin, because the kernel will load its root filesystem from /dev/hda2. My second question has to do with small shell scripts. I was reading a book on Unix the other day, and it talked about aliases, which it stated only ran under Berkely *nixes. I'm guessing that means FreeBSD, NetBSD, OpenBSD, or BSDI, but can Debian linux use aliases, too? Not to be pedantic, but aliases are a function of the shell (usually bash, but sometimes tcsh or zsh). AFAIK, bash (or whatever shell you are trying to use) runs on all of the above operating systems, so you should have no problem. The reason I'm asking is that I wrote some small shell scripts to make life a little bit easier. For example, let's say I wanted to make a program called delete that would act like this: rm -iv so that I could delete a file instead of rm'ing it, like so: $ls deletethis.zzz $delete deletethis.zzz Are you sure you want to delete deletethis.zzz? y deletethis.zzz deleted $ls $ I did that, but every time I ran delete I would get something like this: $delete deletethis.zzz Parameter not good (not verbatim, but it was close to this) use 'rm --help' for more details The same thing happened if I tried making scripts containing mv -iv and cp -iv. What is the problem here, and just as importantly, what is a posssible solution? What _exact_ commands are you using to set the aliases? P.S. I know this is probably a silly question, but if my CD-ROM drive is the second device on my first IDE Controller, would it be /dev/hdb ? Yup, you're right on the money.

To my knowledge, at least ksh, bash, zsh, and tcsh support shell aliases, and I believe traditional csh does as well. This means that these shells will provide aliases on *any* system that runs them; I routinely use aliases under zsh on Debian i386 Linux, Sun, and SGI machines. TL The reason I'm asking is that I wrote some small shell scripts to TL make life a little bit easier. For example, let's say I wanted to TL make a program called delete that would act like this: TL TL rm -iv (with a goal of being able to say delete foo and have it DTRT) Assuming what I quoted is the entire contents of the shell script, it won't do what you want. Whenever you tell the shell delete with any parameters, it runs rm -iv with no parameters. The equivalent shell script would be #!/bin/sh rm -iv $* (The $* expands to all of the arguments passed on the command line.) You could also do this with aliases: alias delete='rm -iv' Then the shell replaces delete on the command line with rm -iv, so delete foo gets replaced with rm -iv foo, which is what you want. TL P.S. I know this is probably a silly question, but if my CD-ROM TL drive is the second device on my first IDE Controller, would it be TL /dev/hdb ? Yes. You can forget this if you make a symbolic link called /dev/cdrom which points to hdb, and then just use /dev/cdrom when you want your CD-ROM. -- David Maze [EMAIL PROTECTED] http://donut.mit.edu/dmaze/ Hey, Doug, do you mind if I push the Emergency Booth Self-Destruct Button?
