I'm just looking for a better understanding on how to use xterm. it feels alot like dos but it has been so long since i used dos i find myself unable to use a great application like xterm. if there is some info i could read that explains what xterm can do and how to use it efficiently i'd really appreciate the help, thank you.

your question asks a lot more than you might think it does...

as such, I'll recommend you read http://oreilly.com/catalog/9780596009304/index.html then come back with any questions you might have.

Also, if you can't find the book in a local library and you don't feel like shelling out $40 for it, try this site someone pointed me to:

A regular Linux system will use Bash as a shell (a shell being the program that interprets commands entered in a terminal). And many utilities will come from the GNU Project. The 770/N8X0 use the simpler BusyBox instead of those, but much of the Bash and GNU utility documentation still applies. For example, the Linux Documentation Project's Bash Guide for Beginners (http://tldp.org/LDP/Bash-Beginners-Guide/html/index.html).

This is not tailored to the IT, but still a useful reference:

I hope this helps,

what i'm looking to do is basically save space on my main device by putting programs into mmc1 & mmc2, i have attempted to put stuff onto these internal and external cards but i don't fully understand the comands i put into xterm. i follow the inputs needed to accomplish it through xterm but when i read what is typed i see spaces imbetween commands like cd -xzcf /usr/. and i'm not sure why that is. when i attempt to replicate what others suggest it appears to not read the infofrom the commands entered. so all i want to do is run programs that i put into files saved into my internal/external cards and run the programs through xterm.

is this a function that is difficult? it seems easy to do because the steps don't change much. any advice?

What you're referring to is moving programs and their respective data files to your MMC card and then soft-linking them into your /usr/ directory.

This is actually really difficult to do, surprisingly... mostly because your MMCs are probably formatted as FAT and your internal flash is j2ffs. And "ln" won't allow symlinking between differently formatted memory (in my experience, correct me if I'm wrong)

You might instead look into cloning your file system to one of your MMC cards to just give you more room on your normal operating system and then you won't have to mess around with this stuff :) search this forum for "boot from SD"

xterm is a window in a X environment like a window in MS windows XP for example. In that windows you can use many commands with many options to do your tasks; with mistakes you can bring down the machine if you have privileges to do so.

Even we are at this point; machines are still not there yet in order to know exactly what we want; therefore, commands have to be clear. So there come those spaces between commands and their options.

Actually you can save space by moving lot of functions to mmc1 or mmc2. But are you prepared to what would happen if you forget and take out the mmc1 while the IT is using it ? Do you know how to fix after that?

That's why you should read more about how to clone the SD that is a way to move the whole thing out from flash to the mmc.

Try to use the search function and you will learn more.

And "ln" won't allow symlinking between differently formatted memory (in my experience, correct me if I'm wrong)Symlinks (or soft links, created by "ln -s") can point anywhere from a Linux filesystem. So, there should be no problem moving large files from a Linux filesystem to a FAT filesystem, and replacing them with symlinks.

Hard links (created by "ln") cannot span filesystems at all, even if they're the same type.

as much as i don't mind trying some of the ideas here i like a good challenge too, so the whole xterm program is something i would like to learn despite any difficulties towards hours of playing with it (i don't fustrate that easy), so if i need to reformat my mmc1 i will, i learn quick just looking for a little advice. thank you for all anyone has given, it gives me more to learn from. hope to return the favor.
