re: how do I open file from command line


Oh the shame of it!!

How do I open grub.conf from the command line? I know how to cd there (cd /etc), but don't know how to open the file from the prompt. Too dependent on gui.

Thanks,

You need to use an editor like vi, emacs,joe, jove (there are plenty)

General syntax (vi can be substituted with any editor you choose):

$ vi <file-to-edit>

PS:

Can I edit a file through 'cat'?
Command line access was because I had to su to get there, and I didn't want to log-off and then log-on as root.

Yeah - cat > file
then just type until done and hit ctrl-d. And I'd use less to view it because, well, less is more.

Not sure I followed the last bit, but you can launch an X app as root from an xterm.

-- Duh - you can *create* a file with cat. To edit it, you'd have to use ed or sed. *g*

One small other nitpick:

cat > file => creates the file or overwrites, so you always start with a empty file.

cat >> file => append to file or create if it doesn't excists.
