I have something for the PLUG Website that should be of interest to
newbies and possbly even old-farts such as myself. For some years I've slowly
accumulated a list of notes on doing various things in Linux. I think of it
as my personal "big dummy" list -- it's how to do various things that I don't
do often enough to memorize. Some of the things go in categories (setting up
CUPS, printers and printing files in various ways) and some things end up in
a "one-liners list" of simple, one-line commands for various purposes.
Some are entries gleaned from this mailing list, by the way. (Thank you!)
I'm looking for a "good place" on the PLUG website but the content
crosses the boundary between FAQ (or more likely, "Not So FAQ But Wish I
Had") and something in the Downloads which, unfortunately, ends up somewhat
buried and hidden.
Where do you think it should go?
Here's a brief sampling:
Abbreviated version
EdskiHowTo.txt: How To Do Things I Sometimes Forget How To Do
No warranty, no guarantees, etc...
Indeed, if you blindly follow the instructions herein, you will almost
certainly destroy your system. Have Fun!
Add edski (me) to sudo database
As root, edit /etc/sudoers (should be one there already)
After the line about root, add a new line (with no leading whitespace):
edski ALL=(ALL) NOPASSWD: ALL
vi Tricks
ma # "Mark" the current line as "a"
'a # Go to mark "a"
:'a,. !sort # Alpha-sort the lines between mark "a" and "." (here)
Allow anyone to mount the first USB storage device (such as a digital camera)
As root
mkdir /mnt/usb
Edit /etc/fstab: add the following (but no leading whitespace)
/dev/sda1 /mnt/usb vfat noauto,user 0 0
Then, as a normal user
Ready the USB storage device
[Put the camera into playback (not record) mode]
[Maybe wait several seconds before attempting the mount?]
[fdisk -l /dev/sda1 # (May be helpful?)]
mount /dev/sda1 # OR mount /mnt/usb
find /mnt/usb -print # See what's there
... whatever (such as "cp /mnt/usb/... elsewhere"
umount /dev/sda1 # OR umount /mnt/usb
Various single-Line Commands
INDEX=22; sed -n "${INDEX}p" filename # Print one line from a file
fdisk -l /dev/hda # (May be informative)
pushd .; cd elsewhere; do some stuff; popd # go back, can be multi-line
( cd elsehwere; do some stuff ) # Equivalent, must be done as one line
fuser filename # Show PIDs having filename open
fuser -k filename # Kill processes having filename open
fuser -k /dev/dsp # Kill processes using sound card
ps xaf # Show all processes with parentage
find BB PT -print | zip music -@ # Create music.zip for a Windows system
a2ps -1 file # Print file (1-up)
a2ps -4 file # 4-up print file (text, postscript, PDF, whatever!)
a2ps --portrait --columns=1 filelist # 1-up print lots of files
a2ps --delegate=off file # Print plain ASCII regardless of content/name
