I don't know why ou'd really need to do #2, and I'm not totally sure what a portable way to do it would be. Normally, you need PATH, LD_LIBRARY_PATH, but scores of environment variables are needed by different commands.
#3 unset IFS
#4 you dont have to check the return code per se; you can set up an execution chain, and if anyone breaks, there's been an error:
Code:
cd /var/www && rsync . /new/dir && cp /something /new/dir
#5 yes. Use "$@" when referring to the entire argument list and "$var" in almost every case. (Sometimes you need to use single-quotes, sometimes you want to let it expand with spaces and you want no quotes).
#6 uh, whatever. syntax and indentation aren't standard. Two common ways:
Code:
if [ "go" = "$1" ] ; then
while [ -f /var/lock/status ]; do
run_command
done
fi
And
Code:
if [ "go" = "$1" ]
then
while [ -f /var/lock/status ]
do
run_command
done
fi

- points in map view (no 3D view)
- color of each point should depend on its z-value.
- I want to define my own color scale

hi,
I believe a mount point does not have to be a physical disk, but rather a logical one? Is this correct? if so, how can I find out if my mount points are on different physical disks?
thanks (9 Replies)

Combine points of specific key (a1) based on user defined size (lets say 200 in this example).
so a1 191 and 191+200 and sum of all the values (4th column)
and vice versa...
Thanx a bunch!
a1 191 201 1
