Re: scripting problem

IFS= InternalFieldSeperator. The value of $IFS is used by the script to seperate values from eachother.

See the difference if you use a colon

[code]
IFS=:
var=":a::b:c:::" # Same as above, but substitute ":" for " ".
output_args_one_per_line $var
#
# []
# [a]
# []
# [b]
# [c]
# []
# []
# []


You can temporarily change the value of the the IFS variable so that this doesn't happen.

[code]
ifs=$IFS
IFS='\
'
for NAMEDIR in ${DIRSTOBACKUP[@]}
do
echo $NAMEDIR
done
IFS=$ifs

How do you do that? Never heard of that before.

One way would be to set IFS (Internal Field Separator) to CR before
your loop and restore it after it.

Steve,
The easiest way to work around the space problem is to just use tar
to
backup the home directory.

#!/bin/sh
DIRSTOBACKUP=`/bin/ls -d1 /home/user/*`
for NAMEDIR in ${DIRSTOBACKUP[@]}
do
echo $NAMEDIR
done

The problem is that some of the directories have spaces in the
names. When
running the for loop, it will take the new NAMEDIR at the space.
So "Red
Hat" would end up listing as 2 directories, "Red" and "Hat". Any
way around
this?

Thanks
