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
