Split the name to 2 parts

[GVishnu]

Hi All,

Could you please help me out here!

Issues:
I have the file name like A4LNEU__20061123. I would like like the split the name of the file to 2 parts. Each part should have only 4 characters.
like:
Part1:A4LN
Part2:EU__

I need to redirect the out put to one more file.

Please help me out to resolve this issue.

Many Thanks,
Vishnu.

eg in bash interaction

# var=A4LNEU__20061123
# var1=$(expr "$var" : '\(.*__\)')
# echo $var1
A4LNEU__
# lenvar1=${#var1}
# lenvar1half=$((${#var1}/2)) #depending on whether you know the length 
# first=${var1:0:$lenvar1half}
# second=${var1:$lenvar1half}
# echo $first $second
A4LN EU__

echo A4LNEU__20061123 | sed -r 's/^(....)(....).*$/\1\n\2/'

You can then redirect result into a file using '>' redirection.
