Multiple file needed with certain file_prefix
Hi Guys,

Can I please ask for help? I hv one single file in which contains lines

abc|456|xyx|56475
efg|56758|iew|8938
:
:
:
:
:
zzz|999|fdfj|nnnop

I'm going to break them into small files in which each file contains only single line. And each file should have the prefix as such Mone_<yymmddhhmmss>.vob

What have you tried so far?

Partial solution is:

Code:
$ awk '{print > "file_" NR}' rau.txt

Putting the date format (as you asked) in filename can be done using system, I am also trying, will update if succeed.

this will help you to process one line at a time:
Code:
for line in `cat filename`
do
    echo $line
done

instead of echoing to terminal, write the line in a new file

I think this may work.

typeset -i ln
ln=`cat any | wc -l`
echo $ln
typeset -i n=1
while [ $n -le $ln ]
do
file_nm=`date "+%d%m%G%H%M%S"`
head -$n any | tail -1 > Mone.$file_nm.vob
sleep 1
n=`expr $n + 1`
done

Hi Siba,

But look pretty strange the file result turns out such, and it only echo what <file name> to final Mone.%file_nm.vob

$ cat Mone_20080527165446.vub

Hi jaduks,

split -l 1 3.unl

ls x?? > file

for x in `cat file`
do

awk '{print > "Mone_$_date.vub" NR}' $x
done


Strange this is Mone_$date.vub1 having the last line
