diaplay number of lines as a header record 1

[navink123]

Hi Guys,

I am extracting data from a table and putting it into a number of text files. While doing this I am displaying the number of records in the file, on the top of the same file as a header record. I am using a modified version of the following script posted by Dickiebird to achieve this.

But the number displayed needs to be a 10 digit number. In case the digits are less than 10, the number needs to be prepended with remaining zeros to make it 10.

Can anybody please help me with this.

Thanks,
Navin

Forgot to paste the script

Thanks,

The existing script is as follows:

for file in *
do
lines=`wc -l $file`
( echo "Lines in file = $lines" ; cat $file ) > tmp$$
mv tmp$$ $file
done

Instead of using echo use:

[tt]printf "Lines in file = %010d\n" $lines[/tt]

This might sound dumb, but try the following,

do a math manipulation:
x 3 33 333
y=10000000000+x
y 10000000003 10000000033 10000000333

use cut to get ride of the leading 1

lines=`printf &quot;%010d&quot; &quot;$(wc -l < ${file} )&quot;`

Annihilannic's one liner is way too cool

Vger's is even cooler.

If you're using the Korn shell, you can use &quot;[tt]typeset[/tt] to format a variable.

#!/bin/ksh

typeset -RZ10 lines

for file in test.dat
do
  lines=$(wc -l < $file)
  ( echo &quot;Lines in file = $lines&quot; ; cat $file ) > tmp$$
  mv tmp$$ $file
done

The &quot;[tt]-RZ10[/tt]&quot; sets [tt]lines[/tt] to be Right justified, Zero filled, and 10 characters wide.

Hope this helps.

That's Cool too, Sam.
