Copy every nth file

English Programming/Scripting
#1

Hi!

I want to create a bash script which should do something to every nth file in a directory, i.e. copy. The script I got so far looks like this:

#! /bin/sh

for F in *.ifd
do
echo copying: $F
done

But now it just copies every file. Now I want it to copy only every 2nd file for example. What would the approach be for that?

Kind regards,

Phong

Dirty hack:

<code interpreter="/bin/bash">
#!/bin/bash
ctr0=0;
for F in *.ifd; do
if $ctr0 = 0 ] ; then
let ctr0=$ctr0+1 ;
echo $F;
else ctr0=0;
fi
done
</code>

Good luck.
