Performing Script on Multiple Files
Dear All

I have group of files named :

CDR.1,CDR.2.,CDR.3,CDR.4,CDR.5,CDR.6,etc.......

I am performing an awk command look like this : nawk -f script CDR.*

What i want is that i want to perform this command on range of files not all of them.

Instead of writing CDR.* i want to write from CDR.1 to CDR.3.

Please Advise
Best Regards
Zanetti

Try CDR.[1-3]

Handle three at a time, for as long as there are any left?

Code:
echo CDR.* | xargs -n 3 nawk -f script

Hi.

The order of the files produced by the shell may not be what you expect, so use caution if the order is important. For example:
Code:
#!/bin/bash3 -

# @(#) s1       Demonstrate list sequence from shell for numeric sub-strings.

echo
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1)
echo

# Manufacture the list, and remove previous debris.
LIST=$( printf "t%d " {5..12} )
rm -f $LIST

# Create the files.
touch $LIST

echo ' Results from echo t*:'
echo t*

exit 0

Producing:
Code:
% ./s1

(Versions displayed with local utility "version")
Linux 2.6.11-x1
GNU bash 3.00.16(1)-release

 Results from echo t*:
t10 t11 t12 t5 t6 t7 t8 t9

Best wishes ... cheers, drl
