Another solution ( ksh or bash) :
Code:
# Script file: concat.sh
shopt -s extglob # Not need for ksh
src_prefix=File
out_prefix=Total
typeset -i src_seq out_seq
for src_file in ${src_prefix}+([0-9])
do
src_seq=${src_file#${src_prefix}}
(( out_seq=src_seq/10+1 ))
echo "cat ${src_file} >> ${out_prefix}${out_seq}"
done
Execution:
Code:
$ ls File*
File1 File100 File11 File19 File2 File9 File91 File92 File99
$ concat.sh
cat File1 >> Total1
cat File100 >> Total11
cat File11 >> Total2
cat File19 >> Total2
cat File2 >> Total1
cat File9 >> Total1
cat File91 >> Total10
cat File92 >> Total10
cat File99 >> Total10$
