BASH script: Downloading consecutive numbered files with wget

#!/bin/sh

if [ $# -lt 3 ]; then
        echo "Usage: $0 url_format seq_start seq_end [wget_args]"
        exit
fi

url_format=$1
seq_start=$2
seq_end=$3
shift 3

printf "$url_format\\n" `seq $seq_start $seq_end` | wget -i- "$@"

Save the above as seq_wget, give it execution permission (chmod +x seq_wget), and then run, for example:

$ ./seq_wget http://someaddress.com/logs/dbsclog01s%03d.log 1 50

Or, if you have Bash 4.0, you could just type

$ wget http://someaddress.com/logs/dbsclog01s{001..050}.log

Or, if you have curl instead of wget, you could follow Dennis Williamson’s answer.
