This is a script which you can use to call SJBsplit:
#!/bin/bash
# split files into single Freqencys
# calls "sjbsplit"
# output: *.000 to *.255
#
SAVEPATH=./split
mkdir $SAVEPATH
for FILE in *.pre
do
echo sjbsplit $FILE
bunzip2 -k -c $FILE | sjbsplit $FILE
COUNTER=0
while [ $COUNTER -lt 256 ]; do
cat $FILE.$COUNTER.temp | bzip2 >$SAVEPATH/$FILE.$COUNTER
rm $FILE.$COUNTER.temp
let COUNTER=COUNTER+1
done
done
