incremental numbering

[Pugman]

I have a problem where I need to search for "/BM /View" within a postscript file and then incrementally number each "/BM" so that the result would be like "/BM1 /View", "/BM2 /View", etc.

I have tried nl to accomplish this, but nl will corrupt any postscript file that has a photograph in it.

Please help!

How many numbers do you have to do? For example:

FCOUNT=$(HOWEVER HIGH THE BM NUMBERS GO) #Final Count

for REGEXP in ${FILES} # where FILE is what has the BM in it
do
COUNT=1
while [ ${COUNT} -ne ${FCOUNT} ]
do
grep BM${COUNT} ${REGEXP}

....commands....

let COUNT=COUNT+1
done
done


I think this is what you want to do, maybe a bit to complicated for what you need, but then I'm not quite sure on what you are doing exactly. Hope it works.

Thanks pmcmicha for your advice, but I couldn't get it to work.

I ended up using Perl to do what I needed:

perl -pi -e 's#(^\[/Dest /BM)\d+(\s+/View)# $1 . ++$count . $2#e' $file
