First I just thought to add an alias, but then I found myself scripting...

In case anyone finds this useful... Does it work on DSL?

Code Sample

#!/bin/bash

# Bash script for making CD-images out of files and/or directories easily.
# Burned images should work with old CD drives as well with new ones
# and with many OS:es too.
# May not work if you specify multiple files/directories to add... But should.;)

if [ -z "$1" ]
then
echo "Nothing to do. --help for help." >&2
exit 1
fi

case $1 in
--help)
echo -e "USAGE: `basename $0` [-bz] <imgfile> <contents for ISO image>\n -bz makes image compressed."
echo "If \"imgfile\" is -, then output will be directed to stdout."
;;
*)

if [ -z "$2" ]
then
echo "Missing arguments." >&2
exit 1
elif which mkisofs &> /dev/null
then

MKISOFSOPTS="-JR -file-mode 0444 -dir-mode 0555"

case $1 in
-bz)
# Zipping

BZIPCOMMAND="bzip2 -vzc9"

if [ -z "$3" ]
then
echo "Missing arguments." >&2
exit 1
elif ! which bzip2 &> /dev/null
then
echo "bzip2 isn't in your \$PATH or isn't installed. Do not use -bz option" >&2
exit 1
elif [ "$2" != "-" ]
then
DESTFILE="$2"
shift
shift
# To file
mkisofs $MKISOFSOPTS $@ | $BZIPCOMMAND > $DESTFILE
else
# To stdout
shift
shift
mkisofs $MKISOFSOPTS $@ | $BZIPCOMMAND
fi
;;
*)
# No zipping
DESTFILE="$1"
shift
case $DESTFILE in
-)
# To stdout
mkisofs $MKISOFSOPTS $@
;;
*)
# To file
mkisofs $MKISOFSOPTS -o $DESTFILE $@
;;
esac
;;
esac
else
echo "mkisofs isn't in your \$PATH or isn't installed." >&2
exit 1
fi
esac

I'd add a size limit there if I knew the precise size of 650Mb CD. Anyone know this?
Or any other suggestions?

I found a quite good page about the actual size of CD.

Here's in short:

Quote

Spelled out simply:

21 minutes == 94,500 sectors == 184.6MB CD-ROM == 212.0MB CD-DA
63 minutes == 283,500 sectors == 553.7MB CD-ROM == 635.9MB CD-DA
74 minutes == 333,000 sectors == 650.3MB CD-ROM == 746.9MB CD-DA
80 minutes == 360,000 sectors == 703.1MB CD-ROM == 807.4MB CD-DA
90 minutes == 405,000 sectors == 791.0MB CD-ROM == 908.4MB CD-DA
99 minutes == 445,500 sectors == 870.1MB CD-ROM == 999.3MB CD-DA

What about DVDs then?

You can also use single quotes so that you don't have to escape certain characters on your output strings.

Any reason for making this a bash-specific script?

I could add DVD image creating too.
Anyway. I designed this script primary for myself. Later I decided to share this.

Bash is common and I don't know much perl or any other language suitable for this. Well... I could do this with php, but then there would be php depency. ;P

I guess hats meant it has some bash-specific syntax, so it might or might not work with ash, dash, lash, etc. other shells. Though bash is a standard component, so you're likely to find it on any linux system.
