mkisofs -o myiso.iso `cat filelist.lst` not working

Xeratul · 07-06-2011, 02:55 PM

Hello,

I have found today some problem with the following command:

Code:

mkisofs -o myiso.iso   `cat filelist.lst`

There are two issues. The first one is spaces, and the second one is that the files have a CR+LF in there for each files.

the filelist.lst have the files like ls -1 with separation by LF.

Cheers

mkisofs accepts a single directory as an argument, not a list of files.

BTW, use $() instead of backticks. They can't be confused with single quotes, and they're easier to nest.

thanks. I tried but it failed too

Code:

mystring=""
while read each
do
    mystring="$mystring $each"
done<"filelist.lst"
mkisofs -o myiso.iso "$mystring"

How is that different from supplying a list of files directly on the command line?

This should work, though:

Code:

tmpdir="/tmp/${RANDOM}-$(date +%s)"
mkdir tmpdir
while read file
do
    cp -R "$file" "$tmpdir"
done < filelist.lst
mkisofs -o myiso.iso "$tmpdir"
rm -r "$tmpdir"

thank you! this method however copy the data in a temp folder. I avoid the issue regarding the input of "file1" "fil2" "file3" over mkisofs -o myiso.iso # here all the file names with "-" and separated with a space... I would rather avoid cp...

That sentence doesn't make any sense at all.

cp has no problem with filenames that have spaces, is that's what you're thinking. If you're worried that a filename begins with "-", then replace the cp line with this:

Code:

cp -R -- "$file" "$tmpdir"
