Running md5sum on a list of files
Hello,

I would like to run md5sum on a list of files saved in a text file, and save the result in another file. (ie. md5sum `cat list.txt` > md5list.txt)

I have tried several things, but I am always confronted to the same problem: some of the filenames have spaces.

I have run sed on the list to escape all the spaces, but shell still considers them as parameter separators.

How would you do that ?

Thanks !

gst-md5sum-0.8

gst-md5sum-0.8(1)						   User Commands						 gst-md5sum-0.8(1)

NAME

       gst-md5sum-0.8, gst-md5sum - get an md5sum of a GStreamer pipeline through md5sink

SYNOPSIS

       gst-md5sum-0.8 [--verbose] [gst-std-options] [partial-pipeline-description]

       gst-md5sum [--verbose] [gst-std-options] [partial-pipeline-description] [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-md5sum-0.8 generates MD5 checksums of the data generated by a GStreamer pipeline.

       In theory, both of the following commands should print out the same checksum:

       gst-md5sum-0.8 filesrc location=music.mp3

       md5sum music.mp3

       If  the	pipeline  contains  an md5sink element, gst-md5sum-0.8 queries it for the md5sum at the end of pipeline iteration. If the pipeline
       does not contain an md5sink element, gst-md5sum-0.8 automatically connects an md5sink to the right-hand side of the given pipeline.

       See gst-launch(1) or the GStreamer documentation for more information on how to create a partial-pipeline-description.

       gst-md5sum is a wrapper script that runs the latest installed version of gst-md5sum-X.X. For  example,  if  both  gst-md5sum-0.7  and  gst-
       md5sum-0.8 are installed on your system, gst-md5sum runs gst-md5sum-0.8.

OPTIONS

       The following options are supported by gst-md5sum-0.8 and gst-md5sum:

       --verbose       Output verbose information. You can also use -v to specify this option.

       gst-std-options Standard options available for use with most GStreamer applications.  See gst-std-options(5) for more information.

       The following options are supported by gst-md5sum only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

OPERANDS

       The following operands are supported:

       partial-pipelinePartialppipeline description.
