Haven't done a lot with gzip nor bzip when it comes to unusual practices like pipes and the like.

* Re: piping output of dd through bzip2 ` Jason ` Gregory Nowak @ ` Steve Holmes 1 sibling, 0 replies; 17+ messages in thread From: Steve Holmes @ UTC (permalink / raw) To: speakup I just did and got it to work here. dd if=/dev/hda1 bs=1024 count=1024 |bzip >windows.img I noticed that dd of a 3.5 gig partition was gonna take a very long time. The output of my little test confirmed equal in and out counts but there was no output messages from bzip2; I suppose that's normal behavior for that program. The bzip2 man page mentions a -c option for standard input and output but not sure when that is actually needed. Perhaps so if a filename is specified but you want the output to go to stdout. I did my tests without the option.

* Re: piping output of dd through bzip2 ` Gregory Nowak ` Jason @ ` Charles Hallenbeck 1 sibling, 0 replies; 17+ messages in thread From: Charles Hallenbeck @ UTC (permalink / raw) To: speakup The '>' is probably crucial. According to the man page for bzip2, if no filenames are specified, standard input and standard output are used. As I read it, that means if you specify an output file without the redirection symbol, bzip2 no longer accepts standard input. So if you want to pipe the output of dd directly into bzip2 you must not give bzip2 any filenames. Redirection of the bzip2 output is the only way to do that. The dd man page implies that omitting the of= parameter implies standard output.
