I would like to parse the output of cdrecord/wodim using grep.
cdrecord -v outputs lines like
Track 01: 49 of 75 MB written (fifo 100%) [buf 100%] 10.2x.
The problem is that cdrecord uses carriage returns (
\r) in order to show the progress in the same line.
I tried to append
tr '\r' '\n' to the cdrecord call, which works generally, but the output won't show line by line. Instead, large chunks of text are parsed and displayed:
cdrecord -v ... | tr '\r' '\n' | grep -i written
Is this due to cdrecord, tr or grep? Is there any way to force flushing in order to get the output line by line?
Any help appreciated.
