I get Syntax error: Unterminated quoted string I wanted to @${REINPLACE_CMD} -e \ "s,\"machine/soundcard.h\",<sys/soundcard.h>," file It seems to go wrong there, what's the proper way to escape quotes in a s/x/y/ like this? It's included in double quotes (and wrong), I want to change it to a <blah> include. Thanks, Dan
