Indeed, in the script found by checkbashisms, there is: echo To exit use Control C or press return to continue. echo echo -- read which will fail if using dash as /bin/sh.

The ‘read -r ’ bashism.
Dear all, in the ‘checkbashisms’ bugs of a package I work on, there is the following: checkbashisms' output: possible bashism in ./usr/share/EMBOSS/jemboss/utils/install-jemboss-server.sh line 607 (should be read [-r] variable): read I would like to forward this Upstream, but I have no clue of what the problem is, and how important it is. I have read ‘https://wiki.ubuntu.com/DashAsBinSh’, but found nothing there. Can somebody send me a pointer to some documentation?

I have read ‘https://wiki.ubuntu.com/DashAsBinSh’, but found nothing there. Can somebody send me a pointer to some documentation? My guess (although I am not by any means authoritative on this) is that this is just saying that writing read without supplying an argument is a bashism. In bash, read by itself reads a line into a variable named REPLY, but the standard requires a variable name to be supplied. Perhaps the fix is as simple as changing read to read REPLY. You can read about bash's read command by typing help read at a bash prompt. You can read the POSIX standard for the read command at http://www.opengroup.org/onlinepubs/009695399/utilities/read.html -- Ben Pfaff http://benpfaff.org -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe.
