Package: dash Version: 0.5.7-3 Severity: normal Dear Maintainer,
to have a timestamp in front of every command that is executed, I tried to set the variable PS4 to '$(date)'. #!/bin/sh set -x export PS4='$(date)' /bin/true This works with bash and results in the following output: % bash ./test.sh + export 'PS4=$(date)' + PS4='$(date)' Wed Nov 7 21:55:10 CET 2012/bin/true If I run the same script in dash it results in a fork bomb. I suppose it's because when PS4 is evaluated and a sub shell is spawned, it inherits PS4 and reevaluates it and so on and so forth.
