This patch fixes it by resetting the handler when entering a subshell. Reported-by: Mart...

...shell - meaning something like the mysql command line, where once started it takes it's own commands, etc and keeps running until a "quit" command is issued. Now what I was wondering - is there a way to fork it to the background (something like # command & or ctrl -z) and have the subshell keep running? And also to be able to get back to the sub shell? For example, if i do run it with the & at the end it does what I want, yet obviously (to my knowledge) you can't get back to the subshell without killing it and restarting it. I have looked into the "screen" shell ut...

As noted on my blog and at http://www.opensolaris.org/os/community/dtrace/shells/ I''ve made available a DTrace provider for the Bourne shell. Before anyone starts yelling at me for not starting with another shell, read the blog I made explaining why we started with shell (link on the community page referenced above). For /bin/sh, I''ve put up something akin to a chapter in

...ited fd in the environment of both nbdkit and the shell script, but this is not an nbdkit leak. Furthermore, checking how many fds are open in a shell is tricky: many actions in the shell (such as a glob or pipeline) increase the number of temporarily-open file descriptors; I settled on creating a subshell, then using ls to check the files still open in $$ (the subshell prevents the parent from using any more fds, all without changing $$). This addition is rather fragile - if it causes testsuite failures in some environments, we may end up reverting it. Signed-off-by: Eric Blake <eblake@redhat.c...

I outline the first two methods in a blog post you may find helpful:...

This may sound stupid.. so bear with me for a moment. Assuming the only access I have to a machine is through asterisk -rx can I use the ! command? asterisk -rx help includes the ! command, but I can't seem to get it to work ie: asterisk -rx "! ls" Any help?

unfortunately, we keep getting this warns into the system log by puppet masters: " [...] Unrecognised escape sequence ''\<CHAR>'' in file <PATH> [...] " but then everything works fine; also, without using escapes, catalogs dont work on agents. What can we do to avoid these kind of errors in master syslogs? Please ,let us know ASAP and tell us if this
