Subject: RE: 1.7.5: Bug with bash read in /etc/profile.d invocation

OK, I changed my script to have:
	read -p "How are you today? " Ans </dev/stdin But I now get "bash: /dev/st=
din: No such file or directory"

Since profile is redirecting stdin & stdout, wouldn't it make more sense fo=
r profile to redirect stdin and stdout back to normal when sourcing the pro=
file.d scripts?

Thanks,

Dave=20

Thanks for the info.  This didn't happen in 1.5.25 so something with 1.7.5 =
is different.  I'll go back to my 1.5.25 setup and look at /etc/profile and=
 see what's different.

Look at /etc/profile where it runs the profile.d scripts.

The scripts are run with standard input redirected to a here document gener=
ated by a find command. That is the source of the "/etc/profile.d/xinit.sh"=
 you're seeing as the answer. The "read"
statement in your script is actually consuming one of the arguments intende=
d to be processed by the "read" in /etc/profile.

Because the scripts are sourced by the current shell your "#!" line has no =
affect ("-x" isn't getting set.)

In other words, the shell is doing exactly what it has been told to do. Don=
't use a read in your profile.d scripts unless you make sure to reroute sta=
ndard input back to the terminal.
