Still trying to get the basics down and I would like a different solution to what I'm currently doing and a better understanding of why it's happening. I've written a simple backup script that tars...

Noted.

However, I can run the command without the -E option and it will parse correctly.

In the man file I quoted, the structure seems to support both -E and -s in the same line.


Thanks...

Just playing around with process substitution.
Hoping maybe someone can give me some help on what I'm doing wrong.
When this script is run, "Null message body; hope that's ok" is returned and the...

Maybe SSH to another box and issue the mail command there..?

That way, stdout and stdin never hang but never go anywhere either

Cool! Still learning this stuff :o
But I meant why would you redirect /dev/null into stdin? The reverse makes sense..

I'm not really following this.

I'm not either..
Can you tell me why you would pipe /dev/null into stdin?

Also,
exec 0<&-


What is this?

I don't want to redirect stderr, and have already redirected stdin and stdout to /dev/null. I expected ls to inherit stdin and stdout from the shell

Yes but you haven't redirected stderr, which...

ls -l /proc/self/fd >&2
You are redirecting stdout (what ls is producing) into stderr (&2).

Unless you tell the script to dump stderr to /dev/null...:
./myscript 2>/dev/null

...it will be...

Hopefully I'm understanding you correctly. Your first sentence made my mind go in a loop.

find . -maxdepth 1 -type f -name test -o -name temp

find . -maxdepth 1 -type f -mmin +45 -print

I've got something to this effect:


read -n1 -p "Continue? (y/n)"
if [[ $REPLY == [yY] ]]
then printf "\n" &&
cp -prv $WODI/* $OTHERDRIVE &&
chown -R...
