Let’s say I have a script like the following:
useless.sh
echo "This Is Error" 1>&2
echo "This Is Output"
And I have another shell script:
alsoUseless.sh
./useless.sh | sed 's/Output/Useless/'
I want to capture “This Is Error”, or any other stderr from useless.sh, into a variable.
Let’s call it ERROR.
Notice that I am using stdout for something. I want to continue using stdout, so redirecting stderr into stdout is not helpful, in this case.
So, basically, I want to do
./useless.sh 2> $ERROR | ...
but that obviously doesn’t work.
I also know that I could do
./useless.sh 2> /tmp/Error
ERROR=`cat /tmp/Error`
but that’s ugly and unnecessary.
Unfortunately, if no answers turn up here that’s what I’m going to have to do.
I’m hoping there’s another way.
Anyone have any better ideas?
