How to setenv based on sed results (for gnome-keyring-daemon)

My problem

My main problem: I need to run gnome-keyring-daemon from c shell. In bash, it's pretty straightforward:

> export `gnome-keyring-daemon`


which is equivalent to:

> export GNOME_KEYRING_SOCKET=/tmp/0123.1.sds/keyring-abcdef/socket GNOME_KEYRING_PID=012345


My goal is to get the same functionality in a c shell, but my command line skills are not up to the task.

What i tried

If I run

echo gnome-keyring-daemon

| tr '=' '' | sed s / GNOME_KEYRING_SOCKET / setenv \ GNOME_KEYRING_SOCKET / | sed s / GNOME_KEYRING_PID / \; setenv \ GNOME_KEYRING_PID /

I start well:

setenv GNOME_KEYRING_SOCKET /tmp/0123.1.sds/keyring-abcdef/socket ;setenv GNOME_KEYRING_PID 012345


Even though I can copy and paste this output into the command line and get it to work, if I wrap this statement in ticks to make it work on one line, I get the following error:

Invalid command null.

I researched it and saw that it has to do with a newline in that needs to be escaped or deleted; however, I still get the error even after adding replace commands for \ r and \ n like so:

> | tr '\r' ' ' | tr '\n' ' ' |


What i am looking for

I really need something that I can add to my .cshrc file that will run the gnome-keyring-daemon. If I'm wrong, I'd love to hear an alternative approach.


One last thing I tried

To really simplify this, I also tried to just set one variable at a time:

setenv GNOME_KEYRING_PID `echo -n `gnome-keyring-daemon` | sed 's/.*GNOME_KEYRING_PID=\([0-9]\+\)/\1/'`


Which also gives me the "Invalid null command". even though this works:

setenv GNOME_KEYRING_PID `echo '1234'`

Thanks @shelter and @gbulmer for your help. I really hate answering my own question, but it might help someone in the future ...

In the end, I updated my C Shell script to set the variables on multiple separate lines:

set gkd = `gnome-keyring-daemon`

set pid = `echo $gkd |  sed 's/.*GNOME_KEYRING_PID=\([0-9]\+\)/\1/'`
set socket = `echo $gkd | sed 's/GNOME_KEYRING_SOCKET=\([^ ]\+\).\+/\1/'`




Have you tried echo -n gnome-keyring-daemon | ...

echo adds a new line
