LFS Chapter 5.7 bad substitution

MP123 · 02-05-2007, 10:40 AM

Hello again.

I get a bad substitution message after I type this message

Code:

mv -v /tools/$(gcc -dumpmachine)/bin/{ld,ld-old}

What could have gone wrong there?
and how can i correct it?

thanks

What shell are you using? Does /bin/sh point to /bin/bash? Your syntax looks OK - I copy pasted it into a terminal here and it worked...

Bash 3.00.16

The /bin/sh link target is /bin/bash

The only other things I can suggest are:
- Check what the output of gcc -dumpmachine is;
- If the output of gcc -dumpmachine is correct, check that the ld files exist. On my system I'd use this:

Code:

ls -l /tools/i486-slackware-linux/bin/ld /tools/i486-slackware-linux/bin/ld-old

- If the files exist, run the full command manually. On my system this is:

Code:

mv -v /tools/i486-slackware-linux/bin/ld /tools/i486-slackware-linux/bin/ld-old

If it still doesn't work can you copy/paste the output of all of the above please?

I decided to do everything from the start and that code where i was getting the bad substitution message ran fine.

Thanks for taking the time to help me. I really appreciate it.

Now i have a new concern.
